For some reason i do not see how the ITB intake makes much more power than BECKS or Marcella.

hey bud, why don't you try the 102mm thats on sale in this forum and if your not happy with the results just sell it and take a $100 hit on it when you resell it. i think that it would worth the money for a $100 for the piece of mind especially if your thinking of a sheet metal intake ya know. btw, i forgot is this a hyd roller? im still wanting to know how this is turning out for ya. i just bought a procharger kit well most of it and im starting to realize a lot of bs of the little things an how they add up. i think it would be much easier to go with a 440 IMHO

The Harrop 55mm has only been tested to 7000 RPM per a response I received from Harrop. I'm in a similar situation in putting together a top end for 7700 RPM. However, I visited Mr. Beck just two days ago at his shop outside of Houston and have confidence in him. He put together the intake that won the LSX shoot-out last year. Not to mention that he works on all kinds of engines including a SB 2.2 roller-bearing engine I saw. Give him the information on your combination and your goals. He'll make it work. Oh, and you can compare prices too. Another guy mentioned in this thread wants 70% more for basically the same product.

Harrop tells me that I have worked on more of there intakes in the US than anyone....

nice people... nice company...

Call Marcella....

I don't want to fix / tune another one of those POS's

if you want ITB... call kinsler.

The ITB's may not make more power than a sheetmetal but the the driveability is worlds apart.

We have a vette idling at 500 rpm right now with a cam that peaks around 8400rpms.

The car sounds like a mild/heads cam setup and can be used as a daily driver.
We can go around a slow turn in 4th gear at 800 rpms with no surging.

We have done a little r&d for harrop.
Our car peaks over 8000rpms.
We made 609rwhp on a conservative mustang dyno(12% lower than a dynojet) in my vette with a 388ci motor. We still haven't fully dialed in the ITB mani yet.

Having said that there is alot of work to fit it,filter the air,block the hot air, calibrate it, and tune it. All that cost money on top of the price tag.

Still looking around at some choices. And i was wondering is there an advantage between having a Accufab 4500 (2128 CFM) with a sheet metal carb style intake made by BECK or just a 115mm tb sheet metal intake by BECK.

The ITB intake is out of the question, seems like i will only pick up around 30rwhp. And i can not see spending a near 4k.

It's tough to compare without knowing the CFM of the 115mm throttle body.
It would seem there are fewer bends for the air with the top mounted for the Accufab 4500.

Are there any air intake tubing or hood concerns?

I think that the ability to adjust the stacks (runners) length is the key to why this intake seems to make so much more power time after time. Sure the Beck, Marcella etc will make the same power-provided you have chosen the optimum runner length from the start. Basically you can give an intake builder your specs and "hope" what he tells you is right on but it's still a "guess", albeit and educated guess but still a guess non the less.
I've spoken to Beck before about an intake for my car, I asked him about runner lengths etc on different LSX combinations and why he felt that the runner length he uses for ex. an L92 headed motor, was the right length. He told me and I quote "it's what will fit under the hood".
He also told me to give him (intake) specs and he will build whatever I want. Will "I" be able to choose the correct runner length? I think not.

Imagine if you could have 20 or 30 Beck intakes made for your motor, all different runner lengths, and you could pick which one makes the most power on your motor. Wouldn't that be a dream. That's what you get with a Harrop intake. Think of it that way and it's not so expensive.

I plan on going with a 4500/vic jr setup on my motor. This way when I build my turbo motor I will just sell the intake and reuse my TB and everything else.

Marcella makes some really nice pieces. I like the gmpp a lil better than the Jr. however the super Vic is nicer than the gmpp. Carey's Perf. where i'd go if clearances were'nt an issue.

Why would you not want the spider on a turbo setup?

The motor I am building right now is a 416 ls3 with l92 heads so I will be buying a l92 vic jr. When I build my LSX block 434 turbo motor I plan on using some ETP heads on it and will buy a vic jr for those heads.

I saw your build of your motor and all I can say is that it is impressive to run what you did in the quarter with a stock cube ls3 with that Katech cam and a six speed to boot.

Actually, It's a comp cam but spec'd right for the motor. I thought it would run better. Needed some susp adjustments and Just threw a stalled 400 w a brake in it. Hoping to see some new numbers soon. GM racing lifters suck.

Were those ls7 lifters? I haven't heard anybody having any problems with them.

iTrader: (16)

No they were the gm racing lifters, out with them and in with LS7's.

Intake:
The intake that i will be buying is the FAST 102 and have it ported by Vengeance racing when they come out with their porting program in the next few months. I will be losing around 15hp on the top end over a sheetmetal but i will be spraying a direct shot so i can adjust the nitrous for that.

I was quoted $3800.00 to the door last month. I was told they couldn't do anything till after the holidays. I E mail them yesterday to order the intake and it went up.

Beck intake with Direct port bungs for $2200.00. They are taking my heads so they can machine the flanges to fit the heads exact.


What is the biggest DBW throttle body?
