What is the most boost I can run on my whipple? I am willing to run a higher octane gas. I don't drive a whole lot of miles and the gas is not an issue. Thanks for the replys.

I would guess 17, maybe 19 lbs but I don't have a Whippled Cobra even though I wish I did. :dunno:

depends on octane available to you.

i have seen as much as 23lbs from whipple most people dont run more than 17 for street use since most people only have access to 93 octane.

you can run 19lbs on 93 oct but you gotta drop the timing and your back to nearly same hp with more pressure on motor so why bother heh.

If you want to run race gas well you can run as much boost as your heart desires. From what ive read most wont recommend the whipple over 23lbs.

3.0 upper and 4lb lower will give you 21lbs at around sea lvl. Throw a 6lb lower on and you have 23lbs.

Next keep in mind if your at higher altitude or you have free flowing exhaust i.e. longtubes or non-catted mid pipes these can lower boost lvl's some. This is common to see with people running 3" exhaust.

Agree with blueblazes, I'd recommend running 21psi with conservative timing. If you don't drive the car all that much then it won't be an issue unless you just beat on it everytime you drive it.
A air/fuel gauge would be nice and just watch out for detination, make sure you have a good fuel supply and you should be good to go......MOST important is the TUNE. :thumbsup:

Thanks for the input. I'm probably going to go with 21#. Running higher octane fuel is no problem. A tank of gas lasts me a month

I'm Whippled and running 21psi w/ 17 degrees of timing. The tuner insists this is a very conservative tune given my mods.

BTW, my car makes just under 600whp.

most people agree that 21lbs on pump gas is a bit much im guessing your mixing in some 100+ octane or some torco maybe?

You can run low boost/aggressive timing or what I'm doing. You get the same result but what's key is it's safe.

Were I to tune differently the numbers would increase but, then again, mine is a daily driver that's done 10.7 at the track (10.1 on nitrous). I don't want or need any more. Hell, I can barely keep the 315's planted as it is. :D

I wonder how long that car you saw making 690 will last?

BTW, I don't see any mod info on your car. How is it you come by your expertise?
