More Power!

And really, if "bang for the buck" is the major issue as far as performance goes, nitrous oxide is a far better value than plenum porting work and headers. I'm not necessarily advocating that in lieu of the engine work, because you have the complexity of the nitrous injection hardware, the hassle of refiling the bottle and lack the coolness of a modified engine *but* if initial-cost-per-performance-gained is the benchmark: nitrous is a better choice. A properly installed and calibrated nitrous injection on a 350 inch LT5 can get you to 550hp with ease whereas you'd never see that from a 350 with engine mods that also had reasonable drive ability.

Please note this isnt for your 13,530 Mile garage queen. You can blow and engine quickly. But NOS systems have advanced over the years to improve safety, and the decent bottom end of the lt5 might be interesting. Have started looking into this and mat startup a small websitr dedicated to this.http://www.holley.com/index.asp?division=NOS

I won't disagree with you about the NOSs bang/$.
However I will add that lady Nitrous is a dangerous and exciting vixen that if handled correctly in controlled conditions can perform wonders.
But, should you handle her incorrectly, she will cost you dearly.

NOS is nice, but it's better to be blown.
Twin Turbo for big power, the only way to go.

getting blown will always give you the permagrin:)

TC,

I'd have to agree. With NA and Turbo, the power is on tap always.
NOS needs planning and prep.

Speaking about that has anybody seen an update on the twin turbo project?

[Jim Nolan]

Which twin turbo? When I dropped off my '92 Aaron at
SGC was working on one. I believe it was a black '90.

[GOLDCYLON]

LOL at this point any twin turbo project. I know Ron Hanselman in Nevada was working on one before he retired from the Air Force.

[Kb7tif]

Will keep you updated

[TommyL]

I would like to go twin turbo and an auto trans...I think that would be a blast and something different. NOS for me, would be track only and these motors are far too expensive to play with that. If i was going that route, I would buy a different car to modify for track only.

[Kevin]

how do we feel about n2o vs nos?

:worship:


Love it, NOS is a brand name. N2O is nitrous.

[FU]

If anyone can find an excellent way of delivering N2O into the LT5 speak up. I'm very interested.

Trying to break the right hand side now?

Trying to break the right hand side now?

One of the u-joint cap's on the right side had a small crack in it and had no grease.
The right side was well on it's way.

What's the current status, send a pm if you want.

Didn't one of the big N2O companies make an LT5 kit back in the day that was hooked into secondary operation and whatnot? I seem to recall seeing a used one for sale in the not too distant past, I think it was around a 90 shot or so delivered by two nozzles?

It is hard to find that kit.
But by today's standards a good stand alone system should be readily available.

NOS kit# 5172 It's more like 125/150 shot.

I run this on my 94. Went from 280rwtq to 480rwtq @ 3000rpm.

Damn Kevin is that on a low compression rebuild or stock power plant ?

that was nos

[Polo-1]

That's on the stock 350. It has headers/corsa's/rc injectors no port work.

It's more like 292rwtq @3000 rpm. 484rwtq small jet.

I ran a bottle before I dynoed ( dont do that ) When I finally made it for a dyno it was 13.2 /13.4:1 A/F ratio.

[Aurora40]

I thought that was weird too, but then I noticed the rpm. I think he's saying @ 3000 rpm was where the big gain was, not that 292lb-ft is his n/a torque peak. Presumably it continued to rise until the mid 4,000's or higher.

[Polo-1]

Yes

Peak torque N/A is 348-351 between 4200-5200 range.

On the N20 it was too lean to finish the run. I have a new chip from Marc hope to go back for full pulls and play with the jets more.

Peak torque on the N20 was 484 but had to shut it down @ 3700rpm.

Keeping in line with low rpm, HP was 225/227 N/A and on the N20 330-334 at the same 3500rpm.

These low rpm # compare to a cammed 415 ci. at the same rpm.

Bottom line you can have some fun with the N20. Just make sure you dyno it to watch your A/F ratio to be safe. Or buy a wide band and gauge to tune safe.

And Yes the 402 I'm building for this car will be on the N20 also.

[diamond zr1]

never enough,right Kevin? Had my fidanza on the dyno last week@ 5lb boost was pulling 580rwhp@ 5000 and breaking the tires loose/decided not to waste the runflats or increase the boost/t turbos are bad.

[rkreigh]

wild wille had a shinoda bodied stroker LT5 with a NX direct port nitrous kit (also of course Julio and Kurt)

the NX single and dual nozzle setups work pretty well too.

the NOS kit is DRY and relatively tame, I'd stick to 100-125 shot as it relies on the injectors for additional fuel

here is my suggestion on nitrous, be very careful, validate bottle pressures, window switch, and check the system often.

all it takes is one failure of the fuel side and you will pop a motor

I'm old fashioned, but with the cost of rebuilding lt5s, I guess I'll save nitrous for my old chevy BB engines.

no doubt there is bang for the buck (in more ways that one!!):mrgreen:

I talked with him on Friday, he might be able to help. Hope So!

[Zr1 Destroyer]

With all this n20 talk does this mean somebody is going after nitrousjunkies 10.20 record? I don't think his new 427 is going to need any n20 though.

:rolleyes:Julio.....lol!!! Neither of those guys could make a full quarter with their direct systems.

Watch some of those videosOooooch!!!! I had a buddy do that in his nova last year.......he turned his nitrous on somehow when he was waiting to run at the track and he went up to do heat his tires and kaboom.
