I've decided on some power mods to add to the new suspensoin that is going on my car, and was wondering how much HP you think I will get? I'm sticking to pretty much bolt-ons for now, but will be re using most of the parts when I build my "DEATH ROCKET" motor I have planed.

1) 17% SC pulley
2) 4% crank pulley (possibly)
3) RMW street header (heat wraped)
4) M7 DFIC 2
5) GTT 63mm throttlebody
6) Mynes 550cc injectors
7) Unichip w/ tuning software
8) Custom tune to run E85 (nothin like the smell of 110 octaine CORN)
9) Alta V2 intake (already on the car)
10) My custom 2.5" heat-wraped strait pipe exahust

There might be more parts but theese are the big 10 that that I have planed and remember I dont want to go to internals on this motor ie- cam/head, I'm geting a new block for that. Let me know what you think?

 

250-260 whp is my guess... do a custom tune instead of the unichip though.

 

 

Ditch 2, 4, 5, 7 and get a custom tune and you are lookin at about 215-225whp. Around 240-250 with a cylinder head. I would spend the money you would spend on 2, 4, 5, 7 and get a water/meth kit.

 

Silvermini IS RIGHT ON. Those mods ARE a waste Of $$ and would pay for the meth kit.Nothin WRONG w/em just--- time it different----dyno in between; then let us know-----COOL !!

 

First my reason for the one product that most people tend to HATE)I am not going to run UniChip's maps on the piggyback, I have a good friend that HAS/CAN tune the Unichip. The company sells the software and cables to build your own maps and I am going to buy the set and learn how to use it when my friend and myself do our initial map. The good thing about it is that you can store 5 different maps on the unichip itself and even more on your laptop. That means if I take the car cross country and the truckstops dont have E85 I can switch tunes to one to run regular gas in about 30 seconds. And if I want to build a map for expencive race gas, it is really simmilar to properly tuning an AVC-R fuel controller. I could go on and on here but that is enough on that subject.

Second The larger throttlebody) I dont really expect much more peak HP, I do know how they can change the powerband to a higher RPM wich is one of the reasons I'm going this route(Easyer to get the car to launch off the line) The other reason is just throttle responce, plain and simple they can be verry touchy. Think of it this way your engine is getting a set amount of air controlled by the throttlebody at all times, at part throttle the amount is limited by you(gas pedal) but with a larger bore and throttle plate this same amount of airflow is acheaved with less throttle angle, boosting responce. Than at wide open throttle(WOT) it is mostly dependant on manifold/head port size just the intake charge can get to the ports faster/ however R53's are supercharged they are craming the air in anyhow But they also suck the same amount of air through the first half of the induction system. The more air volume you can get to the S/C the more it will dump out the other side and compress.

Third the intercooler) I love the design, it is like a condenced front mount. But it does have 2 drawbacks 1) it is too deep of a core the incoming air (outside air)needs alot of velocity to stay cold goin through its 7" of thickness. 2) Its restricted air path, It is in my oppinion better than the stock 90 degree turn method, but there are still restrictions before and after the I/C core. M7 improved on the inlet side by including a front scoop that catches more air and re-directs it strait to he core. than on the exit side it just dumps into the engine bay with nowhere to go, Unless you spend the extar cash for the M7 exit scoop or cut a hole in your hood and make your own.

Meth kits) Why add a little bit of water and alchohol to an engine that is already running on the 85% alchohol in E85? Just running the E-gas reduces combustion temps way more than a $400.00 high tech squirter ever could, reducing knock and allowing for more performance orented timing curves. The only down side is you need ALOT more fuel a minimum of between 30%-50% and the smell

Sorry for the LONG a** post, just thought I would share some knoledge

 

Do what you want but a water/meth will put down more horsepower than a throttle body and intercooler

 

In theory it should be a benefit but you need to research more. I believe it's not a popular mod because there are other bottlenecks on the airflow. In other words, you need to upgrade more than just the throttle body to get benefit out of it.

A 3rd drawback... all of the aftermarket intercoolers including the M7 have significantly higher heat mass than the OEM. They work well until they heat up, then take much longer to cool down while actually producing higher temperatures than OEM. There has been a lot of testing and posts on intercooler performance. Even if there is any benefit to "upgrading" the intercooler, it should very far down the list in priority.

 

DrsilverMini you are not geting the point If the car is already running on 85% alchohol anyhow adding methonol(which is you gused it alchohol) and a little water will not do much for me. So it makes your water meth kit USELESS on my car or any other car running E85(alchohol) for fuel. Dont get me wrong it does work great on any gasolene(not alchohol) based fuel, but sorry it wont do much for us that burn that $2.00 a gallon 110 octaine CORN fuel.

And yes rkw I hav done alot of reserch into throttlebodies and have used larger ones on some of my other projects(the 70mm on my old Honda CRX) and found that at my altitude with a good tune they can be quite benefitial, at 6000 feet any little bit of air mass you can get is a good thing but at sea level I didnt notice much other than tuch the gass pedal to hard with the clutch pushed in and you are at 5000rpm before you can com off the clutch. As for the intercooler you forgot #4 pressure drop you can actually loose 1-2psi of boost by going with this size of I/C core and bigger does mean more heatsoak over the small stock unit like you pointed out. However at its peak performance the larger pice of any brand will cool more air, to help recover from the heatsoak use a water sprayer just a couple ounces at 40mph and your I/C is ice cold again. With every buildup you need to make compromizes in some areas and theese ones are hard to get around.

