LS/Vtec on stock sleeves

-JE/Eagle combo 9:1 comp 81.5mm bore
-Stock cast head, Supertech Valvetrain
-Skunk Pro1's dialed in on the dyno
-LoveFab Ramhorn
-T3 6266 .82 backside
-2.5 piping into i/c , 3 inch upper cold pipe
-Victor X mani with 70mm cast TB
-255 LPH intank and 1600 old school low impedance injectors
-S300 on C.P.R
-93 Octane

18psi with the run stopped at 9100rpm.



RPM will be turned up at the track after a couple of shakedown passes. There's about another 10-20whp in the next 500 RPM....the plugs told me that i was at the edge of what 93 had to give.

Wow killer numbers for that boost and 93

No meth injection or anything like that?

Those are some of the highest numbers I've heard of on straight pump 93. Makes me wonder what the car would make on e85 or oxygenated and leaded race fuel

And meth is so easy!

Amazing numbers. Surprised you don't see everyone with a 500 HP honda. It's all in the tune. And I guess most people over build the motor for what they actually push it to.

Great numbers. Really really impressed. Almost as impressed as I was when I saw the RWD 500 HP Crx. Which is saying a lot!

LightningTeg

Nice smooth power

kyden

nice. my setup is pretty close to that but with 6265 makes 40 less hp at the same boost level.

MikeySpec

No meth or anything of that sort. The original plan was for e85, it might be out of the budget this year so i'm thinking some 110 will let us rev out a little more and bring in a few more pounds of boost.

Mase

Rev'ing it out higher isnt going to push the 93 octane barrier any worse. Your peak torque is where that lies.

Great powerband none the less. Reminds me of back in the day of 2004-2005 when 'they' said you could never reach 500 on pump on a b series. I think 4-5 cars I did around that year reached 500 on pump and not one failure.

Enjoy it.

Welcome back Mase.

Makes me rethink if I want to retune on E85 or go to 93 since e85 isnt available in my area!

Great #'s btw!!!!!!!!!!

sleepencivic

what are the AFR's? What kind of timing did the motor end up at?

MikeySpec

Under 12 and over 10.8 for AF. No special tricks on timing....not far off of what a basic pump gas car would be at for 18psi.

GJ Mikey.

Where'd the pro1's end up at?

MikeySpec

Advanced Intake cam around 4 degrees, retarded exhaust about 1

Uncle Dave

So good to see Mikey is still around always enjoy his threads and builds he tunes.

Mase

Muckman! Thanks, race season for both Grand-Am and World Challenge series is coming to an end, so I finally have some down time. Havent posted here in forever.




to the OP: if its running a true 10.8:1 (if the wideband is accurate) lean it out to 11.8:1-11.9:1 flat, it will probably smooth out the powerband even more. no need to run that rich, it will pick up more power.

2ltrgsr

good numbers... i have a build close to that with a 6266, made 515whp on 20psi with 93oct

MikeySpec

Notes taken, thanks for the advice.


I'll post something up when we get better gas in there.

I wish mase would bless my car with tuning. Him or J.Davis

speeddave

nice work, would love to see the race gas numbers.

h2.4

nice torque curve. good job.

crucian

Im sure that there are plenty of 500hp pump 93 cars out there. Not everyone post online. I have over 500 pump 93 but im a nobody on honda-tech, so why even post about it? lol

I'm well aware of this, my last built motor, a 2.1 liter ls/vtec wth custom everything from crank, to cylinder head, to cams, and intake manifold etc made almost 550whp on 93, no helpers

the trick is building a car that will reliably keep making that 500+whp on 93 and not **** the bed
