+1...impressive. Any feedback on the feel, performance of the 5AT with those numbers and any issues at WOT?

sick numbers bout time some one pushed the PE kit......

fun fun fun

 

whoa..19lbs? that's the highest number (psi) i've seen so far
but then again,i could be wrong

 

I give him +2 !!!

 

Nice..... good job representing hte PE camp. I'll be joinging you soon lets hope.

A question: did you remake the poorly fabbed pre-FMIC y-piece that joins the two charge pipes together? Or did you guys no longer use that part with the new custom IC?

Again, awesome numbers, especially on the AT. Did you tighten the clearances on the torque converter? That can get you another few hp's and more importantly cool down the tranny fuid.

 

Dyno sheet will be posted tomorrow. I wanted to drive it so bad had forgot to grab a print out. My bad

 

no turbo lag thats for sure and it shifts real smooth in auto or maual mode. It sounds like star wars @ WOT

 

there you go, if it sounds like start wars (like whistling jet sound), that explains why the power output is low (and it is for that hihg a boost). Find out what they did with the y-piece.

the whistling sound, if that's the case, is an obvious indicator of a restrictive exhaust... that's what my car sounded like with the original stillen exhaust. After a swap, that was gone, and replaced by a normal engine 'grunt', albeit at far higher amplitudes.

We'll know more when you post the dyno sheet, looking forward to it.

 

538 does sound low for 19 psi. Not saying that 500+ RWHP is low. But there are guys with over 500 RWHP on the APS and Greedy TT with less than 13 psi. Are the turbos small on the PE kit?

 

No, the turbos are PERFECT for this motor, up to about 16-18 psi they are more efficient than anything out there, even garretts. It's eveyrhing else, like i described above.

 

Excellent.

 

Perhaps the number is (*relatively*) low due to the fact that there is more loss of power through an auto trans. I made 530 rwhp at 12.5 psi with a similar setup (no head work however) on 93 octane at 6800 rpm. Also take in to account that they auto has different gearing than the numbers everyone is used to..... Great accomplishment, nice work.

compression makes a huge diff.. look at the srt4 200 or so or vr4.. 11s lbs stock and putting down only 250-300 and its 3.0 so not too far off..

if those cars would run 6 psi.. it would be like a non-boosted honda..

on our cars 6 psi =350-400.. due to compression what is it.. 10.3 ?? vs most turbo cars 8.5 or een 8.0

 

just wondering did you ever dyno your car on the stock psi?

 

PSI means nothing. Its air flow that matters. You can have a small turbo @ 20PSI and a larger one at 12PSI and the large one will make more power because it flows more air. But you are right about the compression.

 

This is my car on 12.5psi with 8:8:1 compression. Disgregard the 10psi on the dyno chart.

 

exactly...on my supra i ran 21pnds on the stock twins probably making around 410rwhp....on my single at 18pnds ill probably make close to 525rwhp so on 3pnds less boost on a larger turbo im picking up over 100rwhp

 

That's because the smaller twins were too small in teh firstl place, having lower efficiency on the top end of the rev range (where the flow is highest). If they were correctly sized twins vs correctly sized single (assuming the same calculations were used), then you will get identical power, aslo assuming compressor efficiencies are equal.

 

the more practical reason for the low numbers at 19psi is the fact that these turbos are smaller compared to those of say the APS or Greddy kits.

this kit is designed more for response than bigg power gain....but dont take it litely this kit is very powerful and will def toos you in your set.........I should know i rode in a race preped z equiped with a PE TT kit

its a pretty ideal kit for some one who wants to road race

 

Yes but you also have to take lag differences into consideration! it also won't make that identical power in the same way. A twin turbo car usually is alot more of a gradual dyno, where as a large single is a very violent, more vertical pull.
