Is it safe to run a supercharger and nitrous togather on a basically stock Ls1 motor. Seems like to much boost. I see some guys doing it.

 

Many guys use N20 as a "cooler" to lower the intake temps.. ~50hp shot. There are a few out there going after a bigger shot.. It's all about having the engine setup to take it... and a VERY good fuel system.

Moving to Forced Induction section.

 

Like WIL said, many people use nitrous, as well as other things to lower intake charges. (i believe co2 and water as well are used, with water helping to reduce detonation i think...dont quote me on that)

Lingenfelter ran it on his 298mph Firebird back in the days when he did top speed runs...lots of turbocharger guys do it on their intercooler setups to lower temps. But like WIL said...motor has to be built to handle it. On a 'basically stock' LS1, i wouldn't recommend it. Maybe a blower @ first, then upgrade when the $$$ comes in.

Other then that...i would not sugguest you run both nitrous + supercharger on a "basically stock" anything...

Supercharger/nitrous on stock bottom end.

I lifted a head doing this with a 50hp shot and Vortech. The car had stock head gaskets. I'll be spraying the same shot with the 409 motor and ATI F1. These heads _should_ stay down <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

If you are going to run the ProCharger I dont think there would be a problem running a 50-75 shot on it. But I have heard nothing but horror stories with the vortec and the spray. But the HorsepowerStore here in Plano,TX has a very fast ProCharged and sprayed Formula as posted above. I have taken many rides in that car and it F#$king moves.

There MPH doesn't match their HP.
There TQ #s don't match with Nitros.
There TQ should be alot higher than the HP.

How long have you been running this set up? Any problems, how about the 6 speed? Right now I wouldnt mind running a smaller pulley and getting a LS6 intake. Is this on pump gas?

I run 93 octane. My timing peaks at about 24 degrees. I'm putting some stage III heads and the 02 LS6 cam in this weekend. There has been some debate wether I would gain anything from this. I guess we will see. The power has been down all summer do to the hotter weather. But now that it is cool It is back. I'm also thinking of spaying a 30 shot sneaky peat. Lets see what the bottom end can really hold up to.
OH by the way, my bottom end is stock except for the Katech hard rod bolts.

If you put the smaller pulley and intake on watch your a/f raito. When I put the smaller pulley, intake and headers on. I was running really lean. 14.2:1. But I didn't know it until I dynoed with the wide band. Before the dyno I was shooting oil out of the dipstick tube all over the hood when running it hard and high rpms. I found that I had detonated due to the lean condition. I had broke two pistons middle ring land. Also lifted the heads and blew out the head gasket. Thats when I put the rod bolts and studded the heads. I then put in 50lb injectors and had ed wright tune it. Now I'm running too rich. But have not had any engine problems for about a year now.

30thta436:
Congrats!

Is that a V9 G-Trim?
Looking at the new C5 V2 SQ kit that just came out over here...

 

Yes

 

My stock 346 short block has run 10.30 at 133 in Vegas (2700 da) with 6 lbs. boost and 100/150 dry shot, and the car weighed 3600 lbs. I have complete confidence that it can run in the nines, at or near sealevel, with this setup. However, I also agree that the stock short block will not live long under such abuse.

 

Stealth.. What is your setup? Your mph should have been higher with 10.30's..

 

Actually, we concluded that the ET should be lower with our 132.90. For example, there a number of cars on the Low Et list that high 9s at ~132. Vegas is at 2,200 ft, so our car would probably run high 9s at sea level.

Our setup on that day was a 346, Comp cam, Vortech at 6 lbs., 150 dry shot, Moser w/3.73. We're building a bigger motor, much more boost, more NOS, T400, etc. which might run high 8s at sea level.

 

I'm an avid worshipper of stealth... <img border="0" alt="[worship]" title="" src="graemlins/gr_hail.gif" />

Steve- Where do I send my fan club application to?? <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

What do you guys think of spraying a 50 shot of nitrous to the intake plus a shot directly on the intercooler(s) just to cool the air more??? Is this possible? I remeber the sy/ty guys would do this to cool their IC.
