So it is running now huh? pics man...geez. I don't believe you https://www.nopistons.com/forums/pub...IR#>/smile.png

nick....... i have to see it before you go..........



elliot..... very nice work..... now it is my 7's turn lol!

on the stock ecu?

Ya thats what Ide like to know.

Ignore the #10 run( the low torque run); I tried to have the dyno operator do a comparison versus the old SSA manifold and his old O turbine wheel and .81 turbine A/R versus my manifold and the new P trim turbine wheel and 1.32 turbine A/R, but for some reason a dyno showed up that I have no idea what its from.



Here are his relevant mods:

Rtek 1.7 ECU: new 550 primaries, new 720cc secondiares walbro 255lph hp and new 5/16 hardline from tank

HKS AIC 2 x 380cc

3.5" downpipe/midpipe to a modified Apex N1 catback

Cold air intake

No ac/ps/clutch fan

Water / Alcohol injection( intake temps start @ 22c and rise to 33C for this run)

Garrett B25 compressor section( 52 to4E basically I believe), P trim turbine wheel, 1.32 divided tang housing

Intake ports open slighly sooner than stock, exhaust is port matched to sleeve

Compression is low ( 60psi even both rotors, all faces)

* worn out drivetrain components are also have been taking a severe beating, making a lot of noise, probably hurting drivetrain losses.



This is an electric chassis dyno. I was told by the owner they have noticed results 10-15% lower than their neighbor shop with a Mustang Dyno, now whether thats true or not I have not confirmed.



Also after 6k rpms when the torque is dropping off pretty hard, we believe the car is being limited badly by the rtek 1.7 ecu's ignition advance, and probably the afm too.

Here are a couple of his previous dynos:

The lower torque dyno was:

SSA manifold, downpipe( 3" or 3 1/8") and midpipe to apex n1

B25 with O trim turbine wheel and .81 turbine a/r tang

Rtek 1.7( 550, 720), and a walbro 255 lph hp

afr's were in the 12s



The second run with the midrang torque jump was after

I made a water alcohol injection setup at the shop and street tuned his HKS AIC( 2 x 380cc )

Also fixed his cracked SSA manifold

Not bad for stock ecu https://www.nopistons.com/forums/pub...IR#>/smile.png
