552rwhp!!!

A/F ratio looked good the entire run. The first run there was 3 degrees of knock retard at 4600 rpm. The second run was clean.

Does the Metco 8.6 pulley require you replace the front damper or is it a direct bolt on? This all was done with no tune? If so that rocks!!!

wow great results. I actually have a question for Ted. I just read the convertible is slower than the coupe. Will the above mods make a noticeable difference in the convertible compared to a stock coupe? I just sold the coupe and felt that could have needed quite a bit of help too, so I am disappointed to see that the new convertible I just ordered is slower... It would stink to do all those mods just to get the convertible back to the stock power of the coupe...

Its only slower due to weight of the vert top. Im sure its not even noticeable, if you bought the no tune kit from JRE which provides about 75rwhp without a tune, you would definelty be faster than a stock coupe.

The only Reason a Convertible would be slower is due to it's added Weight.

It is like when after a long night of drinking the car feels much slower in the morning because there are 2 fat chicks in the back seat asleep.

Seriously, My 75 RWHP No Tune Package is Amazing, My car is rediculous, I can spin the tires at almost any speed.

LMFAO! Unfortunately I can relate to your drinking story, but usually for me one overweight one was enough... ahhh the blurry thoughts I have from the Heavy Metal 80's...

I'm a few states away and will be seeing you in the spring. I can't do any of this by myself... I am hoping by then there will be a few more no tune mods out too...

You have to purchase the hub also, total price was about $800.
Yep, no tune!

Which pulley is the "10%" pulley, the 8.6" or the 9.1"? I can't seem to figure that out as neither seems to calculate out to a 10% ratio increase or diameter increase.

The ATI pulley is 8.86" which is 10%. I bought mine from JRE. The 9.1" is 14% OD.

I see an 8.6, 9.1, 9.55 and a 10. I do not see an 8.86. This thread mentions a 5% and a 10%. Which is which?
