Throttle body

[3xBlackCobra]

Doesn't seem to be much info here when doing a search, but the reviews for the accufab sbtb w/ plenum on different websites have people claiming anywhere from 25 to 50+ hp gains, depending on your mods.

Does anyone have real before/ after numbers? Over 50hp gains seems like a stretch, even with pulley/ tune mods.

Trying to determine whether the price is justified, since they list for well over $500 new

The hp/tq gains are minimal at best. The big gain is in throttle response.

Thanks for that. Interesting thread, especially regarding the dragon setup.

Kinda debating doing this or saving a little extra for a bigger brake kit.

No problem. It’s a very good read. I know it’s mainly ported stuff but interesting to see actual real life difference with everything being the same. Same car, blower, dyno etc.
I honestly wouldn’t upgrade it. I’d upgrade it when you went to a bigger blower. The power gains are going to be minimal on a Eaton. I remember driving my friends car with a 2.3 whipple and a Accufab throttle body and my car was on a stock tb. His throttle was stupid sensitive compared to stock. I had the RPMs up to like 3500 and wasn’t moving!

Yeah I'm thinking the people on the reviews i read "estimated" their gains based off of the better throttle response.

Think I'll save the $500+ for the brakes

I have no idea about HP/TQ gains as I'm not a big dyno guy.

I bought my Accufab SBTB and plenum for aesthetics reasons. I took my supercharger off and got it powder coated and did a lot of dress up to include new Metco pulleys and powder coating other parts. Once I put everything back together and drove my car for the first time after installing the SBTB my throttle response was super quick and crisp. It almost felt like a different car. As I said I cannot tell you what, if any, HP gains it gave me. But it is a blast to drive and responds faster than my original TB.

I don't know if the $500 price tag is worth it, but since I got what I wanted (a better looking setup) and a quicker throttle response to boot, I'm definitely not complaining.

@Black Gold 380R I really do like the look of them, and the improved throttle response sounds fun... just hard to justify the price without significant performance gains.

Can you post a pic of yours, including the powder coated sc?

I hear you. It is a lot of coin, but as others have mentioned if you plan on upgrading your supercharger later it will be worth it at that point.

Definitely the best looking plenum from what I've seen

Ported and polished Accufab TB/Plenum and ported and polished Eaton.

 

[NateDogg]

I'll be selling an accufab TB soon. I dont have the plenum though.

 

[c6zhombre]

Here's my billetflow SBTB, I have no idea what it adds as far as hp/tq, but I would think some at 22lbs

But I like it for the looks primarily

You need a polished whipple.

yes, factory oem rails wrapped with a product made by Thermo-Tech.

 

[Black Gold 380R]

You need a polished whipple.

That would be the only way I would go Mike. I have to have a polished supercharger if I upgrade. No flat black for this guy LOL.

 

[KLLR SNK]

Mike you would be surprised at the people that think it is a polished Whipple.

Mike you would be surprised at the people that think it is a polished Whipple.

I thought it was at first but in my defense i havent seen an eaton in years.
