I am a Mustang guy, and used to running high 11's low 12's. I just test drove a 2005 EVO 8, and "damn" I am impressed.

I read thru some threads, and looks like EVO's have a good aftermarket. How much horsepower can the EVO blocks handle? I see changing the exhaust, adding a downpipe, chip mods, etc gets you more horsepower...but what about a 150 shot of NOS, or a really big turbo? How much max horsepower can you get out of these? 500hp, 600hp, ?

I know on stock Mustangs 4.6 motors...you can safely get 450 HP on the block before you have to start worrying about your drive home....

The most I have heard of on a stock block is 550 HP at the wheels (that would be 655 flywheel HP). I figure that was a "glory" run on the dyno.... but not many people are pushing the limits of the stock block, so no one has acutally found the limits of a totally stock block. I will be "self limiting" to 450 wheel HP (535 flywheel HP) to keep from grenading my block. That should be good for mid 11's on pump gas with alcohol injection, high 11's on pure pump gas.

Good luck,

Keith

There are 600+ whp daily driven Evos with the GT35R. You can get 350whp on 93oct out of the stock engine/turbo with just cams as the biggest mod. 400whp on the stock engine/turbo w/alky injection. 450whp on the stock engine/turbo w/alky and C16. After that, it's all done with upgraded turbos...some are up to 800whp, but I am sure the engine is fully built...same for those with 600whp, I believe.

My '05 has $900 in mods (cat-back, boost controller, s-afc, K&N, metal bov) and ran [email protected] on 99oct. My best mph was right at 111mph, but 4th gear on the 6spd runs out right at 111, otherwise I think I had another .5-1 mph to go, since I was bouncing off the rev limiter several counts before the traps. This puts me at an estimated 320whp with easy bolt-ons installed in my driveway.

Thanks for the replies. Now all I have to do is fine an EVO at a decent price. The $35,000 price tag on the 2005's is a little steep...no discounts really from MSRP.

They shouldn't be 35k. Only the MR ever cost that much, and even those are going for 33k now (invoice). You can get an 05 GSR for 29-30k now that the IX is coming out. Maybe you just need to shop around outside your area...

I picked up a used 2004 in Philadelphia with only 3,200 miles and bone stock. So now I can get started with the upgrades. Sounds like exhaust is the first thing to get the most bang for the buck...

Get a boost gauge first, then go with turbo-back exhaust (TBE w/test pipe if you can get away with it), manual boost controller (MBC), K&N drop-in filter, and either a flash or S-AFC for tuning.
