We recently upgraded a local customers car from an ETS supevalue tubular manifold setup to the FiD EL v-band manifold. Both manifolds were running a GT3076R .63 A/R. turbo with the same intercooler piping wanted to post some test result between our v-band EL tubular manifold and v-band downpipe setup.

Vehicle Specs:
Evo 8 GSR
Stock longblock
Comp 272/272 cams
750cc injectors
Walbro 255HP
3" turboback
reflash ecu
3" Intake

Red Graph: FiD w/GT3076R TIAL v-band turbine housing .63 A/R
Blue Graph: ETS supevalue tubular t3 housing .63 A/R

With the tune unchanged except for lowering the boost, the car made more hp/tq and spooled quicker running ~3psi less boost with the FiD setup.




Here's the FiD GT30R setup at 23.5 psi on 93 octane

I"m really surprised people are still using the 30 r is still a great lil turbo..Nice test with the manifold's also I guess you pay for What you get. what was the correction factor??Also why such low boost??

 

There was no correction factor. This was just the initial boost level after upgrading to the new manifold setup. It was later tuned for 29psi.

MrC

 

How much did it put down with 29psi??

 

Here's the graph at 29psi



MrC

 

That's some nice power around 500 whp d.j.dyno numbers..Why does the power fall of so soon there has been a pattern on some graphs lately.This power band looks like just a peak number..

 

i guess this is on pump gas

 

nice looking manifold

 

Correct this on 93 octane.

MrC

 

with meth or e85 or q16 should be on the high 400s

 

Looks a tad laggy to me ,here is a gt30r on 93 and peak 29psi dropping to 26psi.

 

very good numbers on a dd dyno the tial gt30s are so nice

 

What were the run conditions between the two runs?

Maybe it is just the way the dyno loads the car, but I've seen single scroll GT35Rs spool better.

 

Really can't see the value of money to HP ratio on a setup like this? Why not just go with a red for better spool and similiar power. I know this thread isn't for that discussion but why did the owner go for this setup?

 

Just to throw it out there - but that's my car now. Well now it is anyways, as I bought it from AJ. I can attest that is is a _very_ well built kit, and my friend fabricates kits for mustangs and domestics for a living, so I have seen a few.

That 429hp run was _VERY_ conservatively tuned. 10 degrees of timing advance at full boost and mid 10's AFR.

Here is the sheet from AWD after I had it re-tuned.
Blue line was 25psi with the ptuning tune. Red was 28psi with Diiirk tune. At the same 25psi it made ~420hp just with the new tune.



I believe the original owner had it setup for HPDE and autocross.
