New dyno numbers!!

[Jay_pee99]

Here they are!!! I took the kinetix off and put the gutted stock manifold on literally right before this run, so i dont think the computer had adapted just yet. But here they are anyway!
254.80whp 253wtq

Mods?

[SKarpenz]

Yeah, thats impressive. Mod list?

[Puppetmaster]

I think his mods are similar to here.

New PB 5.5gen manual!

Nice numbers JP, wish I could have stuck around longer to see it and dyno myself. It was good meeting you again.

[nismology]

^ Oh ok, cool. Thanks.


OP: You might gain a few extra ponies by sleeving that gutted cat.

[Gooey]

nice numbers jp! Your A/F got a lot better. Cant wait for the coming track season.

[ajcool2]

Congrats man. Tell Jaydubb to post his numbers too.

I not quite sure what that means? Smooth out perhaps?

Thanks man, Good seeing you again too!! The run included all those mods plus a fidanza flywheel.

So whats next? Do you plan on adding phenolic spacers, larger throttle body and MAF?

[DonSupreme]

For me thats some crazy lean A/F.

[AJ's Silver CL]

Those are really good numbers !!!! Why didn't you run with the kinetix manifold ???

[DasYears]

cause it sucks?!?!

Hehe, no its not, look at my dynos, my last NA dyno was with a/f mostly at 13.9-14.0, lol. He's still pretty rich on the midrange IMO. VQs can run surprisingly lean relative to what others tune for.

That pretty garbage manifold? Yea meng that thing isnt worth the cost. Gutted FWD IM flows just as good for FREE.

[Ghase]

Too lean, upgrade your fuel pump and add an adjustable FPR and lower that A/F to around 13.3 or so. Just to play it safe......

Your right about running lean, cause my last NA dyno my car was around 14.5 at redline (195whp with auto), and boosted I run 10.1-11.4 redline (FPR needed). And that POS manifold= Adds Butter to midrange but overall topend power is almost the same as the OEM manifold.... Hooonda like hp gains $799....

You'll get owned on my last setup that made 311whp on 9psi.... Now I'll be pushin 15psi......

I already have a Super afcII but didnt have much time to tune due to the amount of people dynoing.(Over 20 people)

Wow, 13.9-14.0. Has anyone else heard, or agree with this?

[pimpin02max]

Nice numbers man, now I'm guessing on this though that your SAFC-2 has been used or is your car still untuned?

I think SR20DEN has gone up to 14:1 before. Also, one of the Z's that was there with us had his AF flat at 14 from his Osiris tune.

[nismology]

14.0 is a bit lean for me. That's the thing with a product like an AFC though. The leaner you go the more timing advance so people are willing to go super lean to eek out all the timing they can get. Best case scenario is still aggressive timing with a a richer a/f. AFR is a better safety margin than a power gainer in the n/a world.

[NmexMAX]

I shoot for 14.0. Makes more power up top. There's a fairly strong 4th gen in the dyno sheet section that also does that.

Indirect timing effect.





Oh, and the smoother curves that I see tend to have reasonable a/f's. The ones with jaggies at high RPM are lean (timing being pulled). For a dyno run or a quick WOT burst it's fine, but I still maintain that the best case scenario is a safe a/f with aggressive timing. That's if you're 1337 and can change a/f and timing discretely.

This IS the dyno forum.
