^what numbers should the PL kit be making then? Still havent seen anyone making more than 500DJ on pump, with another user already saying he couldnt do any better either. Almost all the builds on the forums seem to be stock block 8psi...

I thought Snyper or someone heat wrapped the intake tube across the radiator and the dropped AITs significantly. With that big core, you shouldnt be heat soaked.

 

This is one of the primary reason why I purchased this particular turbo kit, along with the shops recommendations and knowledge of how the gt35r has performed on other platforms. I never believed that I would achieve 650 whp on pumped gas but felt that the kit would produce ~500-550 whp. I had discussed this with the original shop that the kit was purchased and the guy from Injected before I pulled the trigger on the engine build.

 

Is there such thing as a faulty turbo? Perhaps the turbo itself is what needs to be checked internally, verify its balanced, blades are not bent. I am sure its probably already been done but perhaps pressure should be measured at the turbo and at intake manifold to see if there is a significant difference.

 

remember you should be pretty close to 500 on a dynojet, which those PL #'s are based.

Increasing AIT's is an issue, but a meth kit will solve that in a second and then you can prolly get to the 550DJ

 

Thing is, increased AIT also means the turbo is starting to run out of efficiency, perhaps from too much pressure drop between turbo and intake manifold.

Ofcourse you get more AIT with higher boost, but as was mentioned the AIT is higher than anything they have seen. Meth will just be a band-aid however, yeah it might or probably will add more power, just will not be the most efficient setup.

Thats why I mentioned if pressure was measured at the turbo to make sure there isnt a huge pressure drop vs. the intake manifold. Just throwing ideas, im no pro.

 

I am see 170 degree + AITs when the boost level are increased past ~13psi and my torque is in the low 400s. I was making this much power at 8 psi on the stock motor. I was not expecting 600-700 hps but to max out at ~460hp is a huge let down after dropping the coin on the engine build and support mods. I am not trying to bash powerlab or Injected but I am trying to find a solution to the problem by posting on the forum. I would like to hear from all powerlab owners who have pushed past the stock motor/ 8 lb psi mark. Finally, I would like the have someone from powerlab contact me to discuss this issue; I can not find a direct phone number and have attempted to call Intense but there is no answer/ voice mail. Thanks

 

460 whp on a dd sounds normal for 13 psi. 170+ intake temps does not sound normal.

 

Dude, I was under the same impression when I pulled the trigger and purchased the powerlab ST from intense that I could ez get 550whp to the wheel on pump gas. 1 thing I dont understand is why can't u boost past 13psi on pump gas? If intense is able to run 29psi on race gas why cant u run 20psi under pump and just pull more timing?

 

I had done 21 psi with pump.. just for shat and giggles. AIT never exceeded 130, i only run 17 on pump on street. Anything else is a 50/50 mix. The turbine housing is too small. Look at a 35r on most cars, the housings are similar. Look at the PL and find that the hot side is about 1.5 inch smaller diameter.

 

I made 530whp on a mustang dyno down here at HP logic in florida on 18psi on a non moddified turbonetics kit with meth and pump with supporting mods. Seems the PL kit addressed most of the TN downfalls, so it should make more power than 530 :-D

 

DD hp numbers times 13% (1.13) will yeild about the same number as a DJ dyno.

WIth that high of intake temps something is going wrong. I'm thinking a restriction somewhere.

With 14.5psi on my vortech i just barely broke into the 160's for intake temps and that's with the small vortech piping and intercooler......

this sounds like there is a mechanical problem somewhere. I don't know much about turbos to tell exactly what would cause that high of intake temps.

 

what numbers were u making on 17psi? I would run meth but the powerlab takes up a lot of useable space that I have no room to run the tank near the motor.

 

where is your AIT sensor?

Is this your car?

If so, be surprised if it was the kit as it was already making power before the new motor.

 

what could be causing random high intake temps? unless when it was re-assembled there was something clogging the intake or another aspect of the kit damaged.

 

Hal tuned one that did 450 but said needed to be tuned down for longevity issues. STOCK block... somethings wrong with ur set-up.. stock block on mine was at 420 on a mustang dyno with plenty more to go i just cant risk it on a stock block.

 

In to find out what is wrong..... something is wrong....

 

450 on a DD would be roughly 508 on a mustang dyno so that's not the same at all.

you have a gt35r kit on your stock block making 420? how do you know how much more you have left in it if you never pushed it?

once you start breaking 450 dd (500 dj/mustang) a single pump fuel system begins to be a problem. apparently not the case here although it was the case on mine.

 

Im not trying to push it anymore right now cuz its a stock block but I can tell you my tune is VERY conservative. I had the timing pulled back some to be even more on the safe side. The guys at Japtrix were very impressed at what it was putting down with my safe tune. That being said I feel like it can go plenty more if I wanted to push it more. But at this time it wouldnt be pushing the turbo to its max it would be pushing my stock block to the max and prolly make it go POP. I feel the kit is actually pretty good and with what OP's got as his set-up I don't think its the kit itself being maxxed out. He's claiming it wont make "500" hp? I doubt that. I feel like something is wrong there.

 

yeah... didn't you do like 500whp on the haltech with stock block and race gas and low 10sih psi?

 

oh boy. why we must keep throwing the race gas out there. i think the point st8dum1 is trying to make is where is the 93 octane 500+whp dd runs. or is it possible
