Track day tomorrow... 21lbs of boost?

[my98gsx]

I have a 98 GSX with a close to stock block ( commetic head gasket and ARP head studs ), 650cc injectors, walbro 255, a large front mount, and a logger. I am going to the track tomorrow and today i turned up my boost to 21lbs... Im staying rich on my fuel but due to my internal waistgate on my 16G i am hitting 24-25lbs of boost spike for a sec or two.... Does anyone think this is unsafe to run on the car? Every other 1/4mile run i made was set at 17-18lbs and i only ran a [email protected]... I really want to break into the 12's this year but i dont want to BREAK my car doing it.... thank you for your help

Tuning is everything. I have a completely stock 7 bolt engine, even down to the stock studs and HG, and I run 24-26 psi. If your car is tuned well, with NO knock at all, it's perfectly fine. You just have to be careful and make sure you have a good tune. Running rich isn't always enough, you can be octane limited too, it won't matter how much fuel you throw at it if you run out of octane. I run alcohol injection to be able to run that kind of boost. I would throw in some race gas if available. When you do a log, make sure you're getting at least 16 degrees of peak timing advance.
