The cometic head gasket would replace your stock head gasket, it's the same thickness as stock so it won't lower your compression, it's supposed to be better than the stock head gasket though. Then you can also add a 0.80 spacer under the cylinder to lower your compression so you can safely run more pressure. If the engine is coming apart I would definitely add the spacer and replace the stock head gasket with the cometic gasket.
well it was dynod with and without water. lost about 5 hp with water but probably did 20 pulls without water and didn't have a problem. There are guys running 10lbs without water and no problem. Granted they run either straight race gas or a mix.
ouch man... sorry to hear that. It just doesn't make sense that 6psi blew your h.g. unless something was wrong.(octec @ Mar. 22 2007,10:51)
new update...
they fried cylinder 2 & 3 very badly and wrecked the jugs. headgasket was intact. there's severe peppering of aluminum on the cylinder head
Thank god Richard had all the parts I needed to fix it.
turns out the boost level wasn't checked and it was running closer to 12PSI !!!! or so we think..... the hp rating that I posted was at 60% throttle at 9000rpm
to make a long story short this isn't exactly a cinderella story of mad street power.... just an expensive lesson for the bike not being checked out thouroughly before tuning it.
it would've been cheaper for me to ship my bike down to Richard to tune as now I've got a $3500 repair bill on my hands.
Thanks to Richard for making my life a bit easier I'm not spending the 5K that the dealership wanted to fix it.
