Wow, I must have imagined all these cars running for years just fine on a stock longblock. Thanks for setting me straight! lol.

Yes I have. Just a few months ago I finished the rebuild on a sub 800 rwhp single turbo termy. The heads were in perfect shape save for the two cylinders that got beat up from the fuel pumps taking a shot and leaning out in the middle of a pull. When we pulled the engine apart, all the factory bearings looked brand new with not a single sign of wear. The other 6 cylinders were in perfect shape and had been holding over 800 rwhp for a couple years. Customer is now upping the boost and adding e85 with the intentions of making as close to 1000 rwhp as he can with the turbo being his limiting factor. Ask anyone at the shop or anyone that regularly stops by what condition this engine was in when torn down. This is just my most recent example.
Originally posted by majorownage View PostHave you ever seen a stock cylinder head after this type of power? Everything is toast. The stock valve guides (powdered metal) cannot keep up with massive amount of heat with associated with 1000rwhp. The seats also will show a considerable amount of wear. Not to mention the rings will be roasted, the stock aluminum backed bearings will be pounded to death, and possible piston scuffing.
There is a reason the ford gt/gt500 heads have bronze guides/copper-be seats.
Just because the car will survive a 1000rwhp dyno tune session does not mean it will last the test of time.
If the car was only used occasionally, and not abused (keeping WOT sessions less than 10ish seconds), the stock engine factors of saftey should be able to keep it operational...at least for a while.
There is a reason high specific hp engines have shortened engine life spans.

I hear there is a coyote running around with a KB and 13psi of boost in the 700rwhp range, through the auto. Take a bite of that one Steve if you think your swap car is that nasty.
To the guy that thinks the termi motor wont take 1000k rwhp in stock trim your a fool. With a good tune I have personally seen it take place and rape a lot of people in the Dallas area. Matter fact it was pulled out after 20k miles, and replaced with a stroker. Put it into another 03 cobra made close to 500rwhp with a ported blower and still runs to this day.
I love the people that spout out a bunch of nonsense, get a real tuner and you might be surprised.

Simply not true. 2012 automatic with 3.15 gears here, ran a baseline 100% stock @368hp. At 15% loss, that would be 430+ at motor.

The coyote block will handle just as much, if not more power than the Termi.
The coyote heads are way better than the termy heads.
Not saying the Termis aren't bad ass, because they are!
Just saying there is more potential with the coyote.
Took a blower to make 390hp in the Termi. Coyote makes 412hp NA, With a blower and relatively low boost, over 600hp.
How much boost does it take for a Termi to make 600?
My OPINION is the Coyote is a better motor than the Termi...

Z363 tested
Got the 363 running and out for testing this past weekend. Went and had it dynoed to check air fuel so it was safe. Engine ran real strong. No issues with delivery or install either. Added the Victor 5.0, Stainless Works Long Tubes, and Distributor and it fired right up.
When I put it on the dyno, we spun it up to 6,000 rpm, with 93 octane fuel, and 12.5 Air Fuel Ratio.....it pulled 420 rwhp and 399 rwtq.
I plan on getting my power pipe back on with modification and spinning it to 6,500 next tune to get over the 400 mark on torque.
All in all, very happy for the money."Racing is life.....everything else is just waiting" - Steve McQueen

Just have to find someone to buy my motor first. Would like a 408 with cleveland mains, solid roller and maybe Fuel injection. Thing is, I really only need 30hp for ST2 but to get that power is going to cost as much as going up 150hp....see my dilemma?!"Racing is life.....everything else is just waiting" - Steve McQueen

Just put new Eradispeed rotors and PF 01 pads on.....stops on a dime with the ABS and 2900 lbs!"Racing is life.....everything else is just waiting" - Steve McQueen
