No, not really. Mine has made 511-525 on 3 different dyno's probably 10 times in the last 7 years. All dynojets. 1.1 bar will do it, typical tune and exhaust. Diverter valves may be needed due to the old ones being leaky (oh and an FPR usually will suffice in place of injectors at this level)

There are plenty enough 500+ rwhp turbo's on this board to validate the claim. I don't think anyone said 550. And the 535 was a rough estimate guess with methanol injection. I think Tony from EPL could chime in on that.

 

Dynojets are way overated i watched a 16G billets 996tt make 562whp with only 1.3 bars on a dynojet but after that he went to a mustang dyno and made only 541whp at the same boost.

 

the question is how much rpm can a stock k24 spool....its about 175000rpm and thats around 1,1bar max...maybe you can go to 1,2 bar but after that point it overspin an create heat.....with 1 bar wastegates i remember a stock k24 can do 1,4 bar but with short lifetime

hybrids are the better way...

 

Yeah was on race fuel.

Not sure it works that way. 550whp gave me 138mph. It would trap 140 max IMO. I now have 670+ so will be interesting what that traps for a reference.

 

It must be a very, very low reading dyno or you are 3000lbs or less and or both!


How much do you weight?


Very, very impressive.

 

Time Slip? ET?


Anyone can spin their tires to gain a higher trap speed no offense but then your ET goes to ****…….I just noticed its a gt2 with RWD…..

 

the 996 i owned (rwd) had k24's with UMW tune. 5 bar, 2.5 x pipe exhaust no cats. it held 1.2 bar. i dynoed 503 rwhp on 93.
60-130 was 7.7

 

my EVOMS 'stage 2' GT2 with the old GIAC tune(2007), does a 127mph 1/4 on a street-kind 2.1 60ft....planning a re-tune/injectors/wastegates in the spring...will see what happens...
what's the brand recommendation for injectors(and size?72lb?) and wastegates nowadays on stock k24's? don't care about 1mile/drag stuff, roadcourse only. TIA!

 

If you have stock k24 dont go past 1.2 bars you blow hot air and blow the turbos. You need to upgrade to 18gs.

 

I'm in the same boat as you, roadcourse only. Kevin at UMW sent me a set of his injectors. They are stock injectors but modified for more flow. Obviously they are perfect plug and play as they are OEM. They require the fuel rail inlet to be enlarged for more flow.

 

A gt2 is in a totally different class when it comes to 1/4 mile times. As far as picking injectors , you must get them from the tuner you are or will be using.
Upgraded wgs will yield better times and or dyno figures on a k24. In order to hold solid 1.2 bar you need upgraded springs. Stock simply will not especially up on top.

 

thanks for the responses guys! Markski, could you PM me a price on a package deal?
Regards,

 

When I tightened up my stock waste gates per GIAC,, I held 1.2.

 

on a cold day

my point is with AM wgs the car will make more TQ and some power,...
most guys dont tighten wgs...

 

stock 24's vs 570whp vett
