I already have a built motor but I am putting a ported eaton back on my truck... I was thinking about getting a designated fuel system(no fuel issues) and spraying the truck with a big shot (175-200... maybe more lol) HAs anyone else sprayed this much on a lightning? what kind of times did it run and how did it run? was it a ***** to tune need sum help here fellas!

I don't think anyone has really successfully run a big shot like you're looking at doing. I don't see why you couldn't with the proper hardware, and it looks like you're going to be doing that. I think the ported blower running 12 lbs max would be the way to go. Maybe even a little slower. I don't think spinning it fast is the way to go at all.

I've seen a KB 2.6 with a 175 shot. It made a lot of power. I think as long as it is tuned properly, and your setup is sufficient as far as fuel supply, I wouldn't see anything wrong with it. As far as more than a 175 shot, I don't really know. I'm not a big fan of nitrous. Getting back to the truck that I saw, he was never able to use the nitrous because he had too much power with the tires on the truck matched with the boost the engine produced.

"Built engine" does not mean you can spray big nitrous.

What are your ring end gaps?
What are your piston to wall clearances?
What are your rod and main bearing clearances?

These things matter when it comes to making big power with nitrous.

Been several people run larger shots.........

Ive ran up to a 200 on a nozzle, and only took my nitrous plate to a 150; the plate on the 150 was more potent than the nozzle on the 200.

If your wanting to run a 150+ shot look into a nitrous plate from this guy:

Trick Performance Products Turbo Kits Front Mount Intro-Kit

Tune......get the tune right on blower; pull a couple degrees of timing out run GOOD fuel. Then adjust the jetting on the nitrous system to finish up the tuning. Really simple actually.

thanks casey! so u would reccomend a plate for a 150+ shot... i will have to look into that. I planned on running a dedicated fuel system( kinda like the nitro dave setups) and I was gonna run it with sum c16.... i figured with a stock ported blower i could drive the truck around and have fun then when i wanna get serious... open up that bottle lol.

Casey02L

Yeah.........I dont like running much over 100~150 through a nozzle; they arnt very efficient and cylinder distribution could be an issue.

Dedicated fuel system for the nitrous is a good idea; run a regulator on it and you can use the FP to adjust the fuel sides "jetting"

Onlything I dont like, but some people do it is the race gas for the nitrous fuel and pump gas for the engine.......... the 2 fuels have different specific gravitys and do crazy things in the combustion chamber.

Bad as L

You have to get the exhaust out of the motor as well....I would run a 1.5" exhaust valve....16 to 20 degrees more exhaust duration....the biggest header tubes available (1 3/4") at least 3" exhaust with no cats.

And like Casey said you have to make sure the nitrous is getting to the cylinders evenly....you need to bypass the intercooler and go direct port.

This what I would do for a BIG shot.....as well as all of the other things mentioned.

Who?

Casey02L

Me and Booger have some of the fastest 1/8th ET's out of the streetable blower/nitrous trucks (dont think he has his new setup running yet); several JLP trucks; Sal use to use some big shots and set records at the time with them; then there have been others over the years who have used 150~200

I guess if you havnt tuned it then it hasnt been done right............

Confusing me with your gal pal JJ

Just wanted to know whose running big shots - I really don't think 150 is a big shot and I haven't heard of anyone running anything scary.

lightningkylej

I remember a couple of guys running over a 300 shot from back in the day. I believe Sal (PSP) was running about a 350 shot when he snapped the crank back in like '01 or '02.

Casey02L

Not my pal......

I dont think 150 is that big either.....Booger was playing with 300's and I think a few 400's. There are more....not everything gets posted on the internet.

Dont forget CHIKIN1 back in 01' I think?

damn, now that is alot of nitrous!!!!

FAST-EDDIE

casey I have a Zex kit that Im going to be running with my new built engine and the 3.4 whipple do think that it will be safe to run a 150 threw a nozzle
