I decided to try a couple of new mods today. Didn't touch the tune. I've got three EvoScan v.99 logs, each with one 3rd gear WOT pass on level ground. I'm hoping someone can can plot the HP/TQ curves for comparison purposes. The baseline was done a week ago, but the temps were about the same as today. The run with the test pipe and the run with the test pipe and FMIC were done on the same day and the air temps on the logs look close. It was a little cooler out though when I did the runs with the FMIC, but not dramatically cooler (maybe 5-10 degrees).

Here they are:

BASELINE w/Random cat and stock FMIC

BASELINE w/test pipe and stock FMIC

BASELINE w/test pipe and bigger FMIC

I turned down the boost controller just slightly with the test pipe to keep the peak boost the same (22 psi). I didn't need to touch the boost controller for the FMIC.

Any help would be appreciated. I know that the tune is too lean in places and it needs some work. That's next. For now, I just wanted to see the comparison without touching the tune.

Thanks!

Can you repost them with the column headers still in place, preferably in an actual excel spreadsheet (save as .zip)? I don't mind doing it, but I'd lke to do it with minimal work on my part

 

Hopefully, this works. I put them into one spreadsheet as three different tabs. The column headings are in there too.

Thanks!

 

I thought that spreadsheets.google.com was pretty cool so I had to try it

 

What are your mods? Are you still on the stock turbo?

 

For power stuff: HKS 264/272, WR8 turbo, ported manifold/turbine, tubular O2, Buschur turboback, Buschur UICP, Niseil LICP, EBC, Full Race FMIC (added today), 93 oct

 

your car weigh less than average RS? I would guess about 320 on mustang dyno for log #3 for a typical evo weight

 

It has a minibattery, 16 lb. wheels, aluminum coilovers and no spare in the trunk. Other than that, it's pretty standard with the bumper beams, full interior, etc.

 

OK, your graphs were way high for a stock turbo, but look about right for what you have. Here is what I got:

Run 1:

Run 2:

Run 3:

 

Thanks!!! I'm a bit surprised to see the difference in the FMIC, especially up top. I didn't think it would make much difference. I paid very little for it, so I figured it was worth a try, but it appears to be worth it. The test pipe really made a difference in the mid-range.

Hopefully I can run a little more timing with the TP to get better spool-up. I've always felt my car was really laggy for a stock-type turbo. It feels fine in the car, but it just looks laggy on paper.

 

Good call. My 04 RS weighs significantly less than the 3500 lb (with driver) number that is often used to calculate power. The curb weight stock was 3025 and many simple mods drop it further.

EDIT: mine is just a tad over 3100 with me in it.
EDIT2: corrected curb weight from original press release.
