I'm sure we will find the power, it's just a matter of time. I still think the extra 25 degrees and the 90% humidity played a major roll in robbing hp. I bet it will be different when I dyno on a 70 degree day like the last time

 

Could someone point me in the direction of the Helix graphs?

 

Jan, Did you get it?

 

no, send it to jbrueg@***.net

 

Maybe you should have turned the air conditioning off?

I'm sure Jan will figure out what's going on and they'll get your car seeing the light in no time!

Thanks for keeping us posted as things progress!

 

just sent it again Jan

 

I just went back and looked at longbords 1st post and dyno for this head and my graph is much smoother then his

 

I finally found the Helix dyno chart...
Here it is.

You also might want to note that the Helix car had a 17% pulley versus a 15% on RIPPER. The Helix car also had a GIAC tune, while RIPPER doesn't make any mention if he had a tune or not.

So it seems based on his car setup that the gain is completely reasonable.

 

the GIAC tune was NOT optimized for the head, it was only for the pulley
you of all people should know how tuning affects the car
it was DELTA to DELTA.... or doesn't that matter to you?

 

As a point of interest... my car with the RMW head will be at LDG getting tuned next week..... (Jan, the original pulley and the Magnaflow go on today)

 

thanks Bob,

It will be good to see what LDG can do

 

Yea the tune helped out Danny's car good,

So the Delta on Rippers mini was about 13.5 at 6800 RPM...Hard to really see on that dyno sheet.

That's on a stock cam I assume and many variables to consider I agree.

Thanks everyone for posting your results this is a great thread!

Good Luck! I am eager to see the results as I'm sure you are as well

 

Yes, the tune on Danny's car made 4whp and lost torque all through the low end to mid range

With the raised rev limit it made the power back


OT: you never did return the email about why your car only pulled 196whp on the same dyno danny's made 251whp on. You showed your car dynoing 225whp on another dyno. Just curious

 

I'm all for raising the limiter, you know that If there's power there and it's safe why not?

I just read your post in the other thread, I wish somone would combine those two...considering it's the same topic and discussion.

Thanks for the e-mail, I just got to it. I got off a vacation trip up north and a Dr. appt this morning. I pulled many parts off and went back to stock software at stock rpm of 6800 vs. the previous 7200, when I pulled 224 It was on vp104, I told you that. umm...oh and it made 198 Plus it was dirty west coast air j/k Anyway you know how variable dyno's are, don't you?

 

I thought that answer would be obvious


I must admit I do enjoy the dyno racing banter he said she said but proving how much your car is making on the drag strip is so much easier

Maybe thats why the drag racing threads are so short because you cant argue with factual evidence instead of the dyno variables:impatient

 

This topic just came up (20 minutes ago) in a discussion with John from LDG... you tune differently for the track vs the strip.... max power is not the name of my game as it seems to be yours, nothing wrong with that just a different application..... power that is useable for 10 -20 laps without breaking is my game.... John has an EVO that he purposely tunes down to 500 whp for the track which he says he can easily tune up to 600 if the strip was his "game".... all this max power stuff skews the hell out of the question..."what do you want to do with the car?"

 

There's lots of dyno racers here, you need a helmet to be a dyno racer?

 

I don't get it
+1 ... When I tune snowmobiles for grass or ice drags the set-up is completely different than a sno-x race...You tune your machine, or mini, for what your going to be using it for.
NO!! No experience required, but a handy cam and a youtube account will get you far,

 

It's definitely right along the lines of rustyboy's dyno.

Forgive me for being a little confused with the discussion here about tuning, I thought Longboard's car made 231 with the stock cam and ECU.

 

Unfortunatley everyone has the wrong impression of our car being a "drag" car, this is why we 've put a lot of interior back in it but due to it being so quick we've had to add a cage in it to meet rules. we use it as much as we can and will drive it to the track this weekend.

Due to the way 1st gear is and If I drop the clutch at 7400 it drops to 3200 so I've been concertrating on trying to make more trq from 2500 and up as I wont be launching that high with the nitrous.

Good luck at Johns cant wait for the result and I'm sure I'm going to be jealous of your finished trq numbers

 

Actually Longboards results were the launching of the RMW head. His results have been (dare I say it) miraculous! I am hoping after a proper tune to report similar results.....

John (Jan as well) and others who have been down this road with the Mini agree that the tune is ..... well... damn close to everything (please excuse the very broad brush). It makes a huge difference and the problem for us Mini guys is that we really have had few good tuning solutions..... Bolting on parts means very little if you can't pull it all together (this adds to the stunning results from Longboard with NO tune).... that being said, if you can pull it all together with superior parts, ie the RMW head, you should achieve superior results

 

May I quote the legend David Vizard " the engine doesn't know what name is on the rocker covers" maybe you could apply it to heads as well.

I wouldn't of said that a stock cam could acheive the same as a high lift cam and have a better area under the curve but it does.

 

no arguement with the cam... that is a whole other area that needs research..... so far it is Scrick or close to nothing and many of us know that there is something better.... I know that there will be announcements coming with regards to cam grinds...... let's face it... the Mini engine is a relative babe compared to a lot of other engines and a lot more R&D needs to be done.

AS far as the "cover"... I totally agree.... I just want results not badges...... someone joked that performance in the 80s American cars was judged by the number of decals, banners and badges.

 

There was a vendor who said that a month or so ago and everyone badgered him so much he hardly posts anymore

 

I hear what you're saying about a tune, Bob.

I think maybe calling the RMW head superior maybe a bit premature.
No one has been able to duplicate(or even come close) to Longboard's numbers with just the head, basic mods and no tune.
