13.5:1 compression anyone else

[INFANTRY RACING]

anyone running this in their 400s. i am ordering up my piston monday and was just wondering if anyone else is running this high of compression. what octane race fuel you running.
where can i get the flex steel gaskets and for how much.
anyone figure out heavy duty head studs that don't cost 80 buxs.
any thing else i should know?

13.5:1 that is very high...i would run 110 octane or higher tho

[hondafreestyler]

that is hella high

[BIGRED400]

I hope you got a good strong rod / crank to push that compression or else :rolleyes:

[JDiablo]

snap....lol i would return that piston and get a lower compression one if i was you

i have a 12.5 to 1. i didnt do the bottom end and it broke in 2 races once i got the crank trued and welded i havent had a problem i run c12 to play ride and use ultimate 4 when i race and iv been fine for a year of racing

[JDiablo]

still you have 12.5 this guy is going to be running 13.5:eek2: ...if you are going to run that high in which i don't reccomend you should get a better,strong crank,and rod

[JD400exrider]

Order up a rod with it. Otherwise you might be looking at pocking out your side cases. :eek2:

[INFANTRY RACING]

ahhh..i have a stroker crank thats welded with heavy duty rod and all new bottom end bearings

[Chef]

Don't worry about it. You should be fine with the aftermarket rod and welded stroker. I run a little bit more than 14 in mine, and no problems yet...besides the whole keep the front tires down and the rear tires hookin up...:cool:

[INFANTRY RACING]

[Chef]

I had custom studs made, and I'm not sure of the material. As far as the head gaskets, I think they are custom cut steel ones. Thats about all I know.

how bad is it on the starter. burn any up

It is pretty even on the TT track with a 428 Banshee until about 70. Then he starts pullin me a little bit. As far as off the line, if I can get a good start, I can beat pretty much whatever shows up. I have outpulled ESR330's many times.

Its not too bad on the starter, It doesnt take real long to start, basically hit the button and it starts within 1 or 2 seconds.

Post some pic's of that BIG DOG:D

Chef-did you get your piston from Curtis Sparks?
Is he the only person you can get a 92mm piston from without getting one custom made?

Also-did you run it on alcohol?
What results did you have?
Did it stay together?
Thanks .
