08 BUSA WITH NOS QUESTION

[knecum]

I'm building my first 08 with nos are you guys taking out the ti valves for this application? I heard you don't want to use them with nos with the heat.. I know i should know this already, but i like to get other opinions.. thanks..

Draco1340 has sprayed a 40 dry for two years with no problems

for more then that I thought you needed to do springs
wether or not the ti valves can take stronger seat pressures or not, I do not know

[jblankenship]

my 05 1000 with ti valves had heavy duty springs and a 100 shot. After that I went to stainless exhaust valves and sprayed 150. Then we bumped it to 180 and I burnt a piston. Valves still look great and so did the ti exhaust valaves that came out after the 100 shot had been on them for about 5 months. And stock I sprayed 50 for a year.

If it is a typical Steve Knecum motor, you shoudl probably take the stock valves out. Probably won;t like getting hit with a 300 shot of spray in top of a 1600cc motor

Yes my typical motor is a stroker, and this is a stroker , but he  is only using a dry shot maybe 60 hp, and as far as valves most of my motors are stock valve anyway..except the occasional 35mm ti head..and as far as a wet, i wouldn't spray more then a 100 myself

I was gonna say that
after talking to Mr Knecum at the starting line at Loring
I figured he would be more likely to build a 275hp motor then spray a 60 shot or so

rather then a 200hp motor then trying to spray 130 shot
