Well........I'm going to hit up the local track this weekend for the last street legal event. Ive been running a 100 shot for a year now and the car is doing great, but I think I want to step it up a notch. I have 2.5 gallons of VP motorsports 103 to use and I will mix it with 92 octane gas and maybe a NOS octane booster that I have kicking around.

As for timing, I wont be retarding it at all. I've read alot about guys running 150s on stock timing.

so what do you guys think.........should I go for it??

 

Run the VP but leave the octane booster at home. I'd be a little iffy running a full 150 with no timing retard. If you have the ability to retard it before going out, I would. At least 4 deg. or so. Hope you have at least drag radials or ET streets or have fun laying down the rubber. Hehe. Good luck.

no you shouldn't. you should do 200 like me. i do not do any timing retard either. and i run 93 octane only.

 

I do infact have ET streets.........thank god.

I think Im gonna go for it......a guy only lives once

 

Go ahead and do it. the 103 will be just fine, dont mix the booster in. A overkill on the fuel. As for retard the 103 will help a little.

 

Much less his motor

 

I think the Ol LT1 can handle a couple passes with the 150 shot. If not...........383 here we come.

 

i have run 150 and 175 on my LT1. the 150 i didnt pull timing and ran it a few times on pump gas,most of the time 100-104 unleaded.
The 175 i pulled 2* and ran the same unleaded,never had a problem.

 

The only thing im worried about is the fuel pump...........but, it should be ok. Just got it tested a month ago and pressure was bang on.

 

your stock fuel pump should handle up to 450 hp..

 

Go for it.

 

Do it!! I was running the 100 shot and ran 8.04 in the 1/8 with just CAI,4.10's and a flowmaster muff. (drag radials also). Put the 150 in and went consistent(sp?) 7.85@92mph. It would spin bad, with that mph if i could have got traction the runs should of been 7.30's or so.(i think??) Anyways, i prob. ran 20 bottles through it with no probs at all. By the way, i didnt pull any timing, pcmforless programming

 

Well.........I went for it. Car took it NP, but mister clutch had something else to say about that. The car smoked the clutch all the way down the track while I was on and off the gas going "wtf?????" to myself, lol. I even tried the 100 shot after and it just slipped and slipped and slipped.........ya, you get the point.

spec stage 3 here I come..............

ill get that 11 sec timeslip yet.

 

Im on a 150 shot with advanced timing, but i have 109 VP in my nitrous stand alone fuel system.

No problems here, I'll let ya know how the 200 hold up.

 

your joking right ?
