Cobra jet manifold vs Gt350 manifold

[rozay]

You think gears have any affect ? I'm with more engine load at 180mph vs his 150mph

The GT350 with the stock TB is the way I'm going. I already have all the other supporting mods.

How is the drivability of the car with the GT350 intake? Who's car is it so I can PM him and keep from derailing this thread??

He's not on the forum sorry

Gears do affect dyno numbers but the lower the gears the lower the numbers... so having 3:73's didn't help his numbers at all.

^This. You can clearly see a peak on your graph, on his, it abruptly ends at 7500. This thing will rev to 8k or damn near it.

You're right! On my friend car on pump gas it peak at 7300 but loose only 1.4 HP at 7400 . I am sure on my M6 car with my better exhaust, different tune and small vct adjustment it will hold power a bit more but even if it drop it still a easy 7800-8000 rpm shift car.
Thanks to Rozay for the post !!

Thanks for the reply! Both cars are generating some power and thanks for posting this! :cheers:

You left that out that your numbers were std correction on that last post. I didnt want to assume that its what you meant. I apologize

[MENTION=13019]UPRSteve[/MENTION] itll be interesting to see how the gt350 does against holleys sniper manifold

I though 3.73 would make more power than 3.31 do to I'm under more load

Are you both on stock injectors?

All other things equal, what's the power difference between [a tuned] E87 vs. E90 vs. 93 octane standard/pump?

I realize the deviation between the 3 may vary as power and mods increase, just wondering how that played into the dyno numbers.

BTW, thanks OP, this is a really terrific information. It's looking like the GT350 IM/adapter/stock TB, with intake, tune, (injectors?), headers, exhaust in a number on a number of different cars/dynos has put down 520-530-ish engine, and with the extra RPM ceiling, would be a blast with the 3.73s in the PP!

[edit] Looks like a couple of dyno results I was thinking of were actually the CJ IM, so I guess we don't have a notable sample of GT350 results.

Not enough people have dynoed with it to know. Only [MENTION=10666]Nick@JDM[/MENTION] and [MENTION=15682]sandeale[/MENTION]

All these high dyno numbers from the GT350 mani still haven't seen one go fast down the track

Did anyone with a drag setup went down the track on a gt350 mani?
