quick run down of the setup...

stock sleeve lsvtec
ctr cams
sls ramhorn
60-1 stage 5 ex wheel .82ar
3'' exhaust
91 octane

my question is im aiming for around 450-500whp for the track..so insted of draning my 91 octane out and putting in race gas everytime i get to the track...could i just get a water/weth kit for this power level? it would be alot easyer lol...any input would be helpful...
thanks

 

Race gas. Unless you do direct injection nitrous style with the meth it will almost undoubtedly feed unevenly in the cylinders because of the way our manifolds are.

 

i see meth injection as another variable to go wrong.

what sovietday said makes a whole lotta sense also.

 

ok..ill just stick with the race gas...another question i have is,does race gas go bad after sitting around?..if i bought a barrel now and didnt use it till spring would that be a good idea?..or just wait till im ready to use it to buy it?

 

it will go stale over time.

 

I'd also opt for the race gas. If you were hardly pushing it on pump gas and wanted a little more leeway, i'd say go for the meth injection, but for your situation, race gas is really the only good option. Do you have E85 in your area?? That'd be a cheap alternative to Race Gas...

 

ok good..ill just wait till im ready to use it
thanks

 

E85 is a great option if its available. At the 500whp level, you would need to be sure you have enough injector, fuel pump and fuel line capacity. E85 uses about 1/3 more volume so it would require capacity similar to running 750whp on gas.

 

no e85 isnt avalible around here..i wish it was tho...ill just use some c16 or q16....rite now i have 780cc injecters running stock fuel psi...what is the whp limt i can go on these?
