Currently the only intake manifold not sacrificing on broad torque curve and giving more hp than the gt350 im is the cobra jet im. It is however the most expensive out of them all, not just the im but modifications made to fit the im and special cai's.

Who the heck is 'racing' below 3,500rpm?

>3,500rpm, the GT350 has WAY more torque than the GT.
Yes as stated above we are talking up to 6 to 6500 rpm range. Again this is not using frp tune, it is any other aftermarket tune on a fbo stock im vs fbo gt350 im. I wish it was just up to 3500 rpm but its not!

Actually, the gt350 is faster than a gt with gt350 intake. We did a number of both drag and roll races, with the gt350 winning, by a small margin each time. The gt gets the jump, but the better gearing and top end of the voodoo motor proves to be faster. We even switched cars to take the driver differential out of it, and got the same results.
I think the GT with the GT350 mani would also need E85 and LT's to beat a stock GT350.

It might need tires as well, depending on details of the competition.

Ohh no you got that wrong, not below 3500 rpm, lets say 6500 rpm! Compare a full bolton stock intake mani with a gt350 intake mani, didn't you guys see the dyno results? This was done way back in the day.
Below 3,500rpm, a stock GT makes BARELY more Tq than a stock GT350 -thats the point, when you're bragging about the GT having more torque, it does not in the useable power band. Above 3,500rpm, the GT350 blows the doors off a GT with a lot more torque.

Stock vs stock yes, but a full bolton gt with stock intake manifold especially with 3.73 gears manual or auto, will always walk away from a stock gt350. Maybe after a half or a mile gt350 might catch up and pass it due to high end hp.
A "full bolt on GT" with 3.73s makes less power and torque than a GT350 that also has 3.73s. I don't see your logic...:confused:

Yes as stated above we are talking up to 6 to 6500 rpm range. Again this is not using frp tune, it is any other aftermarket tune on a fbo stock im vs fbo gt350 im. I wish it was just up to 3500 rpm but its not!
So your GT350 friend will shift at 6,500rpm for you to make it more "fair"? The GT350 has more displacement, bigger cams, and a better flowing head. It'll be hard to match.

For whatever reason its a lot closer than you'd expect. To my knowledge no stock GT350 has broken into the 11's without DR's. Here's my full bolt-on (catless LT's, exhaust, CAI, and Lund Flexfuel Tune) GT running E85.

At a better prepped track, looking at the traction issues I had around 40mph, I think its safe to say that's an 11.8-11.9 run @ 119-120mph on street tires.

No idea if I'd walk a GT350 or not because I've never lined up against one, but I do think at very least it'd be a tight race despite what the dyno says should be happening.

What tires? What are you making on the Dyno?

GT350 with a tune & cat deletes on stock PSS (which suck at the strip): 11.68 @121mph:

Continental ExtremeContact DW's, to be honest at our power level all street tires are gonna suck unless its a well prepped track. No idea on the dyno numbers, I'll be able to tell you in a few weeks but it'll be with a GT350 manifold in addition to everything else.

Very nice run, I know the GT350's have the trap speed for 11's all day, its just getting enough traction to do so. EDIT: Also your car sounds sick, no doubt I love the stock sound but I like it even better with the cat delete.

Not my car. Was a 10 second Google search. Looking forward to your Dyno results!

You have so much miss information! I suggest you read the V8 sections and builts! 3.73 mustang gt has shorter and more aggressive gear ratios compared to a gt350. 3.73 is only the final gear ratio. I suggest you do a search for gt350 vs cj manifold and click on the svt performance website. They have a full comparison including stock im!

On top of that someone already laid out torque and hp graphs for each gear on top of each other in the v8 thread. We have seen full exhaust and tune getting into consistent 11.8's, and that car was not an auto. Usable power can be from 2000 rpm or 3000 rpm up to whatever your intake manifold allows. This can be 6500 rpm for stock or 7250 rpm for the gt350 intake manifold. If you are only considering 6500 to 7250 rpm as usable rpm then i suggest you invest on a crotch rocket!

Sorry, I don't know who "she" is.

The GT has slightly shorter gears and also a much lower redline, so you really need to look at the whole picture (total torque at the tire -which takes power, rpm, gear ratio, final drive, wheel diameter into consideration) to be able to compare them. You can't blindly say "shorter gears = faster" when there are far more variables in the comparison between a GT & a GT350.

Who is 'racing' at 2,000-3,000rpm? "Useable powerband" usually refers to the RPM range for the best acceleration -which does not happen between 2-3K rpm :thumbsup: I never said it was between 6,500-7,250rpm, you seem to have missed the point.

When a GT350 shifts at the stock redline, the RPM drop is usually to 5,500-6,600rpm depending on the gear. For a GT, it's 4,600-5,500rpm -which are good ballparks for each car's 'useable powerband'; although both pull well from a little below that, it's not down at 2-3K.

If the GT350's torque band down low climbed rather than leveled, dipped, then spiked, it would be an 11 second car without trying and the trap speeds certain show it. They would be even higher if it weren't a bogger at 2500 RPM. But it is so...

Launch at a higher RPM. Work the clutch.

lol, if only it worked that way. Trust me, it doesn't.

If there was any car that could make a believer out of a driver mode off the line, this one is it.
Sounds like a lack of talent Phil. This ain't no supercharged car with a flat 500lbf-ft torque curve from 2K-redline. Try launching a V8 M3 with even less torque or any 90s Honda :thumbsup:
