911 Exhaust

[Millermancab]

Now has anyone sent their throttle body's in to 911chips.com to be bored out, and if you did was it worth it?

My two cents...
I had an M&K 2/1 on my 87; plusses are 1) it is a good deal lighter than the Fabspeed and 2) less expensive. Ben at M&K is great to work with and the quality of his product is outstanding. I still have an M&K and SSI on my 79SC- changed the cams out too- all of which add to a possible downside in a cab: it is pretty loud. Ok, it howls...which, in certain circumstances, is pretty cool!

Since I had cool and loud covered, on the 87 I swapped the M&K out for a Fabspeed- much better sound than stock. With with factory hx and cams on the car, the M&K sounded "tinny" when you get on the gas, whereas the Fabspeed is deeper and a bit quieter. Just my opinion.

And Steve Wong's chip is super upgrade!

Best-
Matt

Just a guess here: but I don't think boring the TB will buy you much. The stock TB has more than enough ability to flow all the air these engines could ever want. The factory simply did not leave any power here. You'll be better off spending money else where first, like the exhaust

With a cab I would stick with a single out. The two out tend to drone - and that drove me crazy with my old car.

+1! Especially if it is for street use. Added bonus, you get to keep the heater!
The extra HP you gain with headers and Phase 9's can really only been seen at the high end of the RPM band at the track.

This system was installed in a client's garage queen '89 coupe last year and has now been removed to sell the car.
Shoot me an email if interested.
