what kind of gas to use before racing?

Well im gonna run this guys del sol si all he has is an intake and he thinks hes the shit.This guy wants to run me for 100 bucks.I just wanna know what kind of gas i should use and should i use octane booster?

89 octane unless you have a turbo, supercharger, nitrous, or high compression (10.1:1+), and then use 91+ with octane booster.

octane doesnt add any power, it resists knock. using high octane fuel in a vehicle not designed as so will make it lose power due to the fuel not igniting well enough. And also, octane booster will boost the octane sub 1 level. i.e. 91 octane with octane booster makes about 91.5 octane

I dont know about octane booster but for gas, just what you use for everyday driving I think. Higher octane rating only means the fuels ability to resist ignition.

Jo, I uZ 105 octane race gas in my D15B2 with some octane booster and IZ was runninZ 15.7z Biiaaatch!

Use the same damn gas you always use.. Low octane, cheap-o rama..
Unless you have advanced timing or something and if you do I assume you already know to use a higher octane fuel.

what do u have done to ur car that ur gonna beat this guy?

u dont have a weight advantage and he has more hp stock... i hope he doesnt have any work done.

Don't bother wasting your money on higher gas...and if you have enough money to waste on expensive gas just get cheap gas and whatever u save send it my way :-P

A crx hf is so much lighter than a del sol

yea what you use normally will be fine But i know this'll start a debate. I use 87 for my STD normally. But if i run 2 tanks of 93 or 94 the smog clears up a bit so only for smog do i swap to the higher grade.

ya, just use 89, cause if i remmember right you have the d16a6 in your hf and that should be able to take the del sol si prety easy

Well i have a d16a6,si tranny,exedy clutch,intake,exhaust,header,shortshifter and my car weighs 1860lbs.He has a del sol si with intake and exhaust hes just a really good driver.

Your car weighs 1860lbs!? Did you have it weighed? What the heck do you have done to make it that light? Thats nuts!

crx hf are the lightest honda made like 1850 for an 88 and like 1870 fo the 90-91 ive been told....

Are u guys talking about the Del Sol that comes with 125hp from the sohc engine (d16z6?) or the Del Sol that comes with the dohc B16? Sorry guys, don't know much about Del Sol's, lol.

The del sol si d16z6 127hp. Dont worry with 89 octane ull whoop him as long as you get a good start!

Run 10-30% Toulene and advance your ignition timing :)

Yeah yeah get some drag radials while your at it...gut your whole interior...and carbon fiber everything, lol. Im just playin around, I think you should have him.

your car ain't a funny car or a nascar, jus use your everyday fuel dude. don't get to carryed away with trying to figure out what gas to use to race a everyday car

I thought the Del Sol Si's came with the B16 just like the civic Si's?

Dont listen to them . . . . :naughty: You need some Nitromethane! Get yourself a mix of 90% nitro & 10% methanol or alcohol :icon16: Your engine may only last a couple mins(if that) but hey it will smell good :icon16:
