I sent my throttle body to Steve last week and I am very impressed with it. It looks just like in the pictures on his website. Anyway I can't tell you how it makes the car run because my car isn't running right now but everything seems to be good with it.

Steve was also a very nice person to deal with. He always answered e-mails in a timley fashion and informed me of everything he could. I would not hesitate to send another throttle body to him.

Anyway if anyone wants a bored out and rebuilt throttle body for a decent price send Steve an e-mail, I was glad I did.

I just ordered an outright purchase for a 2g 60mm TB for my GST Spyder. Steve responded with in a day to my request and this morning I sent the $185 outright purchase over paypal. It should get here in 2 - 3 days. I will comment after all is said and done. If the product is as good as claimed the price is unbeatable. He will even refund $45 for your old TB. If I am happy maybe others should consider it as well.

Just wondering if you received the TB yet...

I just sent my 1g out today I to will give feedback once I receive it as well. But as far as communication goes he is very prompt, every email I sent him was responded to within a couple hours and that was on a sunday.

After machining the bore to 60mm, a new custom fit polished plate is fabricated. I then modify the shaft by cutting away the front half and assemble the TB.
I'd avoid this. You need both sides of the shaft to be intact for strength. The old design Accufab TBs were put together this way and is a large part of the reason they have such a lousy track record with breakage. People complained about it so much and they kept denying it, but finally they got the hint and changed the design to having both sides of the shaft.

The gain in airflow by eliminating half the shaft is far outweighed by the compromise in strength. I'd wager that on high hp cars these will break due to the force of the air on the throttle plate during lifted shifts.

The gain in flow w/the half shaft mod is about 5% or equal to the dfference between a 63mm TB and a 65.5mm TB. I've been doing Buick GN TBs with the half shaft mod for 10 years and there's several hundred of them out there running between 15 & 28 lbs of boost with no BOV and there hasn't been a shaft failure yet.

Several of the 70 or 80 DSMs I've done were plus 500 HP machines and no failures to date. I can do it either way but not to do it is really leaving something on the table when there is little risk of failure. I'd venture to guess that the Accufab fiasco was due to their shafts being made too hard.

Just to repeat: The Accufab throttle shaft is the ONLY shaft failure I've heard of including all the makes I do and the ones other people have done.
Thanks

This sounds like a valid argument. Some people on the AEM board have complained of this with TBs other than Accufab:

Thanks for taking the time to come support your case. If the stock DSM shaft is really better at handling the pressure even with half of it removed, due to its flexibility, then that's a new one to me. If people would just NLTS then this wouldn't be a problem anyway. ;)

The accufab TB shaft failure was inpart to people have the TB setup completely wrong. In addition to this, the machining on the throttle shaft was poor at best, with plenty of material taken out in a way that promoted stress risers.

If you have any details about how you do the machining on your TB shafts, LMK. PM would be fine as well.

I'm interested, I just want to make sure what I'm getting into.

I just happen to have a spare 1G T/B sitting here. I will give Steve a try in a couple months. :)
