I have a 98 and i heard that the 98 fuel pump will with stand a 150 shot, My question is, if i use 100 + octane gas, will i be ok?

I sprayed my tnt 150 shot once this weekend in 85 degree heat and 92 octane.This was for the 1/8 mile.I usually mix 92 and 110 50/50 no problems yet.

I have been researching this & right now I'm thinking the racetronics kit for $250 because it's a real plug & play. There are a little less expensive options out there but they always seem to involve a little hacking.

Exactly, no way I would chance spraying a 150 on the stock pump. Especially if the jettings are for rwhp. A new Walbro by itself is about a $110, and as mentioned the complete Racetronix is about $250. That's cheap money to help save your motor in the long run.

Also, I don't see how 100 octane will help you run a 150 with the stock pump. With the 100 octane you can run alittle more timing but if the pump can't keep up and the car leans out big time, I don't think it would help you all that much.

sweetness! i think im going to invest in one!

Anything else i need to buy to have it work, or is it complete?

Yes ractronix is very nice that is what i have ,its the best looking pump you will ever not see once you put it in

The 100 + octane would be to counter act not having the ability to adjust the timing.

With my NX MAF kit, I was told that I could run up to 150 with no problem on the stock stuff. That came from NX

pump was holding with the 150 shot pretty well..with the 250 it started fallin off a little at the very upper rpm range
