i have a 416 ci ported l92s looking to swithch it over to race gas or maybe a mix, is there power to be found doing this?? and what kind of race gas vp ??

 

If you don't have a need for it you may not see any added power. What is the compression of the motor (static and dynamic) and how much cam duration/overlap are you running?

 

My L92 416 has a static compression ratio of 11.85:1 and I have no issues with Amoco 92

 

the motor is 11 to 1 new cam is a 251-259 661-664 lift on a 112

 

only thing that running a race gas might let you do is run a little more timing safely, if you want to try some thign like a 105 unleaded and retune the car for it, go for it. But with 11 to 1 comp I doubt that it's needed.

 

all right thanks

 

just wondering i have a 416 bout to be done... what are your specs and how much rwhp did it make?

 

when it was 6 speed it made 505 whp

 

what tranny is in it now and what did it make? Curious because your times aren't that far off mine.

 

I have a 12:1 static, 8.9DCR 346 that needs 50% 100 octane race fuel to keep it from knocking, and that's with only 25 degrees of timing, in 25 minute road race events.
If you can run 28 degrees without knock, don't waste your money on expensive gas.
PS. I'm building a L92 415 with 7.9DCR so I won't have to buy race gas @ $8.75 gal.

 

made 445whp

 

Get a standalone....for a nitrous kit.. that is a good place to put race gas.... otherwise just put 93 in the gas tank.

 

How much timing are you able to run on pump gas? I ran my 12:1 L92 setup on 93 octane but could only add 24 degrees of timing. At 11.3:1 I was able to run 29 without KR - still on 93.

If KR is limiting the amount of timing you can run to below 28 degrees, I'd think about running something higher than 93 and more timing if your looking for best results.

My $.02

 

exactly what mine made when it was first put together, and it ran the exact same times too. I bet teh car weigh's around 3625 or so huh

 

somewere in there i thinking its around 3575 with me in it
