Thread: finally raised the boost

just went and dynoed, it made 280.5whp @6000 and 270 wtq @ 5200 rpm @ 16 psi.

car is pig rich it drops to below 10 afr after 6200. the dyno guy said i could pull alot more power out of it if i could tune the fuel.

then as im pulling up my block, i go to depress the clutch cable and SNAP ! im thinking the clutch cable just snapped but its od ass i can grab the tranny arm and move it back and fourth freely...

new clutch cable today or tomorrow and if thats all good im going to get some bc3's , springs and retainers to increase my top end and max power.

Nice, I think that's pretty much in line with the numbers I was making. Not surprising since we have similar setups. You should be able to pull some fuel out with the afpr, but that would be across the board.

Did they give you the Dynojet file? If not, call them up and see if they'll email it to you, and you can download the viewer from the Dynojet website.

I'm not surprised your cable broke, that ACT is stiff as ****. As far as moving the arm, if it's just a few inches, and without any resistance, that's just free-play.

the car was rich from idle basically lol, im thinking i may get a calum realtime ecu. or maybe jwt ****ed up my tune or my 740cc injs are just to big for the rest of the set up.

yeah the dyno dude was like wtf is wrong with your clutch, im like its been like that always lol. yup i guess its free play, same thing happened to my all motor nx but the clutchs free play is the clutch peddle and its loose and it will just drop down and sit right before engadgment but it does shift fine... what a nightmare lol. i miss my automatic honda LOL.

chris **** didnt go to well with joey, he told me he lost his job .

Get the run file, and send it to JWT. They may be able to do something for you. I think if it's rich across the board, you're safe to adjust the AFPR.

I just checked my Dynojet runs, and using SAE correction, mine made 286whp @ 6100, 274tq @ 5200 and the AFR was 11.8 @ 4800, down to 11.3 @ 7100.

HELL YEAH! Can't wait for the pictures!

Very cool Rich.

If you clean up the fuel you will get some more out of it like Chirs mentioned.

We put together a T-28 car a few years back and at 15-16 psi we made 301 whp. So I say you are right on point. You are some S4's away from making well over 300 whp.

Who is going to come out to Kentucky and try their chances is what I want to know?

Nice numbers.

This is all on a regular t-28?

If so, congrats!

thanks guys, car has s4's with a regular t28. now its time to upgrade things.
