OMG,,,power is unusable on street tires!!!

Friend of mine came by the house last night to help me out on my 87 Fox and brought his 90 coupe that is carb'd n turbocharged. Well, needless to say I was offered a ride.

Just a heads up, this thing dyno'd at 578hp/700tq! Also, this is w/AC, but manual rack.

There's no use smacking it in first gear. Second gear as boost was barely coming on it blew the tires away. Shifted to third, slowly getting in the gas and tires go up in smoke again. 3/4 throttle into fourth gear and she's pulling like a rocket and the tires are clawing for traction. Oh, the blow off valve sound is awesome!!!

I envy you guys w/turbo's and that kind of power!!!! On the previous motor and slicks the car went 10.74's if I remember correctly and that was with all power/suspension twist going to the right rear tire. Wonder what this beast is gonna be like when the suspension issues get taken care of.

no, the ride you got last night was a 10-12psi ride... we haven't turned down the boost yet from our testing.

this weekend we'll turn her down to 5psi and that's where she'll stay until we take her back for final tuning on the dyno.

I saw the build thread (okay saw about 3 dozen times) over on TMs. That is a sweet ride. Motivated me even more to get mine going. What are the rotating specs on that Dart 363? What heads are ya'll running?

I am looking to a Dart 4.125 into a 363 but need to know more. It will be in a 95 cobra, viper 6sp.

lol i had fun doing the build up thread. always makes you wish you had taken more comparison pix on the before side tho.

i have the TFS Track Heat heads on her, but if i had a choice when i was at the stage of purchasing heads, i would have gone with AFRs in a heartbeat. when i needed the flow of aftermarket heads, i was still on the stock bottom end and couldn't have the big AFRs, so i settled for the TFS heads.

her first dyno put her at about 578/702 with traction loss on the rollers and a nasty lean pop right at full throttle. hoping to have some more tuning on the dyno in a few weeks when the new drivetrain is done.

the specs on the block and rotating assembly:

4.125 bore race-prepped DART 4 bolt main 363 cid block
Forged steel 4340 3.4" crankshaft (balanced to a 28oz imbalance)
4340 Forged H beam rods 5.315"
Probe SRS 2618-t6 high alloy lightweight forged pistons

You need to lose that POS Extreme Velocity carb hat and
get one of CSU carbs hat too.
I love mine. My performance shop swears by them. Said the
E.V. carb hats are junk after a while.


Nice set-up. Was watching your build over at FoxBodyForum
cant wait to get my twin 60's on.

only get the lean pop when we first crack the throttle wide open, then it climbs the rpms nicely with a comfortable 12.0

that's weird. i don't remember kevin from CSU describing the EV hat as a POS. in fact, when i bought the carb from CSU, we discussed the hats to look into and he recommended either the CSU or the EV hat. he said they were the only two hats to consider.

other than the divider in the EV hat, they are basically the same design. and from what i have heard from others who have personal experience with the EV hat is that the divider typically only causes problems in cars with more than a 1000 horsepower. and we're not there... yet. lol

plus the divider can be removed with ease should it ever pose a problem.

plus, i liked having an o-ringed hat and i liked the look of it over the CSU hat.

When I installed my 4 brl TB, my peformance shop said
the CSU hat was only way to go, and that they had
had problems with the EV's in the past. Just going off their experiences.


Great build yall did though. Just got my DIS ignition system working
and will have my twin 60's on VERY soon. Cant wait. Expecting similar numbers

Love my DIS set-up, took forever, but looks cool as hell.
Thats my CSU hat on there.
