Your Welcome.

 

I'm looking forward to the WMW pulley myself already having the Detroit Tuned tensioner stop. The money I had set aside for the pulley might be going to new wheels, but that's another thread.

 

Oh, no no no! A pulley will be far more rewarding than wheels, at least any wheels that could be had for something close to the cost of a pulley and installation.

If you're building a show car, get some wheels. If you want to make your car lots more fun to drive, get a pulley (and suspension, and a BSH lower engine mount...) then move on to cosmetic stuff like wheels. If you're looking at SSRs or some other lightweight wheels, that could fall into the fun-to-drive category, but one of those wheels would cost as much as a pulley with installation.

 

I agree with you and performance is my goal too. I just have an opportunity to get wheels that I'm not sure will come along again. As far as the pulley, I have a $125 gift card that I plan on using for a pulley. The installation will cost another $200. I may end up having to use the $125 toward the wheels, but the pulley will be the next performance mod.

 

I agree with you and definitely plan on doing the pulley. Hoping that someone can help me get that done shortly after I buy it. Trying to decide between the 15% and the 17% at WMW. Its a daily driver, so I should probably stick to the 15%.

 

The 15% pulley is by far the most popular for all uses.

Sure, there are some 17s out there and even some 19s (although many stopped offering the 19), but these sizes are generally considered to introduce too much additional risk.

 

Sounds about what I understand as well. I eventually want to go to the GP intercooler and a tune.

 

Not to thread jack, but..................
If you are ready for the tune now, no need to wait. The GP IC will not affect the tune at all. The GP IC is somewhat better on the track, but it does sacrifice recovery times from heat soak and a little pressure loss.

We are having an RMW tune party in Austin in mid Oct, see the other thread. Come on down and get that custom tune, then get the GP IC whenever you are ready and the tune will still be good.

 

Yes, thanks. Still hoping to get my pulley soon. Intake and exhaust do affect tune, right? I hesitated to even ask since I feel like I know the answer.

 

Yes because they can significantly affect the flow, as does the smaller pulley. The few degrees delta in IAT between the S and GP IC will not be significant in terms of tune parameters.

 

So...

but...

So if your boost pressure goes down, but somehow the air flow stays the same (really?) thus not affecting the tune? Trying to understand the reasoning here...:confused5:

If you're going to get a custom tune, get all the parts installed FIRST then get the tune. That would be my advice.

Well, what do i know about GP IC's... I only sold a couple dozen of these and have one on my personal 06. Just my 2 cents.

 

Uh, nice tips?

 

It is definitely good advice to get all engine performance parts installed before a tune. However, the difference between a fully functional standard S IC and that of a GP IC is not enough to make a difference for the tune.

In fact, I may get a GP IC for my car, and I would expect a little better performance on the track coupled with a little worse for the street, but I would not retune just for the GP IC, it is just not worth it.

Of course....... YMMV
