How much boost on these dyno graphs?

How much boost was being run on the 100 and 93 octane graphs above? Thanks

Another question...

That's rear wheel horsepower?

Or, is it computed to show power at the flywheel?

If that's rwh, it's really good!

huh?

Sorry, I don't know much about dyno numbers... what does "corrected" mean. That doesn't mean that it is trying to interpolate what is actually at the flywheel, does it?

Thanks for all the responses fellas. I dynoed my dawg (BPU) last weekend and put down 405 to the wheel - thats why I was asking. But for some reason I'm only running 15lbs of boost. I gotta find those damn boost leaks!!!

quikturbo - do you think I would lay down 440 if I found the pesky leaks to run 18-19lbs?

I dynoed on a hot engine at 370rwhp/375 on my straight bpu auto on 93 octane and ran a 12.21 at the track (100 octane) how do your track times compare? if your putting down 440rwhp in a 6 speed what numbers do you see at the track?

picturemerollin: not sure about what amount you'll put out, ever car is different. However, if you do infact have a boost leak then your numbers will definitely increase, especially if its a large boost leak. Good luck finding any leaks. You should be running more than 15lbs of boost. One other thing, reset your ecu before running as just a preventative measure for limiting boost.

SilverTT:
here are two time slips from the track when my car was straight bpu with drag radials
I'm car 18

best trap 121.97mph


best et


those runs were on 100 octane

Hey QuikTurbo..

How much boost were you running on those timeslips, what octane, and what exactly do you have in place for BPU mods...exhaust etc? Also, what is your launch technique at the strip? Thanks

well, at the time those passes were made my mods were

bcc, rmm dp, RM exhaust, hks intake, custom air box (like the "MaxAir Box"), and headlight out, also a new rps clutch, and hks evc ex. Tire pressure in the nitto dr's about 18 to 20spi, and 100 octane. Boost was around 19 psi
I'm still trying to get more consistant with launching. Originally I was dumping the clutch (used to my old mustangs :)), and only ended up bogging. I started to slip the clutch and started netting better 60fts. I think I bobble the rmps around 4500 rpms and then slip it. Granted its harder on the clutch.

emkay, its really difficult to gauge how much your car will put on with mods, every car is different.
I've seen bpu cars pull 380rwhp all the way to 450rwhp.

only true way to tell is to get it on the dyno

not sure if you've come across www.mkiv.com , however, that site will help you out tremendously.
good luck
