".63 a/r T4" doesn't really tell us much about the turbo, but needing 26 psi to make 500 WHP sounds like a lot of boost for a full T4 turbo.

Yea, does sound like alot of boost for only 500+. I would have thought, it'll easily be in the 600+ mark at that boost level on a T4... &lt;head scratch&gt; unless it has a small T3 hot side...

This was on our Mustang dyno. Not your usual crazy high Dynoj*t numbers

should be making a lot more power with a pt67 imo.

Agreed, even on a mustang dyno. tygsr made 593 WHP @ 25 psi on an 81.5mm bore motor, and servion made 598 WHP @ 25-27 psi on a T3/T67 on an 81.5mm motor. The only big bore PT67 dyno I could find was hybrid901's, who made 620 WHP @ 26 psi on an 84.5mm motor.

There is still room left in the tune. Very conservative. But Im not seeing 100whp gains. Not saying those other guys dyno # arent true either. Those are all great numbers for that amount of boost. Any idea of what those cars weight and 1/4 trap speeds are? Set ups?

boosted92

hybrid901 has "10.66 @ 142" listed in his sig, but you should ask him for the weight and boost level on that pass.

servion has <TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by servion &raquo;</TD></TR><TR><TD CLASS="quote">SFWD Streetcar at ~6000ft elevation driven 65 miles to the track and home:
10.7 @ 134 & 11.1 @ 137</TD></TR></TABLE> in his sig, and since he runs SFWD his car has to check in at a minimum of 2400 pouds.

tygsr never posted about going to the track and he ended up selling his car.

Tuned1

NICE! I would also like to no there 1/8th mile mph and time to compare to ours was a 7.7 @ 104, since we havent made a full pass yet. fyi, Hondas (hatches) that put down around 500-550 whp on our dyno will trap around 138-140 mph. I just wanted eveyones opinions on the graph, more so than the hp numbers...

Widebody1

Good graph guys, the torque dosent fall off like most you see on H-T and the powerband is great!
Dont let the more accurate numbers from the mustang dyno fool you. Very solid 1/8 times so far cant wait for some full passes. There are some badass hondas coming from your guys shop. Good vids on your site also.

I was thinking the same thing.

99_GS-T

I believe Tygsr went 110mph in the 1/8 with his clutch letting go shortly after the 1/8. It was the first and only time out to the track and I think it still coasted to a mid 11. I believe the car was full weight minus the A/C.

93H22ACX

Dyno looks good. that 104mph trap should get you a low 7 1/8th mile depending on the track condition and traction.

94whtgsr

nice numbers, get a good pass in and ull be in the 10s before you know it....

Tuned1

my 60 ft time was only 1.8 on 24.5 x 8 x 13 M&H slicks. Still trying to find the right launch

Tuned1

What are your 1/8 mile mph's in those cars in your sig?

damn stop hating on him nice job

i did that on 15-16lbs with pt67, but none-the-less 104mph in 1/8th it good for low 7 and high 10 depending on car 1/4. and welcome to the 500club

it's not really hating, it's just that compared to others with that turbo the numbers are sub-par. great numbers none the less but i would think it should be a little better.

that is a pretty good powerband though. talk about a flat torque curve...

markaria

For a mustang dyno (i could only manage 331 on one ) I think your #'s are great! For reference, one of the local shops has a dsm (stripped/roll cage/built motor, etc) that could only put right around 500 on a mustang awd dyno and the car ran a 10.1 @146...

TurboJesse

i agree on the mustang numbers... we had a car put down 226 on our mustang, then we took the car across town to a dynojet and it put down 312...nothing changed...

Mase

its all how u set up those dynos...

ive seen the opposite too.

where a car made like 412 on a mustang and only 360 something on a dynojet

Tuned1

The dyno is set up properly. And we always use the weather station corrections.

g2turbo

Comparitively the power is low. Why did you stop revving the car at 8800? What tranny is in the car?
