I bought this car with the following list of performance mods. So far I haven't done any myself- I've been doing repair and restoration. I haven't done any dyno testing so I don't know what power it is making. It is very difficult to hook up the tires in first when the turbo spools up and it rips through second in no time, but I have no idea what kind of numbers it's making. just curious really; what do you guys think?

Engine Mods:
- Split Second ARC-2 Air/Fuel Computer
- Split Second ARM-1 Air/Fuel Meter
- Guru Racing DME and KLR Chips
- Speed Force Racing Stage III Mass Air Flow kit
- K&N Air Filter
- Greddy Type-S Blow-off Valve
- Speed Force Racing 2.5” intercooler pipes
- Speed Force Racing Cat-back exhaust
- 3" Bullet Exhaust Tip
- Tial 38mm Wastegate
- Manual Boost Controller
- Lindsey Racing Vacuum Hose Kit
- Lindsey Racing Fuel Pressure Gauge on Fuel Rail
- Adjustable Fuel Pressure Regulator
- Widefire Head Gasket
- Rebuilt long block
- Rebuilt OEM Turbo

Right now I'm running at 13 PSI boost.


Here's a picture of when I first got it.

what Turbo you got in there??

EDIT you put rebuilt OEM turbo....so is that a K26/6 or K26/8 or???

normansan

Its the OEM KKK with a rebuild done to it.

Airflite40

6 or 8?

normansan

It's an '86 so I would assume it's a 6, but I haven't checked.

You probably have a cat, I'm guessing you have close to 250 rwhp at 13 psi, but I could be totally wrong

bunch

I would think at 13 psi with a 26/6 at best about 220 rwhp. But you need good tuning. I made with my 26/6 230 rwhp@15 PSI and with my 26/8 250 rwhp@15PSI.

Agreed... here's my dyno with the following mods:
Guru chips @ 15 psi
Test pipe

I have the same MAF.. Do you have a problem with stumbling/bucking ~2-3K rpm in 3rd,4th,5th? It runs great in boost.. just lower rpms off boost it does not like it. From my searches it appears that the "clocking" of the "stage 3" maf has a lot to do with it, but I have my MAF postioned the same as yours..

reno808

i bet its beccause of the "ARC"

3" Bullet Exhaust Tip & Lindsey Racing Fuel Pressure Gauge on Fuel Rail those sound give your around 25hp over stock

ehall

225hp

Get yourself down to a Dyno and find out for sure. It will also identify any flat spots you may have

ehall

I changed my mind. 682.364 RWHP

Sorry man, not that I've noticed, but I'll check it out once I get it off the jack stands.


You're using the equation incorrectly. 1 bling = 39.2whp. An exhaust tip is easily pushing over 1.5 blings itself. I can't be sure though because the total accumulative bling of my car is off the scale.


Sorry, I just copied and pasted the list of mods that the guy did on the car.
