Well I just got my car back and went from Stage 4 to a Stage 4GT and for my Bar is hitting 1.5?? Is this to high??

Also I have the Sachs Stage 2 Clutch installed and when I release the Clutch I have a Very loud knock from under the car which sounds like a bad throw out barring...

Can one of you tuners please give me some feedback on both issues..I tried calling the shop that did the install but they are closed and this will drive me nuts all night...Plus Todd at EVO is gone for the evening...

Thanks..

 

When I had a high performance clutch in my supra, I used to get that knock - they call it Clutch Chatter. However, it is supposed to be normal.
On the Porsches......Stephen? Todd?

 

it's absolutely normal...
i just have my single mass flywheel installed too...
that noise come on when the clutch is not pressed in...
and u'll heard a bit of sound once engaged in gears... at low rpm when rolling...

 

John, the noise that you are hearing is 100% normal. When we replace the dual mass flywheel with the billet flywheel, the transmission "noise" is transmitted through the solid flywheel. With the OEM dual mass flywheel, the rubber center "soaks" up most all of the transmission noise, thus a quieter system.

Regarding the boost, the Stage 4Gt is designed to generate 1.5 bar in the midrange and taper off to 1.2-1.3 bar by redline. Call me if you need some more info.

 

Well then something is wrong with my stage 4GT. I see no where near 1.5 , nor 1.2 Tops I have seen in blistering cold weather is 1.1

 

i see 1.4 bar ^_^...and i'm using 100 octane
strangely enough...my car always have lower boost even as a stock turbo ^___^...

and Todd, is the redline raised? or are we still using the same redline as the stock?

 

My car is seeing 1.5 bar at 94 octane..I don't know if the weather has anything to do with it....But today it was 34 degrees...I doubt it...Todd thanks for clearing up the noise issue...After all is said and done...The freakin car hauls major ***!!!Specially in 2nd gear at 3500rpms at the punch...Major lag improvement over stage 4...Thanks a million Todd

 

Still waiting to hear from Imagine or Evo or both, please email me or call me asap.

 

Kevin, we raised the limit 250 RPMS.

 

Ryan, not sure why you are not running all the boost I will get in touch with Kaspar and find out what boost it was making when he had your car. I will call you in the AM

 

Hopefully, that's a sign of excellent programming, etc by IA. If im not mistaken, the promotive car (Tyson) was running 1.2 bar and producing about 700+hp? Maybe you're right on the money running 1.1 bar (with 650hp)?

 

Where is the extra 100HP when an Upsolute is running neck and neck, even thru 4th. Too much traffic for 5th.

 

Who knows? I ran with a stage IV from 3rd to 5th. Neck and neck until 5th when he started to walk away...but by that time we were well into the 100+mph range.

 

What does your car have, an upsolute?

Lou

 

I would imagine your car is really going to move from top of 4th on...

Next time, start in 3rd at about 60mph and see if you have enough road, etc. to run it up through 5th. Spool up time with the K16s and the upsolute is instantaneous....which is probably why he was able to hang with you. Im sure once you hit 5th you would start to walk away, etc. as the larger turbos would easily overtake the stockers.
