Re: H2b info
 

Only way to know is to dyno and run it.

Re: H2b info
 

It'll make around 200whp. It should also run somewhere in the 12s if you can drive.

Really hard to say though, only way to find out is run it on the dyno and take it to the track.

Re: H2b info
 

Around 200whp.. you should be able to hit mid 12s..

If you don't have the flywheel yet, i'd invest in something like a Hondata S300.. you will get more out of that with a good tuner. Also you're set up for future upgrades.

Thanks for reply guys.....pippen you think with s300 i will get more whp than p28 ecu chipped or socketed???

Re: H2b info
 

It should make the same power on either one as long as the tuner is good.
The S300 just has more features.

I prefer Neptune RTP, works great and it's a little cheaper than the S300.

Re: H2b info
 

How you launch guys??? What rpm and slicks pressure??? With preload or dump the clutch immediate????

Re: H2b info
 

Always preload on radial tires. I haven't run slicks before so someone else will have to chime in on that. I preload and launch at the RPM that is best for my engine/suspension/vehicle weight/track prep/track temp/clutch/tire pressure/tire compound, based entirely on how I felt it do on the launch previous. That's what I'm trying to say, your question can't be answered with any degree of accuracy unless by someone with your EXACT same engine/clutch/hp/tq/vehicle weight, EXACT same track, EXACT same day.

Just go to the track and launch it. If you spin and go nowhere, launch at a lower RPM next run, lower pressure, etc. If you bog and go nowhere, launch at a higher RPM. It's that simple.

Re: H2b info
 

Always preload. Less stress on the drivetrain.

As for S300 or Neptune.. go with whatever your tuner has more experience with. My point is that you should be able to get more from your ride.
