408 + Stage X = ???



220's @ .050 with under .600 lift on a 114 lobe. It's a new lobe design we have been using on turbo engines with a very aggressive ramp profile. Spools the turbos wicked fast and makes huge torque and very flat HP curve. Usually see power peak by 5000 rpm and holds the power all the way to 6250 or more depending on boost.
Used the same type of cam on a turbo 4.3V6 and made 610HP and 750 Ft.lbs all under 5000 rpm.

Should work wicked!! Hold on when those turbo's come on!!
It's fun!
@ 9 psi 617 RWhp / 648 Tq
@ 13 psi 742 RWhp / 720 Tq
A partial final pull was done @ 16 psi , but the rear tires were lighting up in smoke and would just not stay on the dyno . From what Mark @ Campbell Automotive has said , the pull broke the front strap and fuel issues came up . It seems the upgraded ECS fuel system isn't all that it's cracked up to be at this higher level . After trying a few times @ the 16 psi level the best number they could record before the tires broke to hell was 829 RWhp / 839 Tq .
I had a chance to drive it around the block some , even with the fuel problems this thing is absolutely insane. The boys figure there is around 100 hp left to get . We were shooting for 18 psi , but their equipment just can't handle the power .
The next step is to modify the ECS system ( they have figured out the problem ) and bring the car over to a friend of Marks who has a better Dynojet and try out the fuel revisions and attempt to get a better tune .
My hat is off to the boys @ Campbell for the job they have done to this vehicle. A few of the items they have done to this car IE . oil cooler , invisible catch can and hiding of system components are one-off and fabbed up on the fly in their shop. The work they have done is second to none in my humble opinion.
Once the final bugs are worked out and testing done , I will repost results , but figured I would post what we had now as a nice little sample.

PS Anyone who thinks the t3/t4 turbos are not big enough to make any "real" power , I have to say you guys are completely off your rocker .
Well..................Fuel system problem solved and:
692HP @ 9psi on 91 octane pump gas (0 knock 11:1 AFR)
770HP @ 13psi on 91 octane and methanol
840HP???? @ 16psi on 91 and methanol with the tires smoking (still no traction)
We believe the car could make 900+rwhp no problem if we could make it hook and run it to 18 psi but the tires will no hold on the dyno and the torque from the engine comes on so hard at 3500-4000 rpm it blows the tires of no matter what we do to strap in down. We even had 350 lbs of people in the trunk.........but no help. We are going to put the car on a Dynojet next week to see if we can hook it up in 5th or 6th gear..........our Mustang dyno only goes to 160mph and were there at the middle of 5th gear.
The car with the straps of tight as possible, walks right out of the rollers and smokes the tires as soon as you get in the throttle at 14-15 psi.
Will post some video soon.

Also, any dyno graphs yet?Nice work!
Not getting into the fuel system thing. I will be talking to doug@ECS about what we did and if he chooses to say that's fine, but last time the subject came up........................well you probably have read it.
Will post some more info soon like graphs and stuff.

To you guys for working on the fuel system issue.I was just about to order the ECS fuel system, is this modification you did something you could repeat, maybe send you the ECS system you do your magic then send me the kit???
Do you have a special cam for a smaller ci motor??

SO WHAT WOULD THOSE #'s be if ran on dynojet? imagine on a dyno pak

I have heard about things like this happening
Good luck on the dyno jet. My car was spinning at 760wrhp that was with extra straps and about 400lbs in the trunk. oh what fun
Great numbers

735HP / 790Ft.lbs on straight 91 octane pump gas.
NICE DRIVING DAN!!
The car is all done..............and stupid fast.

Good work...
Good work...
too small ? is this the stage X kit from TTi ? and they are too small for a 408 cui?
I plan to go this way with TTi kit for a few projects here in Euope,
hoping to see 1000 rwhp on 98 octane (94.2 us spec)
So what spec do the stage X have ?
TIA
