Check that your throttle blades are indexed correctly, tweak the air bleeds, or maybe a power valve would be beneficial to keep it clean at part throttle?

BLP has always been my go to for top notch parts and service too.

A carburetor isn't as bad as you make it out to be. After you get it tuned right, all you have to do is preventative maintenance.

I still have (3) 4150s, (1) 4500 carb & all the tuning hardware sitting on the shelf collecting dust. I've won a bunch of races with them all.

Now, last year (late in season) I went to the Wanna-Be FI with a Holley TBI. The reason for the TBI was for the blow-thru cooling. I've been on both sides of the fence. They both have their Pros and Cons; yes, I still have to index my throttle blades to set-up the IAC properly.

I've had a steep learning curve with the FI, I think it will be worth it in the long run! I did notice it's a little more consistent than a carburetor. It only took (4) races to win with it & it consistently wins rounds. This was on a base tune with no dyno time with a new engine platform I've never tuned before.

I'm sure I could go to a carburetor & be quicker/faster, because of 35+ years of tuning them. For now, I'm enjoying learning the TBI.

Over 95% of the bracket field use a less expensive carb for fuel delivery and probably less than 1% use EFI. I attribute that to cost and laptop software interface intimidation. EFI isn’t any faster or slower, and not more consistent or less consistent than a carb. EFI tuning is easy, has many options, and the data acquisition is excellent.

Many won’t use digital ignition and carry a box full of chips. They win as much as the digital racer. Their method offers little in options, even if not used.

I agree with some of what you stated & differ in opinion on other items stated. While my opinion is based, being on both sides of the fence; very limited to the EFI side & 35+ years with a carb. While my perspective is lopsided, it's not one sided.

i think as racers we are all hopeful for a magic gimmick. spend your $$$ and find out there is no such item made by any manufacturer and some times the cheapest most non reinvented item is comparable.

We talk about this all the time around here. What would it be like if technology hadn't taken us where we are in racing? Gimmicks come and go, but reinvented technology by smart folks has been good-overall for the automotive and racing industry. We're a long way from 7" M&H slicks, muncie 4-speeds, welded spider gears and syncro rings, lakewood traction bars, hand ported cylinder heads, plastic driver's seats and more.

Tony and Mike,

Classy responses, thank you.

We all know bracket racing is about consistency in the ET and the driver. If you can do it with a Rochester 2-barrel or a 10-71 blower with fuel injection, good for you.

Gotta nail the dial and DRIVE IT> You both have the knowledge and products to help racers reach the fuel mixture consistency, thank you.

See ya at the stripe one of these days.

Agreed.

Class is obviously in short supply on this forum at times and their responses are appreciated.

Thanks guys! It takes a village...

FYI…



Large bore 4150 1.89 Venturi x 2.125 throttle bores built from the same center section as the twin blade. Went from A to B out of the box with no issues but not worth anything over my ATM 4150 1.70 Venturi x 1.750 throttle bores

Yes, I'm familiar with it. I designed it - before selling my shares in BLP. Tony built several after I left as he remained working there for a while. I wanted to be sure those guys had a new product to offer...

And you're right, the foundation was purposely similar to the twin blade design for machining purposes, however it never made as much power or ran as quick as the twin blade. Good carb though.

Was there any tuning done on the new carb to compare to one that had been run for some time and already tuned for best performance?

Anyone ran a bob book carb?

BOOK carbs are as good as anyones. i have had 1250 Books that embarrassed the new fangled doohickies in aba same day testing

As usual the poor OP has been run off by the pi$$ing match ediot. We'll never know.

He wasn’t run off multiple people reached out to him and so haven’t both of the carb builders he is just waiting to get back to the track

Of course he wasn’t but goober desperately wants that to be the narrative. He’s pathetic too!

Hard to beat…my engine guy was bragging about his brand of choice for awhile….dyno brand x against my BOOK it made 30hp over brand x…

That wasn't to the OP.
