Title says it all.

There is post in Racing forum about a 951 getting to 300 hp just by using a Turbo Cup chip and being legal for PCA Stock class. Not PCA prepared does allow DME chips, but requires stock boost and of course stock turbos, AFMs, cams.

I dontt see how 300hp is possible in given those limitations.

I don't see it. Maybee, with very meticulous tuning, I could see 300 at the crank.

I had a friend tune a DTA stand alone running wasted spark on stock injecters/stock engine and a K26/6 who pulled a real 290 RWHP out of it. With all the factory support Porsche could put behind new fuel/igition curves (chip) and a /8 hotside, I'd say it is a definate possibility.


edit:

I should have read the whole thing the first time. With just a chip and exhaust, not on a real dyno that was accurate. Perhaps he used a GTech Pro . . .

300 at the flywheel.. I dont see that beaing too hard..

300 to the wheels however would be basicly impossible..

Ok, but was what with the stock DME, Chip only? Also stock k26/6 only please

I am having discussion with racer in this thread below (look for post #35). He says it is easy to add a chip to stock motor K26/6 car get 300 hp and still be prepare class legal. Not this means running stock boost, stock afm, stock head, stock cam, You can however run headers and open test pipe.

So you gain 70 hp and using the stock AFM, stock boost, Stock head, stock injectors, stock cam and ofcourse a stock k26/6.

Who is doing that?

Seems to me that everyone making anything close is running more boost.

Missin2

hmm.. rae gas.. lean that **** out.. and run alot of timing.. intercooler, underdrive setup, other boltons.. you could swing it..

M758

Must run stock intercooler.
What other bolt-ons?

Most stock cars put what...180-190 to the rear wheels? With driveline loss of 15%, talking 300 at the flywheel, which would get you 260 rear wheels on stock 8-9 psi of boost...not happening.

Well are we talking stock boost for original chips, or stock boost for Cup chips? The only way youre getting more power is with more boost. Maybe 18PSI is "stock boost" for those Cup chips...

I was wondering about that as well..

M758

According to PCA rules you can run as a prepared mod a DME chip. Turbo cars must maintain stock boost. If the cup chip increases boost the it is a no go.

Turbo Cup cars are listed in the rules at 250 hp. Same as the Turbo S. That would make sense if both cars run the same boost and the k26/8.

However I am talking about a k26/6 using factory boost for the non-S cars. Not boost level from the turbo S or anything else.

maybe it was realllly really cold outside.. and they dident use SAE corrections..

Campeck

its already done. lol

skunkworkz. i havent seen him around. if yall remeber my thread on the NA board about the dyno session. he has the 180 rwhp NA with headwork and exhaust.

anyway. if i remember correctly he had 260-280 rwhp with just a chip.
but maybe he was running more boost. i cant remember to well.
all i know is it was a chip...and thats it..and he was making rediculous amounts of power (so everyone said) for a k26/6

M758

Campeck,
head work is not allowed in stock class.

The issue is not can 951 get to 300 hp. We all know how easy that is. But can it get to 300 hp and still conform to stock rules that allow you to mod the exhaust headers and back, and add chip, but keep stock boost. Yes you can run race gas.
