Looking at getting back into the nitrous game again, car has a stock bottom iron 5.3/th400/FTI 3500 and was wondering what you guy's think about this setup and also if anybody is running this combo in a f-body!

Plans are:

Stock bottom 5.3
Ported 706's
LS9 gaskets
MS3 cam
Vic Jr.
Aarons elbow
90mm tb
150-200 shot

Also wondering if spraying a plate system @ the throttle body would be safe?

Or would it be best just getting the spray bar setup?

Thanks for any help!

 

You should be good either way. We like spray bars for the fact that they are not generic spray patterns. We set each bar up custom for every intake. This way we can flow check the pattern to make sure the nitrous is hitting the runners correctly.

 

Do you already have the cam? That is a smidgen bigger than I'd use in a 5.3...

 

Martin what would you suggest?

I'm not dead set on the ms3, if you suggest something better I'd go that route instead!

 

I'd probably do something custom since you're running a single plane and there really are no good single plane readily available profiles out there, which I plan on fixing soon with my own line of single plane camshafts.

I'd do something like 230/238 .614"/.612" 112+4 since you plan on 150-200hp worth of nitrous some exhaust split is needed, but nothing crazy as that is not that much nitrous in the grand scheme of things and doesn't need a dedicated nitrous stick. If you were running it on motor alone I'd want to see it on a 110+2 or 111+3 LSA, but you're not and it needs a little wider LSA, but still nothing like a true dedicated nitrous profile would have.

 

I sent you a pm Martin!

 

Sent you a PM back, and for those that are curious we ended up with a 231/240 .617"/.588" 112+4 profile.

Again if it was on motor alone it would have a 109+2, 110+3 or 111+4 in it, but since it's going to be sprayed slightly I widened up the LSA to spread the initial torque spike that nitrous has out some to the higher rpm regions which will only serve to make more horsepower and help get the heat out the chamber quicker and more efficiently while on the bottle.

 

Thanks again Martin for everything!

If anybody is looking for a custom grind dont hesitate to get in touch with Martin, great guy!

 

No problem Brandun!

I'm guessing the cam came in already?

 

Yes sir, it arrived today!

Can't wait until I get the car back together!

 

Good deal, can't wait to see it run! It should sound nasty with that cam in it!
