Is higher boost really safe?

I plan on a 400WHP+ car on pump gas and 18psi. Lets just say I can get there on more boost...

NZ951, make sure to document things as you modify/test/dyno... to gain 66rwhp (400-334) at the same boost level will take some work and I suspect it will cost a good $ as well.

Yup, I have MANY dyno charts and saved fuel maps and temp data stored for each mod. I still have easy gains to get in a bigger exhaust (maybe 15-20WHP by the looks of things), then when back pressure is down, maybe you can or JME can whipe me up a 8SR/S3SR-19 or perhaps -21 cam. That should ad at least 20WPHP. Maybe a water injection kit to run more agressive timing and cool the charge ar down... and we will nearly be there... dont you think? I may need a big head though... jury is out on that one. Oh and I am working on a new intake...

The gains from the head will be obtained as soon as ST gets to the dyno. If I were you I wouldn't be too concerned about peak numbers, I would want a large area under the curve. If you noticed already, most 951s making large peak HP at lower boost have a peaky power curve, and not as much torque. In any event, as long as you have a game plan with preset goals you will be fine.

Well it sure is a good thing I dont mod my car to impress you then! Eh TimexNJ? (I think we should call you that now after your LR project blow out means you cant afford a simple MAF from a highquality vendor)

Just thinking about it TimexNJ, do you even know what Duke was talking about? Because
at that comment is very odd, I know you dont know much about cars, but still, very strange...
