I have to agree, with a whipple you're looking at 657 hp! and of course superchargers sound great

Thanks, Got Cigs. I'm assuming you traded in that Donzi for a Cigarette?

jtr2kwl you complicate things... I was going to do the 525 but now that you say 657hp, I might re-think. 525 is more reliable, but Whipple supercharger gives me a lot more horse and sound better. And are less expensive. Complicating is a good thing though, sometimes you can find a better answer through rethinking.

I still have it, its posted on craigslist... gonna miss it when it sells though.

If I may interject, my personal opinion to up grade, would be a 525. Its reliable and fast. I wouldnt run out and put an exhaust on your 496 either, the money your gonna spend wont give you much performance wise. I put Gils on mine, ran a little smoother and maybe little better mid range, but not worth the money.
Run it and have fun, do the upgrades next winter.

For the price of a 525, you can have a fully forged, built 496 with a SC making 650hp with great reliability. Acceleration is insane, we've done an install on one before.

I wouldn't necessarily say a 525 is more reliable, but just think, it would certainly be less of a hastle and cheaper to put a whipple on it. Besides, you know that with the 525, you're gonna want to supercharge it anyways, and then you'll be pushing it! will require new drives as well!

496 plus whipple!

----Do yourself a favor before you get rid of your 496, and call Tyler Crockett. He has done a huge amount of development work on unsupercharged 496s and his answers to your questions will get you all amped up. I guarantee it!!!!.......Bill S

+1....mine is there now....granted it is getting the Raylar BCK-106 kit with forged internals. If your wanting a blue engine he has a fresh re bulit 500EFI making 509HP on the dyno for $14K...add a used set of CMI E-tops he has and $16K.....he also showed me is "used parts" room....he must have 6-8 525EFI intakes and enough parts to build you anything you want....just call him.

I just had a raylar 106 kit installed on mine it dynoed just south of 600 hp and 600 tq not bad numbers, I will post water numbers late next week or the following week, just waiting for some tails I agree with third child did the same didn't notice much if anything.... they sure are pretty

A Whipple will definitely get what you're looking for. The 525 may not actually improve low speed acceleration that much over the 496, it just really comes on at higher rpm, also it will require a higher pitch prop. However, I would not do a Whipple without forged internals. Save the cost of the headers.

Ok this is what I'm going to end up doing:
-new forged internals to handle the supercharger
-a Whipple
-if I still have money left, a Raylar kit.
Sounds awesome.
