Dyno shootout Ported TA vs X factor Singleplane

Hence the methanol injection and lower compression for the turbo specific engines. I'm confident I can hit 800 hp and the same tq using my budget 398 hp build with a street cam!

 

Multiport injection, Hershe rods, and the block girdle and I'll be hunting for the 1000 hp benchmark.

 

that would be nothing short of spectacular:TU::3gears:

 

Nice! I am extremely excited to have a chance to test this intake. Thanks Sean. BRING IT ON!!:3gears::beer

 

Way to go you guys. I hope to see some of this stuff in person some day soon!

 

I'll have to give Jim a call tomorrow. Those numbers are low.

 

The reason it says 455 is that I forgot to change that in the program header file. My mistake. We did quite a few pulls on this engine with both intakes, the engine did go over 550 horsepower . The thing that impressed me was that with the single plane, we had more instances of being over 500 lb/ft of torque than with the dual plane. this manifold really works upstairs. What we were mostly looking to do here is compare the 2 intakes. The 2 inch spacer did not necessarily make any more peak horsepower on the single plane, but it seemed to broaden the horsepower curve. My feeling that the intake is well designed and will do what it is designed to do, make killer horsepower at high rpm. In the tests I ws not able to run the TA with no spacer as the carb fuel line ran into the manifold, So we ran with a 1 inch spacer. It is really difficult to try to run very low rpm power pulls on my dyno.

 

Thanks Jim! Any final peak HP figures?

 

THANKS to Mark, Sean,Rob, and Jim for all your efforts. I can't wait to get mine Mark. Man you got to be fired up about those results. Awesome job!!!! I got some custom rods and pistons that will test where that intake wants to fly. I've been shiftin at 6000 rpm and now I see why it noses over beyond that with the TA intake.My cam should be good to around 6500 rpm. This is unbelivable progress for the 350 guys. Thanks Troy

 

Thanks! I expect to have it wrapped up this week. This intake is certainly not going to limit your hp rpm peak. Time for some healthy 11sec timeslips!

 

maybe even tens when you get the alki kit and a manual boost controller mwahaha

 

Actually I was referring to Troy's 12.04 run. I hope to see 11's with my turbos later this year. 10's are a ways off. Too many weak links in the chain to hit it that hard for me yet.

 

well looking at his eta he might be in the tens or very close to it if he can get the traction!

 

Man I cant wait to get the Skyhawk running....

 

yea me too, as i want to see some buick videos!
we need a buick video network lol
and remember, ford sucks, mopar swallows, chevy spits, and buick blows...by everyone!

 

OK racers, one serious question. I am learning so if the question seems childish I am sorry.

I absolutely love the HP and Torque numbers you are getting with the intake, but have a question. My car is 100% street so I would like to pull the power curve down about 1000 RPM. I realize that I will be giving up some of the upper end power, but what is the chance of making it to 6000 RPM before you get to the next stop lite. I want to get the power range in the 1000 - 5000 RPM range not 3000 - 7000.

Can I do this just with the CAM or what other mods would I need to do this. Goal here is to be into the power from the start to get off the line, not the top end.

Thanks,

 

There are many things that contribute to power band. Rob's engine has much bigger a cam than you would want, which also contributed to the high rpm powerband of these test.

We hope to have some additional tests done on a street engine to see what happens. If nothing else, I'll be putting one on my car and can discuss how its low rpm response is.

 

Not childshish, its an honest question.

You would be better off with a stock intake for the 1000-5000 powerband you are looking for in my opinion.

We wil be doing some testing with mildly cammed 350s to see if the X factor can outperform the stock intake from idle to 6000 so the verdict is still out on that one.

The above tests were done with a 1000 cfm carb, big cam ect ect. Next we are looking to investigate the lower rpm capabilities of this intake on a mild engine. More dyno tests next week on a roughly 350hp 350.

 

I had been having dialogue with Jim Wiese about building my 350. I was going to use an 800CFM Q-Jet, have the heads ported, bigger exhaust valves and the 10 - 1 pistons put in. TA284-88H CAM. With headers he thought 400hp would be attainable. If the X Factor would be better I would be all over it like stink on $hit.

Looking forward to seeing what it does with a street engine. The difference is I will have higher compression then what you will be testing at so the head work and maybe the intake would have a bigger difference.

 

Very impressive. Now we gotta start worrying about guys with 350's. I guess I better start saving those engines too!!