No hard feelings tward either of you, You both bring up good points but there is always a situation where what works for one wont work for the other and, what One likes Two hates. But that is part of the automotive culture, it is what sets us apart from the Prius lovers of America club

 

****'s Garage: You can do whatever you want, but you asked--and most of the answers are based on year's of experience with the R53. ...and yet you want to argue with them.
I run at 5000-7000ft (Albuquerque, Santa Fe) all the time, and a throttle body is NOT on my list of mods. I have almost every mod you mention in your list, and without a big valve head and cam you won't get anywhere near 250WHP. I've never seen it and never will, unless all the dyno gods were smiling in unison on that day and place.
I know you are new to NAM (42 posts since joining in Feb 2010)--and this is a long standing group of R53 folks who greet all newcomers with an extended hand. But if you read a few of the older threads on any one of these mods, you'd find out a whole lot and avoid having to write posts like #9 above.
Or not...

 

Point taken however I am really not looking to get anything over 230HP untill I do build a long block and it will have a head and cam. But I am keeping what I already have installed including the E85 wich burns colder than race gas. The last I heard about E85 on this site is to stay away from it and that it cant be done, but look at the japaneese crowd your either burning corn or you are concidered a minority. There are EVO's with over 1000HP coming out of 2.3 liters of displacement running on E-gas and an engine is an engine as long as you keep the temps down and give it enough fuel it will make power.

OH and you dont need to **** out my name I am proud of being named ****

 

My bad it does that automaticly, well s**t someone come up with a nickname.

 

If you do a 17% pulley, and a 4% overdrive...you will likely destroy the stock pistons...so until you do new, stronger internals, I would not go beyond a 19% reduction total....
Even with custom tune maps on a uni-chip, thet are farrrrr from ideal...the adaptive nature of the ecu makes it run sub-optimumly....RMW/Jan has a flash too that will let you switch tunes....would be a better option IMO, since you are actually reprogramming the computer, rather than tricking it with the uni-chip.
You might want to consider some improved charge cooling...a better IC....that is the REAL reason water meth kits work...the water/meth absorbs heat when it evoprates, dropping temps...the increase in octane from the meth is just a side benifit....it is all about where the water/meth gets injected....just through the fuel injectors do nothing to cool the intake charge...the higher octane of e-85 does make detonation less likely, but if you want to run more than 19% of reduction, and retain the ability to run pump gas...at 93 no less...you should IMO do the water/meth kit...you SC will be making some crazy high temps on any real rpm's...much above the. Common 15-17% reductions, you tend to make mostly heat, resulting in less power unless you stick to very low rpm's.....
Good luck....I'm interested to hear how it all turns out!! Sounds like a fun project!!

 

Yes ****, the site ***s your name! Weird.
I have seen some massive HP out of E85--so I say go for it. But (and it seems like you know this already) you will be stressing parts of the engine a lot. That said, there were R53s with twin charge and turbo-only mods that produced 300-600HP, and took some time to blow up...
So, again, I say--go for it!

 

I would save the bigger throtle body till after you do a new head with big valves....you a limited by the head.... You can try to flow a ton of air...but what you are doing is making back preassure for the SC to pump against....so you end up making more heat!!
The DFIM7 intercooler is nice...but it makes a bit of back preasure....and has longish recovery times....I'd go stright to the GP....but that is me!!

 

+1

 

Check out alcoholinjectionsystems.com---------#1 is basicly made for Minis and costs LESS than a wal mart on top of your intake !

 

The 4% crank pulley is pretty much out the window, I never really cared for them anyhow I just wanted to bring the boost up a couple more psi.

Intercoolers are easy to swap out for a different one if I end up not liking my M7, They are also quickly and easily sold.

I also trust my friends tuning abilities, Jan does incredible work at RMW but I've never heard of him messing around the E-gas. Tuning with this stuff is not as easy and requires alot of minor corrections after the initial tune, So I want it to be done localy by someone who had been burnin corn since corn could be burnt That way if fuel changes like it always does (E85 is really bad at this) and I need some help with it he is right there to help me out.

So all in all when I return from Iraq and start installing the parts and doing test runs I will let you guys know what I end up with. For now do you think 230HP is attainable or not?

1) 17% SC pulley / Get a 15% = less heat
2) 4% crank pulley (possibly) /
3) RMW street header (heat wraped) /
4) M7 DFIC 2 / stock has proven to outperform. Do some searching.
5) GTT 63mm throttlebody / Not needed
6) Mynes 550cc injectors / Don't believe you can tune these with UNI
7) Unichip w/ tuning software / Get a real tune.
8) Custom tune to run E85 (nothin like the smell of 110 octaine CORN) it's your car
9) Alta V2 intake (already on the car) /
10) My custom 2.5" heat-wraped strait pipe exahust / sounds cool

Here is my recommendation for solid power

1) 15%
2) Injectors
2) Head
3) Cam
4) Header
6) W/M system
7) Tune

Hammer it and have fun!

Longboard

 

Double post

 

Well, I don't know much about anything else you were posting about but Jan tuned and dyno'd my MCS to right about there with the mod's in my sig (I think I've done half of what you have planned) so I would say yes.

 

Richard (??) : Make SURE you see the medics and get some" docs" that you can hand carry----don't lose em. IF you're gettin out you're gonna find them "handy" !! You've been GIVEN a 100yrs of knowledge by guys who've BEEN THERE---you'll be cool-just gotta get that SAND outta your ears !! We're WITH you--no need to "defend" yourself here. JAN WILL set you straight & it'll BE GREAT !!------lol

 

and mynes (also in socal) can tune for E85 as well as those injectors, as they have already done so on one of their personal cars.

btw, you will also need a new clutch before this is over...

 

Thanks The clutch is already on the way, I smoked that sucker(and the EVO that was in the lane next to me) before I left home.

 

Oh I forgot since this site blocks out my name, those who **** me out at home just call me Rick
