I probably shouldn't of just made a blanket statement like that. Without knowing what the cam timing was before it would be impossible to make a judgement call on that aspect. I'm of the mindset now though, that a good N/A cam with some attention paid to the amount of nitrous that will be put through the motor will run just as good or better than a "nitrous" cam that has a huge I/E split and a overly wide LSA.

I wouldn't really expect to see a Mozez head motor with a really early exhaust valve opening event, as the exhaust port on that particular head flows a significant amount of volume. It's all relative to the combination. That said though, you can take a lot of exhaust duration and stick a tight lobe separation on it and make the exhaust opening event later than a cam with less exhaust duration with a wider lobe separation.

What do you take from the dyno graphs I've shown?
Smaller cam compared to?

I see the same thing all the time tuning. The big donkey dick cams never seem to run as fast.

I seen the same thing with my nitrous cars

Any dyno graphs you can share and specs? It would be cool to compare notes.

The cam that was in it.

I dont get caught up in dyno numbers, I hardly ever dyno anything on nitrous unless its a very small shot. I tune 99% of them at the track.

Not concerned with the numbers, just the shape of the curve. If the power peaks and then falls on its face versus holding that peak power out over 300-400rpm it's going to be faster at the track if you can shift it later to take advantage of it and have the top-end to take advantage of it. Having a 400rpm window of peak power versus 800rpm has got to be faster at the track unless you've got a 4 speed lenco set-up and a 5.13 rear gear that only drops 400rpm on the shift. With a powerglide that drops over 1000rpm on the shift the wider the powerband the faster the car will be.

Totally combination dependent of course.

Everything we have with alot of nitrous all have glides. Without a loaded dyno I dont even bother anymore since it doesnt load the car hard enough to get good tuning data.

Yea we have a 224XLC so we can vary the amount of load we put on the rollers. Really nice feature to have for F/I and nitrous.

I think you guys should sponser my forged 347 6 speed car to promote your cams.
My rear hatch would be yours to letter up

That's a really good running car you got there man! I wish we could give out free stuff, maybe one day soon we can do something like that. Car moves out for sure though with the 6 speed.

I met Jonathan and his dad way back in like 2006 or 2007 at the GM high tech performance track rental/photo shoot .

**** forreal?!?! That was a long time ago! His car has changed a lot since then as you can see by the dyno graphs, but at that time it was the fastest n/a ls motor in the country.

Give me a call one day at the shop and I'll see if I can do anything for an old friend of the shops. :-)
