Ok...I'll bite...the two of you with the same sig...what's up

I too am curious about the whole twicharging scene since I too will TC my car or else get an Elise. I don't wanna hear about the he said she said stories since most of the time they have been blown out of proportion. So, my question is this, who is running a TC setup and has had some sort of reliability with it....also please make it clear which kit (SPI or Helix) and roughly the amount of HP being produced. Also, I'd like to hear what has been modified to accomodate the setup (pitsons, cluth, fuel management, etc). I know Maximusmini has had a very difficult time with his setup since he did have to rebuild his engine, but that aside, how has it been running after the rebuild? Reliable? I think anyone who is willing to put this on their car already knows that its aftermarket and well, there will be some problems here and there but i think the concern is to what degree?

One last thing, Tuls had said that he was blowing doors off moded STIs and Evo 9s...Tuls is this true? I know that ppl running the TC setup were struggling to run 13s and well lets face it, a STI could run 13s stock. So my only guess is that Tuls is talking about highway speeds or at least starting from a rolling speed of 20 or over. Please clear this up for me as I am really interested but if all this work is required and you cant even take something like an srt, cobalt ss or STI then its not rally worth the investment and I'd probably go towards the more aggresive Elise.

 

Wow...TMMZ splitting up? What happened?

 

Let me clarify...first off the EVO 9 was stock...and the STI was modded...either way it's not matter....

Yes we were moving already....

and yes it's possible to launch on these cars...remember...it's driver VS driver...not car VS car

 

This one will explain things a bit better than the one andy posted

We are just moving on to bigger better things. It will be good

 

There must be something I'm missing...all I know is that some of the former TMMZ members are leaving to create another group. But WHY? What happened?

 

[size=2]Can we please get back on topic here, TMMZ has nothing to do with twincharging. Thank you

OK, guess it's time to stop lurking.... :smile:
I do have an SPI twincharged MINI that is a track/road race only car, racing with BMWCCA. The kit was installed by Hubie and he has been giving us phone tech support since then. It has been to the track about 5 weekends since installation. We have been chasing issues each time, but seem to have everything addressed at this point. The only internal engine mod is forged CP pistons. It has NOT blown up. It makes great power!

Other mods we found were necessary after the install were silicone IC boots (blew holes in the factory boots) and a total fuel system upgrade, due to the factory fuel system's inadequacy. We also need more grip and will be addressing that soon. It is still on the original factory clutch (9000 racing miles) and has a Quaife.

It has been a little frustrating getting it all right, but none of our issues have been things that would be a problem for a street car. BTW, everyone who races seems to have similar problems - the only solution is to keep your car stock, but that wouldn't be as much fun to drive!

My MINi seems to be running very fine now, although I WOULD reccomend some Engine Management other than the conservative settings of the SAFC. That project is coming up over winter. It is VERY hard to hook up in first or second through the use of street tires. Although drag radials, I still don't hook up in first gear. After the rebuild, I have complete confidence in my MINI, I've even noticed a nice gain in gas mileage! I know the engine could take the abuse due to the addition of forged pistons, rods, and the titanium valvetrain. Now, i need to figure out the tuning of the engine management and some experiment with some other things. I sure have more mods to come.. especially in the braking and suspension category.

 

Ada, is it true that you took off 17 seconds per lap after you installed the SPI twincharger kit?

 

Thanks to Maximusmini and Ada. Your responses are appreciated. Tuls I know its driver vs driver but the car obviously influences who will win....so if you did take on both cars, congrats to you and the car, it must b real fast. Maximus, I have one more question to you: have eaten anyone up yet, like an STI, SRT4 or M3s? I would think with 250 to the wheels it should be able to take a M3 but the times just aren't there for some reason.

Thanks,
Luca

 

Yes, I have taken on the above and yes I have outran them, in many different attempts. There are many more, but if you would like to know I would prefer you to PM me about those.

 

I don't know where you're going with that, though. My car can run all day, in Florida weather, without extra fuel management or pistons, since I put down about 200-215 to the wheels. Hell, the dealer still thinks it's somewhat stock! . BUT, I'd like to put more power down, hence trying to find a reliable and FUN way to do so. I realize that TC-like power will encounter some issues and need some reinforcement- I'm trying to figure out what.

Anyways, thanks for the insight! How much would you say that the parts cost amounted to, to get the twin charge and prep the car? Got any estimates on labor costs? Good luck with your running and hope it gets tuned optimally to fully enjoy the setup!

Now, who else is lurking out there just begging to post?? This is good, let's keep it going!!!

 

You have never shown a dyno yet that shows you have made 200 hp. Forgive me if I'm wrong, but you have a tendency to exaggerate.
For instance, when you said you installed your Cosworth kit, then after someone pointed out that you didn't you changed it.
Then you said you talked to Jeff Perrin, then you didn't. What are we supposed to believe?

 

LOL. Ok, first, no, no dyno, just going on results from other Cosworth cars [2 dynos have been run one at 202, the other 218]. I will gladly provide links. That fact does not change my ability to infer, nor the point of my statement. It is not enough power for my plans for the car, specifically speaking.

Second, I am/was in TMMZ. I said, "they told us" when referring to Alta. We DID talk to them, and believe it or not we do talk to each other. An article is in press, so to speak. Nothing lost in translation. Similarly, nothing was gained by your above post. The kit is planning on low 4k, and intending to be the cheapest alternative.

Let's return to what is finally a meaningful discussion of twin charge possibilities!

PS: This Friday I am getting custom software for my car. It is then that I will PAY to get my own numbers. It is then that I will post my results for the rest of the community. Maybe even you can see them, mr. "mute".

 

insoc, this thread is not about your car, it is about the t/c kit. No one cares that you can drive your car in Florida heat when the t/c has been tested in Phoenix which is much hotter. Please stay on topic, this is a great thread, maybe you should start another thread to talk about your car. I want to talk about the t/c ing.

 

Please, stay on topic. I don't want to see this thread turn into all the others.

minimute, please watch your comments. You do not speak for everyone, so do not make such a statement to ingsoc.

Everyone, please stay on-topic about discussing the twin charge.

OOh! Maximus, I'm envious: it's purty . Maybe not to the people racing you !

So, please, can we get some more input from twincharge owners who track their cars? So far, this has been a historic thread - let's keep it going!

Ada- if you'd be willing, it would be phenomenal if we could get an estimate on how much money it would take in parts and maybe even a one-time installation to acheive your lovely results ! We all know it won't be cheap- power costs $$$$ - but we don't know much more. Thanks!

 

To answer your price questions. I paid around 5600 for the kit. Then after the Piston blew, I had to pay for 4 pistons, rods, bore the cylinder walls out, Titanium valvetrain, and Clutch and flywheel. The repairs add up to around $7,000.

 

oh god, feel like I'm 8 years old again just reading this.
Think I'm gonna be sick!

 

When members posting act like 8 year olds, they are treated as such. Don't be sick, be aware.

Wow! Did the clutch, valvetrain, and flywheel need replacing due to the piston? Or did you do this as a preventative measure?

 

Well you go then Core Moderation Team!
