Twin Turbo Ls powered Zephyr - Stuff out of my mustang by tirefryin_s10

9 minute(s) of a 65 minute read

Got the Rear suspension all buttoned up :

Also did some modifying up front lol, Cut the old hacked up front frame rails off and replaced them with some chro-mo tubing/plate. This frees up more room for the turbo drains/piping and cleans things up, saved a bit of weight too:

Still gotta clean up the rest of the engine bay and paint it etc, Engine is almost back together just waiting on new valve springs.

Made some more progress on the OL' POS. Got the powerglide in, built a trans crossmember and also made the column shift work   should be a blast!

Also got the intake back from being painted so got it on. The intake is painted the same cream as the lighter color on the car. Got the intercooler/rad/manifolds etc all on as well

Its coming along slowly.... Re-wrapped my turbo hot sides so those will go on next then its time to fire it up. Still need a driveshaft before I can go racing but its getting close

Well Filled the girl with Water last night and some Joe gibbs break in oil.... Cranked and cranked and cranked no fire..... had me scratching my head for a while. Then I realized it broke one of the small wire eyelets at the back of the passenger head that lead to the ecm and provide ground to the coils and WHAM.

ITS ALIVE!!!!!! Just need to hang the turbos on it,get my new dynatech driveshaft in and a few other small odds and ends and then its time to LET IT EAT!

Went out last night and made one test hit with the new combo:

twin 76s
Powerglide
Afco rear shocks
Column shift
new cam
new brakes etc

Left real soft(1.54 60ft) had the controller set soft and wiht a max boost of 15psi, for some reason I had a brain fart and immediatley out of the hole I shifted to high gear and then the engine just hung in the converter most of the track LOL. Timing was super low and air fuel WAY fat the whole pass as well so there is LOTS of power left even at the lower boost level.

went 9.53@149 in the 1/4 and [email protected] in the 1/8th but then my water pump started leaking so that ended my fun for the night. Putting a new pump on today and will hopefulyl make some more test hits tomorrow if all goes well.

So far it feels like its got some pretty bad *** potential!

Went out today and got some more licks on the car, the alternator crapped the bed but we just charged it up between hits.

Best was 8.72@159 in the 1/4 5.64@128 in the 1/8th on only 18psi with a BRUTAL 1.44 60 foot lol.

This type of coating has no ill effects at all my IATs were still super cold and the coating seems great so far.

Here is a vid of the 8.72 pass just out for a sunday drive lol

So its been a while since an update..... Got the car running put it on the dyno to see how it was fairing with the new combo it made 1010rwhp and 875 rwtq on 18psi on an unloaded dynojet.

Took it to a local heads up street car shootout this weekend and won my class, then turned it up a bit and ran a new personal best - 8.57@162 and [email protected] with a shitty 1.38 60 ft on 20lbs.

So far this thing is a friggin RIOT!!!!

Big thanks to Rob at modular turbo for the hook up on the new turbos.

Turbos spool great but I have spent a LOT of time in the tune making it that way.

I run 3.31 rear gears with a 28" tall tire and the glide
Hooks about the same so far with the glide
.81 a/r T4 housings
Magnum performance 76's not Master Power76s
Talk to robert from Modular turbo about pricing

What rpm it comes on is a loaded question, off the trans brake or just rolling onto it etc just cruising if I hit it it is up into boost by 3400 rpm

8-26-2011

Well went out a couple wednesdays ago ran 8.55@161 with a poor 1.37 60 ft and then went to our local fastest street car shootout on the following sunday and not only won my class and got $500 but got $250 for fastest drag radial pass under 295 and $250 for fastest 60 foot on a 295 or smaller drag radial So I took home $1000 bux and a trophy!


Then tonight it made 1108 rwhp and 936 rwtq on 21psi tonight on an unloaded dynojet through an auto and runs like a dream!

The engine is for sale and can be had with or without turbos and with or without harness and ecm... PM if you or anyone you know has any intrest.

Hey guys I am just putting out a feeler for the car, I am considering selling it complete turn key and building something else. THe car is obviously SUPER well known , doesnt matter what track I am at or what city I am in people seem to know the car.

The car was just featured in a cartech book called "Sleepers, The art of the deceptivley fast automobile"

The car has so far ran the following on 275 drag radials:

Best 60 Foot: 1.340
Best 1/8 Et: 5.50
Best 1/8 MPH: 131
Best 1/4 Et: 8.55
Best 1/4 MPH: 162.5

I am certain with some more tuning and runs on a good track it can run some 8.4x's or faster.


On 21 psi it makes over 1100+ rwhp and 935+ Rwtq, or it can be turned down on 10 psi it makes 790rwhp. Can be driven anywhere just a little loud and no tunes.

I just got the car appraised for north of 54k and I can provide all of that info to anyone seriously intrested, The car has all REAL and all GOOD parts in it no junk, Full cro-mo 10 point cage certified to 8.50 etc etc.

Anyone looking for more info or details please pm me.
