Anyone care to see dyno sheets?

[dvcrogers]

I will get 2 pulls tomorrow. One with the LA3 and the other with the LA2 w/Superchip. I will post them if there is interest.

I'd be interesting to hear about the results, specifically the difference between the two. Try and make the 2nd run equall as possible to the 1st (i.e cool down the IC w fan etc) such that the only differencecs would be the different ECM's.

Good luck & have fun!

Sure,
Love to see them. I always like seeing that stuff.

I'd also like to see what else has been done to the car ( for HP wise )

[dvcrogers]

I will tell you all that I know.

It has the obligatory K&N
water cooled T3
E6 manifold
Wrinkel bent 2.5 inch exhuast with 1 chamber Flo Master(read VERY crappy)
#35 injectors
TC intercooler
Aeromotive AFPR
and a "fish tank" valve

Now about some issues:
It needs the gasket between the turbo and manifold (thats the reason for this dyno session really-exhaust is coming)
It builds boost VERY slowly compared to before the gasket blew out.
With the LA2/chip it does not idle well. Still drivable but not by much.
With the LA3 it idles good, but the pull or "hit" is nowhere near the LA2 combo.

It has run 11.96 in 1000 FT this Summer-temp was 95 and humidity was 98%(Arkansas weather). That was at a track altitude of 367 ft.

Oh, it is a slapper car with 3.73s

Did I miss anything?

High 11's are excellent times for the mods you have. Dyno runs should be very intresting.

[dvcrogers]

That high 11 was in 1000 ft.

low 14's in the 1/4

[Will]

oops, 14's are still good.

[dvcrogers]

The numbers are in:

let me break it down:
I made two pulls starting with the LA3 computer. I was able to have a 30 minute cool down before I made that pull after my 20 minute drive there.

Run 1

peak power was 183.35 @ 4600
peak torque was 217.27 @ 4400

HP on that run was real flat from 4400 to 6000
(well both runs )

Run 2:

Swaped out the LA3 for the LA2/Chip and was only able to give a five minute cool down

Peak power was 180.64 @ 4600
peak torque was 212.46 @ 4400

Pretty much a wash out.

Run 1: 50.42 Degrees, 29.77 in-Hg, SAE .096
Run 2: 50.82 Degrees, 29.79 in-Hg, SAE .096

Let me be the first to say that I now need to go back to the track and run because something is "amiss". I run consistant 4 MPH higher in 1000 Ft with the LA2/chip combo but you cannot tell that here.
Maybe that missing gasket is screwing that up, or maybe because I lowered the fuel press. from 49 PSI (where it was when I was making my track runs) to 39 PSI as of today that messed something up. Who knows?

I will try to post a scan or pic or the runns this weekend!

dvcrogers-What psi of boost were you running? And what kind of dyno were you running on? Just curious. My car has similar HP to yours.

I had a turbo flange gasket blow out while on the dyno. I made about 12 pulls while tweaking FP and timing and every run the boost would come on later and later. It finally got so bad that I was getting max boost at 4100 RPM, and then we figured it out It did not seem to hurt the top h.p. numbers, but it sure softened the boost hit.

I was running 18 psi on a Dynojet. I dont know the model # of the dyno though.

I was not seeing full boost untill 4500 rpm or so.
You're right about the peak numbers, but this thing feels like a go-cart trying to build up some momentum.

Before the gasket blew, I was seeing full boost at about 2500.
I really didnt think that the HP would be so flat, but I guess thats the nature of a turbo.

[dvcrogers]

Here is the run

Enjoy

Not the nature of a turbo per say, but it is the nature of this particular engine. I've owned a bunch of turbo cars, and none of them had the torque curve peak early and drop steadily with RPM's like the ford 2.3 turbo does. Your graph looks very typical.

Thanks for posting the dyno sheet.

[dvcrogers]

BigBlue:

It was my pleasure.
Anyone else have any dyno sheets they would like to share?

[SVOeric]

if you show the fuel curve, I'm sure you'd see it drop off the bottom of the chart (rich) from about 2590 - 3500 rpm..


There are other dyno sheets posted in the members area,
