I've Read Alot Of Post About The Elbows Robbing Power But Does It Make That Much Of A Difference If Someone Were To Go FI?

^ No, it's actually the opposite. I've seen a lot of people lose power on FI setups by switching from an elbow to a 4150 / 4500 style throttle body.

^ I Won't Be Switching From An Elbow To A TB. I Was Asking About The Power Loss If I Were To Put The Elbow On Top Of The TB. How Much Power Would The Elbow Rob If Any At All?

I honestly wouldn't say crazy numbers down low, but you'll notice low-end loss with it. My mechanic told me he gained almost 22 RWT below 3500 by switching from a elbow to a ported LS3 intake. I'd do a 4150 TB if you want to rev to the moon and make a higher peak number as well. You might sacrifice some low end, but i think you'll be happy with it vs an elbow sir!

Thanks. I'm Tryin To Get To The 1000+HP Range. I'm Just Tryin To Do Something "Different" I Haven't Seen To Many People With The 4150 Or 4500 TB. Is This Because They Aren't Good For The Power? I'm Hoping I Can Go With Something Similar To This Setup...

LSX 427
Ported LS7 Heads
Super Vic
4500 Accufab TB
F-1C Procharger....

You Guys Think That Will Get Me Close To Where I Wanna Be?

A carb hat

I'm going to find this out, on my setup with a super vic. There some diffrent carb hats. The cheap spectra, procharger, and the $200 Extreme Velocity hat. It looks like a cly head runner with a big bowl, I've read guy on YB test them and say its the best, but thats on blow thu setups. Not draw-thu NA. Crab hat I can use a maf with for inspection (NYS) Also would like to run a air pan, that I think would make the most power.

You should not lose any low end with a 4150 TB but gain a **** load more over the elbow setup.

I run the chepO (spectre) hat on my NA setup. For NA it works as good than with the 4150 TB running open without it. If i had a FI setup i would run the Extreme Velocity hat with out a doubt because of the curved conture of the back of the hat that will allow the air to turn down easier over the spectre hat. NA wise the air is not moving fast enough for the spectre hat to be a problem. I was actually very impressed with the quality of the spectre hat when i got it,it's not that cheap when you pick it up and look it over.

+1. I was pleased with mine also.

You cannot make more FI power with a carb hat and a 4150tb vrs say.. a wilson elbow and wilson tb. Wilson rates there 4150tb’s at 1139 CFM. A 90mm is 1170CFM a 95 is 1450CFM and a 105 is 1520 CFM.

My 105mm wilson elbow is just about the same size as the 4150 manifold opening, a 4150tb covers a lot of that opening up.

Just look at what some of the fastest cars out there have. They use an elbow and ford style tb.

I ran it on my 408 firehawk. I used the FAST 4 barrel and a procharger carb hat all mounted to a Vic JR. I lost 25lbs of torque and gained only 4 rwhp over my Fast 90 setup. The Zex perimeter spray plate kit was AWESOME. Hit hard and super cheap comapared to a direct port. If youre building strictly a nitrous car then do it. Otherwise a Fast 90/92 is the way to go FOR SURE

Your CFM numbers don't exactly matter. Like I said before I have an accell 4150 style that flows 1550cfm. If it was only about that everyone would run those kinds of throttle bodies.

There is a difference though and I said it before. They elbows with a traditional style TB are a proven increase in power (in regards to FI) when compared to a carb style throttle body and a hat.

I've herd mixed feelings on this debate for a long time and i must say if your heads and cam match an your intake isn't your not gonna see anything. Thats why my heads/cam match up great and the car needs this intake cuz it falls flat on the dyno after 4000RPM lol It's crazy... I'm scared to see what kind of power it's gonna make with the victor junior and 4150 TB on top.

What is your cam profile? If the cam is not based around the single plane design that can be alot of your problem.

1Hawk

244/248 612/615 on 115LSA. Car made great power on nitrous 850rwhp and made good HP with either of the 2 intakes. Just lost tons of Torque with the Vic JR.

LSWNDR

Well before i go any further what type of heads do you have? Also what does your heads flow at what lift?

Sounds about right... nitrous likes a wide LSA and NA strictly Victor Jr likes a narrow (110) LSA

StreetStalkerZ

IMO that is why his torque fell off with the Victor Jr,no bottom end with the wide LSA. Get that 115 LSA cam out and see the potential of the intake or keep the cam and put the fast back on it.

I run a 108 LSA cam with my Victor Jr/4150 throttle body setup. Plenty of bottom end with that cam it it twisted as far as i wanted to go with the old LS6 intake on the dyno.

Or spray it and get the best of both worlds.

The car is built for the nitous. the 115 lsa cam is strictly in there to take advantage of the nitrous. Ive already gona back with a Fast 92 and 100mm TB. The car make pretty much the same hp on motor and a little less on nitrous but not enough to worry about. Driveability is better and torque is back up.
