Thanks in part to all the information on this forum, I finally got my turbo setup together and tuned on Tuesday night. Wanted to share the results for reference to other members.

This is on a low mileage AP1. Bolt-ons as follows:

T3/T04E turbo
Exhaust/Intercooler set up by TC Performance
ID1000 injectors
Walbro 255lph pump
Full tank of E85
Tial BOV and Wastegate
AEM v1 standalone
AEM EBCS
Competition Stage 4 clutch (6 puck disc)
Stock F20C motor, stock tranny, stock rear diff

Put down 397whp and 307ft/lbs of torque at 20psi running a full tank of E85 on a Dyno Dynamics dyno. Car was tuned at Revolutions Performance by Servion Tuning. Revolutions is located in Colorado Springs, CO which is at 5,800 ft elevation. Car drives amazing!

 

Either turbo ran out of steam or manifold was to restrictive or u ran out of fuel. But def decent power. Congrats.

 

Which manifold?

 

Turbo definitely ran out of steam! We hit something like 395 whp then cooled the shit out of the IC and intake mani, did a pull expecting to see something like 410 and all we gained was 2 whp Must be a small T3/T4.

It's a bottom mount log manifold. I'm pretty sure it was built by TC Peformance but looks similar to an Inline Pro unit.

 

the log manifold is holding you back 60-100whp

 

The log manifold is definitely holding you back but not by much. You would not see much more horse power out of that turbo even if you switched manifolds. The turbo has reached its efficiency. If you switched manifolds you may see 20-30hp tops.

 

but remember guys that was on a Dyno Dynamics, not a Dyno Jet. so on a Dyno jet he would have put down 456whp...gratz on the #s

 

Dyno Dynamics is a heartbreaker dyno. Good numbers man! Especially at that Altitude. I've seen a turbo S2k put down 500whp in Kansas City, and moved to Colorado, went to a track day and ran a 13.1 @ 113 mph with something like a 2 sec 60' time. Impressive stuff man!

 

log manifold rob a lot of power. Look at my signature and you will see how I went from 335whp to 400whp on 91 octane with nothing changed except going from a rev hard log to a tubular mase manifold.


also what kind of turbo do you have? a t3/t04e means nothing and hundreds of turbos fall into this category.

 

Not necessarily. Those dynos can be x factored and u would never know. Him being that elevation I bet there's like a 20% x factor In it.
