Hey everyone. Ive got a quick question.
I just got done putting my cam in a couple weeks ago, and its going in to get tuned on monday. Before the cam, i was running a 100 wet shot for about a year, with the stock fuel pump, with no problems. Now heres the question. i have a walbro 255 sitting at my house, but i dont think im going to have time to put it on before monday, since i have to work fri. and pretty much the whole weekend. Do you think i will be ok running the stock fuel pump with the cam and 100 shot, or even a 75 shot on the dyno so i can have the A/F checked on spray? Like i said i was having no problems before, but i dont know if the cam is going to make a huge difference or not.

P.S. i havnt sprayed the car at all since the cam, just because i didnt want to risk it without a tune, since im sure the A/F is all over the place.

Thanks for any help!

Start small and watch the AF...it will tell you if you are running out of pump.

Even if your AF is not an issue on the dyno get that 255 in the car, it is not doing you any good on the shelf

 

Oh it will definetly be going on the car within the next week or so, i probably wont even spray it until i get it in after the tune, just because i dont wanna chance it. I just dont know if im going to have time to get it in before monday.

 

TTT for the night

 

When i went and had my car tuned with the 100 shot the tuner told me that it was in my best interest not to shoot the car until i had a fuel pump.He said that the car was way to lean and that the stock fuel pump just would'nt support the nitrous

 

anyone else have any thoughts??
