I have not been on an official dyno yet but I do have Dynolicious on my iPhone. After about a 45 minute search I found the actual drivetrain loss % and I weighed the car at a weigh station. the results......

 

Car 1988 rx

weight 2500# without driver

drivetrain loss 25%

 

test parameters 0-60 and HP

acceleration G .53

0-10 1.18

0-20 2.19

0-30 3.10

0-40 4.64

0-50 6.02

0-60 7.80 seconds

peak HP 157 (this is flywheel hp)

 

Modifications:

 

Ford SVO TMIC

boost controller set to 12 Psi

TWE DP 2.5 inch

2.5 inch front pipe, cat, mid pipe and tailpipe

Heres my dyno run from a couple of months ago.

 

TD04 turbo and WRX TMIC.

2.5in exhaust. Cats still in.

Spyder intake with K&N panel filter.

MSD coil and Iridium plugs.

Boost control set at 12lbs.

102 octane fuel.

XT6 flywheel.

 

As you can see, my numbers started dropping off bad after 5k.

It needs bigger injectors and engine management.

yours is wheel HP correct?

Of course, all dyno runs are AWHP.

Add the 25% loss for the drivetrain and its around what you came up with.

But take a look at my torque.......171 between 3.5k and 4k.

Btw, weight doesnt account for much on a dyno run.

using a gtec type thing you need the weight. btw wheel hp on mine comes in at a rather pathetic 118 but torque is in the 140s. Not too bad for stock turbo, injectors, intake and headpipe.

Gtec isnt going to be very accurate.

Get it on a dyno if you want to get closer.

Even a dyno isnt 100% accurate.

true I was planning to have it on rollers Sat but the shop was unexpectedly closed so I took a stab with Dynolicious. I will have a dyno sheet soon I hope.

my engine management keeps hitting fuel cut. is there something I can do or buy that will keep it pulling even on cooler days? I have had to turn the boost down to 10psi to keep from hitting fuel cut.

Your boost gauge may not be accurate, fuel cut shouldnt kick in till you get over 12lbs.

Theres a way to fool the ECU by adding a circuit to the MAF.

thanks.

I changed boost gauges from the VDO that came wiith the car to an autometer (lower limit just 15psi vs 20) and sure enough 13.5psi so I turned it down to just 10 and everything is happy.

where is there an AWD in Charlote? May need to drive the big bad Brat from the Rock to seewhat it will pull, LMAO.

I know of three and perhaps a fourth AWD dyno in Charlotte and Concord.
