The $230 unit is made of Cast aluminum. It is compatable with cruise control and includes a new Throttle position sensor for the $230 price. It is 58mm

The $300 unit is made of annodized aluminum (colored), it is billet aluminum, so it looks better and is "smoother". It is adjustable from 58mm to 61 mm. It does NOT come with a TPS sensor, but is compatable with cruise control.

The $230 unit is "stealth" and no one will ever know it is not the stock unit. The $300 unit is "flash" for show cars and ultimate high performance.

So if I want high performance and better gains out of the TB I should get the $300 unit? Is it really important to have the TPS sensor?

The Two TB's available on www.sharkracing.com

The "performance" one is lighter, and has a larger opening.(61mm vs 58mm)

99.99999% of you will NEVER see a dyno difference/gain with the 61mm unit, but it is there as an option.

Yes, it is important to have the TPS sensor...as your car will run like poo without it. Of course you can always reuse your old one...but giving you one is worth $45 bucks if you ever needed to replace it from www.stcharlesauto.com

One more stupid question
With the $300 unit will you sell a TPS sensor
or do we just use the one we got?
And thanks for answering my questions. wink.gif

Random, don't you have your intake ported or bore out or polished to have the full performance gained with using a larger throttle body ?

The $300 unit does NOT come with a TPS.

The IM/TB interface should be bored out on the IM side to match the diameter of the TB you are purchasing to see a benefit...yes.

The polishing is just a service OnPol does at the same time. Some people have enlarged their own IM's using a dremel, but I have yet to see any photos of said work.

What power would the cheaper one give? Much, at all?
