Dynoed the FD for first time
 
I did my first dyno on the FD today up at Mainstream Performance in Metro ATL.
My mods so far are:

Wallowed stock DP

-2.5" mild bend cat-back with can muffler

-removed air-pump

-Blitz SUS intakes

-Efini 99' y-pipe

-MBC's


I just put on the MBC's and fiddled with them for a while. I finally got the boost between 10-11psi all the way to redline. I didn't have enough time to get rid of my 12-13psi transition spike.



I made a peak of 249whp/241wtq at the transition spike.

It made 245-248whp from 6400-6800 at 10-11 psi steady.


I was surely impressed! I was guessing 230-240max.

with a guessed 20% loss then I would be about 310bhp. I had 38psi in the rear tires (stock 93' wheels). The temp was 65F / Hum. 15% / Baro. 29.5.


I WILL have a dyo scan as soon as I move the computer back by my printer.

thats some pretty good #s for your setup

cloead 02-06-05 10:47 PM

With a 3" dp and 3" catback (stock main cat still in there) I put down 285rwhp. 11psi


Edit: I don't know why I posted this. I'm sorry :( Superbowl party im not thinking right. I thought we had similar mods or something.

Dude, you are so full of it....What next, your gramma put down 480 on nonsequential stock twins?


















Just fucking with you pookie :*



Actually I had a similar run with my first setup. see my mod list for first dyno run....

I think he meant hollowed?

RotaSpinna69 02-06-05 11:23 PM

Those are nice numbers. Gives me an idea of what i'll be making. What 1/4 mile times?

1234rotor,

Would you tell me what rpm each dashed vertical line on your graph represents?
The rpm, boost and AFR relationships of the stock ecu are of some interest to me, even though your car is slightly modified.

thanks

They were using a tailpipe niffer for the dyno day. The shop owner said that the reading should be right about 1 point leaner with that reading.

cruiser 03-06-05 04:01 AM

So you were actually running high 12 AFRs ?
OMG... dont do it :)

When I dynoed with a high flow cat, I had a wideband connected before the high flow cat, my afrs were about 0.5 lower than the Dyno's AFRs (which were from the tailpipe).
I also noticed your air pump was not hooked up, I assume this would affect tail pipe AFRs as well.

No No No.... I was really in the high 10's.... the catalytic converter makes the tailpipe readings approx 1 point leaner than they actually.... sorry, I should have clarified that more better.

WOW good stuff man!!! I'm interested to see what my dyno numbers will be this summer
I'll have these power mods:
HKS FMIC, Apexi pfc, street port, ported turbos, ported intake manifolds, non sequential, 3" straight through exhaust ad some small stuff liek new plugs, wires, custom open air intake.. blah blah blah

How are you liking the dual ARC bov's?? off of ebay?
