Saw this on the other forum and though people here would be interested. Here's the thread: http://www.svtperformance.com/forums...-manifold.html

I would have liked to see this comparison in TX with some 93 octane. Man these cars leave a lot on the table in stock form. Impressive gains especially for the minimal amount of mods.

No need for this info.

I usually take what I read off SVTPERFORMANCE with a grain of salt.

Track numbers do count more than power. But power does help you move around a track faster yes?

I say that about all forums. The meat and potatoes from that thread though(at least what I took from it) is that there IS a power AND torque advantage in the Cobra Jet intake manifold over the Boss 302 manifold. Say what you will regarding the other posts but, the dyno charts can't really be argued. Same day test, same mods on the same car. The CJIM clearly came out on top

You can have 500 hp and still lose to a 400hp car. Track times say it all

True. But this thread isn't about lap times, it's about the performance gains of a particular modification vs. similar part. Plain and simple.

It's a moot point really. You can dial in a car's system for a particular track and use the same setup and be less effective at another track. All things being equal, tires, LCAs, gearing, shocks, transmission, cage, harness etc, would you prefer to have more or less power than you have now?

I never said anything about lap times. Im talking drag racing. More hp doesnt mean faster. Is hp nice? Yes absolutely. Is it necessary? No in racing tq is just as important as hp. Especially drag racing. Id take a car that makes 350hp with 400 tq over 400 hp with 350 tq any day.
for instance my low hp 66 stang will out run 450+hp cars because it has more tq. Better 60' equals faster et. So hp is not always important

Are you referring to just Mustangs or cars in general? Ferraris have incredible acceleration while having very high horsepower and very low amounts of torque. Same with NA Porsches. This has been true before launch control too.

Hell, a Boss 302 is faster than a normal GT and the GT has more torque but less power.

This. I refer to it as the short bus forum.

I take things like suspension/traction out of the picture and use the one mile dyno down at Beeville. I really don't get all the talk about this manifold lately, I already proved what the CJ manifold would do way back in March, the car ran 152.8 to the half, and 180.0 to the mile. For comparison purposes latemodelrestoration's 2013 with a 2.3 Whipple ran 147.6/180.0, a TVS blown 2013 GT ran 145.0/166.9, 4 2013 GT500s at 142.7/164.8, 150.9/166.1, 151.0/176.9, and 147.2/177.8, plus 8 more earlier GT500s behind me too.

Are you comparing a boss with 3.73 gears to a normal gt with 3.31's. So yea boss will be faster with quicker acceleration. Torque is what gets you out of the hole on the track. Hp keeps you pulling. So back to your post yes hp is great but without torque your car will not 60' foot well, but pull hard with the high rpms.
Like wbt said dyno numbers dont always mean faster times.
I have several race cars and street cars. Only 2 ever seen dynos. 1 just cause we wanted to try it and 2nd I needed a dyno tune. The real dyno is in the track time

**Dominic Toretto** · 09-02-2013, 09:30 AM

Guys, the mod made more power according to the dyno chart that was supplied by the poster on the other forum. Unless he was lying about what mods were done with each pull.

I never said or implied that a car with more power will definitely be faster. There's tons of things that have to do with speed around a track. I never argued that. How is this so off topic now?

My question is they are saying there was a gain in midrange tq/hp over the boss. However, the stock Im already makes more mid tq/hp then Boss. So are they just getting that back and a little more on top?

**BLK2012GT** · 09-02-2013, 09:56 AM

Does it really matter if you lose or gain mid range power when you're racing you're above 6k rpms all the time?
