Default c6 200 shot off the rail ?

hey guys i have a 06 c6 ls2 a6 im thinking of spraying the car. i already have an NOS big shot kit. ill be spraying with a single fogger till i get a plate. walbro 255 in the tank. any one sprying this big of a shot off the rail? car is cai tsp headers full exhaust timming set at 23* 24* and of course cooler plugs. with the single fogger will it flow 200 hp? i might just run a 150 threw the single fogger till i get a plate. it will end up a progressive kit once i go 200hp

side ways mounted bottles why not ?
im thinking on mounting the bottle side ways because of the ttop mounting anything i should be worried about?

Yes its fine to pull 200 off the rail with your setup. (Close to stock.) If you are worried about any kind of pressure drop you could always install a fuel pressure safety switch.

what about the bottle mounted sideways people say its not good. id say the only reason would be when running low on n20. other than that is there any other down fall?? i never let my bottle get empty i usually fill when half way to keep max pressure.

Just make sure you mount it so the siphon tube is pointing downwards and about 35* rotated toward the back of the car, so that the momentum from launching pushes the nitrous towards the back of the car and up the siphon tube, we have done a dual bottle setup sideways in a C5 before like this with no issues.

I have a very similar question spraying 200 off of the rail.

1. Could a stock LS3 fuel pump with a large cam making 480rwhp N/A spray much off the rail with no fuel mods?
2. If fuel mods were needed, would a boost a pump or raxetronix harness be able to get me where i need to be without adding a Dedicated Fuel System. (which will be done down the road)

I'm going to say no to number 1. This really only works with close to stock applications.

2. A hotwire/boost a pump kit might get you where you need to be, or you could look for an aftermarket drop in unit.

If you decide to go with a safe system, one of the nice things about that option is that its easy to install, gives you a completely separate fuel source for the nitrous system and it gives you the ability to run more timing by putting race fuel in the tank.

Thanks,
Garrett

thats how i run mine , no problems yet. 10.0 so far on a 150 with cam off the rail. but got the new nx kit and went to a standalone for 200 hit this year. i was out of pump tho.

to answer the question on a 200 hit with cam. my car thur a auto made 472/442 on a dynojet. on a .062 jet tuner had to pull 11* to keep from running out of fuel . mine was running lean. with things being that close i wouldnt advise a 200 with cam. gonna run a 0.72 jet for a bit then if needed go to a .078 to get the ls2/3 bottemend c6 record. so those supercharged fools what a nitrous car can do. NX to the top.

Dekan, I've seen a few of your threads on cf. Very impressive times. So you've been running the cam and 150 shot making over 600 on the stock fuel system with no issues Running off the rail?

my camaro had no issue , but my vette did. could be cause the vette is older and has 4x the miles and still orginal pump might be getting weak. but it was going lean a bit. i have 2 buddies that run 150 off the rail and have no problem with a cam. but its def pushing it . just watch and be careful.

I have sprayed a 16X shot off of the rail in my 04 gto at the track. I trapped 132. I have sprayed a 200 shot off the rail on the dyno.

Made 440 on motor 625 on 200 shot.

Hold on a sec here, you ran a 10.84@128 with a 2008 ls3 c6 auto with only
headers, cai, tune, 3200 fti , ky speed cam, and stock suspension??

That's ******* STOUT, whats your rwhp off the bottle? and what gears? 2.56??

and then a 10.03 @ 138 on a 150 shot????

I'm buying a base 08-09 1LT auto car FTW....total sleeper machine if it can bang 10's off the bottle.

Well, the cam will definitely give away your chance of being a sleeper haha. It's not uncommon to see a bolt on cammed c6 in the 10s though. You get the right converter on the auto and it gets awesome gains. I have just a bolt on ls2 auto (stock cam) and pull 10.9s @ 123, I put 400 RWHP down. I just put nitrous on but I haven't tuned/dyno'd it yet but I'm hoping to have my bolt on/nitrous c6 in the 9s.



Quick Reply: c6 200 shot off the rail ?
