boost and spray

[heyitsmepugsley]

im new to forced induction and have very little experience with nitrous. but im putting together a gt40 top end on a freshend up stock block 302 with a paxton blower, my question is can i spray it too?

Sure ya can Idk what the consequences are though lol. Someone with more knowledge will chime in I'm sure

I think you can as long as its tuned for it I wouldn't try it with no tuning

Probably not for long on a stock block. If your running lower boost pressures...maybe get away with a 50 shot on top of it. Probably pickup a good bit do to the intercooling effect from the nitrous. But your playing with fire on a stock shortblock...very high cylinder pressures. Run a colder plug like a autolight 103 with a tight plug gap. Run the best fuel you can get when you spray it...at least 110 race gas.

Yes it can be done. The question is why? You can make enough power with a blower or nitrous to break a stock block, you don't need both to do it. So, I think if you had a good aftermarket block and rotating assembly, and were using a blower and wanted the intercooling effect or a little more power it might make sense. But short of that, you really don't need it. Also, tuning is an obvious concern. It would be very easy to make costly mistakes with that setup.

Exactly! You can make over 500 horsepower with just a novi 1000 on a stock shortblock. There are alot of variables when running spray, even by itself. You would want to make sure to always keep the bottle pressure the same on every pass so the tune is spot on.

well the only reason i want to do it is because i want to go fast. lol i want to build an 11.50-12.00 street car and i just dont know that my setup is going to produce them numbers.

What he said! I am making 473RWHP 445T on a modular three valve with cams, LT's and 9.5 psi on a twin screw. Whatever you do take it to a reputable tuner and get it tuned. I hear Adam at S/M is making quite the reputation for himself. He has impressed quite a few of the heavy hitters on the site here with his excellent tuning skills.

You should be able to get that with just blower

Fast is a relative term. These days, getting a street car to run 11.50/12.00's is easier than it ever has been. You certainly don't need two power adders to accomplish it.

[heyitsmepugsley]

haha i was just a little curious. but i sure do appreciate the input guys.

[Adam@S&MMotorsports]

Which Paxton blower are you running?

[heyitsmepugsley]

Sn89 its the older blower but i sent it down to cundn and had it rebuilt last month.
