No Title
I understand your concerns, but there are reasons why I want to stay with the SVT 2.5. I have 2 full on 2.5L race motors built up with the best of rotating assemblies and that are good for 9,000 + rpm. I actually even own the 2.5L motor out of the Mirko Contour that ran in WC. The reason I want to run the SVT 2.5l is that it comes with 10:1 compression and that this particular motor has been raced before and didn't grenade. The spinning bearing issue is mostly caused by running the pick up dry in sustained cornering. I will be swapping on the baffled and gated 7 quart pan, plus running a 3 Quart Accusump as well as oil coolers and remote filters. Everything bolts on from the Kinetics built motor that ate the piston. My understanding is that the 3.0l only has 9.0:1 compression and the cams wont run with that low of compression. Too much overlap at lower rpm. If there is a year of a DOHC 3.0L with 10.0:1 compression or higher, I would love to know.
The 2.5 race motor was generating 265 hp at 7250 rpm with stock heads and 11.8:1 compression. If I can turn the stock 2.5L bottom end that high, I will be in the mid 250ish HP range. The other reason I want to use the 2.5L SVT motor, is that I have one and everything bolts together with no issues. At 6,750 rpm, the old motor dropped 14 hp in those 500 rpms and I really need every single one of those ponies. I actually race both the Mumm Bros. Cougar and the Capaldi Cougar and have a race in 3 weekends with the Mumm Bros car and I just don't have time to reassemble the Mirko motor in time. That's why I am asking if the stock bottom end will hold 7,250 rpm and if anyone has already done this? Its the easy button for the weekend and if it wont hold together at 7,250 rpm, I will run it to 6,750 rpm and live with the 245 hp.
I thought you might like to see what I am talking about with the cars.
