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.

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.

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.

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.

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!!)
