Installed my accufab to replace the ported TB and I didn't notice any real gains by the seat of the pants... I am too lazy to change it back, though. I'll cut it loose for a good deal if anyone wants to upgrade...

I realize this is for the classifieds and may get moved, but I can't ever find anything on this board's classifieds system.

Is this a single blade or double blade?

How much are you wanting for it? Email me at sportsfan1cd@yahoo.com

 

you say you didnt notice any seat of the pants gains with the swap.
did you notice a gain originally with the ported unit??

 

I thought the throttle response was quite sharper after putting the ported unit on. I did it together with a ported upper plenum, so I can't attest to how much was the TB and how much the plenum...

I changed to the accufab and I would say to not waste your $$$. I was told numerous times to keep the ported unit as going to the accufab might actually cost me some HP. I guess I am a hard learner.

I must have asked 10 guys in the Halo (Houston Area Lightning Owners) group that have one if they thought it helped and the ALL said the same thing: waste of cash...

I think the accufab could provide benefit if the boost levels were way up there....

Cleaning up the stock unit so it flows better/cleaner is probably good enough for the levels of boost everyone is running. Go accufab with a built bottom end or race gas with lots of added boost.

BTW, my ported unit had a little "whistle" to it. It's gone with the accufab or less noticeable. I kind of liked the sound...

How can boost pressure have an impact on the TB, ported or accufab? Correct me if I'm wrong, but the TB is before the plenum and before the SC right?

 

It would have impact in that the blower would be less likely to starve for air running higher boost. MM&FF did an article with a kenne bell running something like 20lbs of boost and netted 17HP with the accufab.

At higher levels of boost, the intake area can be measured for vacuum level. It is possible that with enough boost, the vacuum created by the blower trying to suck more air than is available would create a loss of HP. Adding a great big oval single blade TB would open up that intake and let the blower pull more air.

With the lower levels of boost, I guess there just isn't that much restriction in the stock TB. The biggest restriction seems to be the airbox...

Thanks for the valuable info. Its nice to save some money. Sorry you had to loose. But again, thanks for sharing.

No real big loss to me. I make pretty good money and enjoy the experimentation. The accufab looks cool, but I can't imagine it made any real difference over the reworked unit.

I wish I had the time to do before/after dynos on everything I install, but I just don't have it...

Regardless of choice, I would recommend that everyone that has any boost upgrades to upgrade the intake and either rework the stock TB or go aftermarket to improve airflow. It is something that will enable all of the other mods to give the peak HP they can bring to the table... This should not be the FIRST mod, though.

Ken800,
I think you already quoted me a price, but let me know anyway. Does the price include the TPS or not?
I am planning on buying one of the extrude honed plenums, a smooth intake tube, and doing a stock box mod with K&N panel filter. I figured with your TB, I could bolt everything on as a unit, and keep my all stock parts.

Any thoughts...

No TPS, but changing the TPS from one TB to the other takes NO time at all. I have a meter and can set it to .9xx voltage in less than a minute, so don't waste your money on another tps. If you don't have a meter, come by the house and I'll help you install your stuff.

Ken800,
I got your e-mail on the price. Consider it sold. I appreciate the offer on the install too. ..
