New project
 

REW street port, S480 turbo, GF101a trans, 8.8 rear end with 31 spline axles and 4.56 gears. 27x10 tires.
JW lower intake with a 90mm throttle body. 31x12x4 air intercooler. Six 2200 and two 1000 injectors. Magnafuel 4303 pump with 10an feed line. 2.5 gallon fuel cell. Pump E85 fuel with water injection.
No bumpers, power windows or sunroof. Lexan except for the windshield.

Old car was 2750lbs. Hoping this one will be in the low 2400lbs

4th or 5th heat cycle, idle at 900rpms. roughly 4oz per gallon of premix

Looks good and clean!

When are you planning on making a test run/pass?

What 2200 injectors are you using? Man that 8 second pass should be in the bag for you just by dropping the weight.

Thanks! Let hope this last two months of work is worth the effort to get this thing in the high 8s. We should know early next month.

Good luck! Should be fun! Let us know how it goes!

2393 lbs with driver. Down from 2750lbs. Still running a 55lbs battery and stock windshield. Thinking these items can lower the lbs another 50lbs.


happy camper!

Made it off the mustang dyno today with the motor still alive. No numbers. Just looking to make sure everything is working.
To freaking tired to test tonight so hopefully Friday night. I can't wait!!!

looks great and she is light now ! it's going to run 8's for sure

btw. I run the same Tranny but clutchless in the 1-2 and 2-3 clutch assited 3-4

:icon_tup:

Gf101a is a nice trans for the money!

made it to the track last night. Nothing big. Just to see how the car drove. 21 psi shifting at 7500 rpms. No launch. 148 60ft.
11.0 at 119mph.
it drove straight and smooth. Happy!!!!

ran to much water for that power and it slowed the car down . Three m15 nozzles. Use to run two

1.48 60ft and you werent launching the car, NICE!

Where you do you normally shift at, 10k rpms?

Usually try to shift around 9300 + -

The launch was at 8200 with very little boost. Dumping the clutch. My flow control jet is now a .019. It allows the car to leave easy. The rpms did fall a bit to much because of the lack of power but usually on a power launch the rpms stay in the high 7000 low 8000 range where it use to drop to 6500rpms. It almost feels like a torque converter off the line with the small jet. Motor is happier.

60ft 1.38 1/8 was 6.0 at 113 1/4 9.5 at 138
Just over 30psi. tune was at 75% good. Still to much water/meth injection.
Tune is judged by my shifting rpm. I shift by how the motor feels and pulls. Last night shifted between 7800 and 8400. That's telling me the tune is to fat. Thinking the base fuel tune is close and need to cut back on the meth/water 50/50 injection from three m15 post turbo. total 45. to around 35 total. Keep the m5 pre turbo.

:lol:

AWESOME pic!

:bigthumb: nice rear end pic.

Got the car to run a 9.5 on the old tires. Bought some new ones and tried to put some power down last night. No luck. Had to turn the power down to get it to run a 9.5 with out spinning the tires in 3rd gear. ( bad launch, 1.41 )
M&H 27x10x15 same as the old ones. Aired to 11psi. small burn out, Maybe the new tires need a bigger burn out.
This weight reduction is very noticeable. Breaking is easier and car feels like its on rails. Might have to put the rear wing back on.????? :scratch:

Big burn out

1.32
5.73 120
9.004 150

Just ran that elusive 8.9

and got booted off the track.

Hard long path!!!
amazing what a street port and pump e85 will do. Still on stock turboII leading ignitors and trailing coils. BUT with the new car found some voltage increaser boxes. 40$ each on the leading coils only. Now the coils are pushing 18 volts :nod: thx HC.

Congrats!!! Times are going to keep dropping good luck, have fun and be safe.

Car made two passes Saturday night. 8.96 and 9.004
Also was not pushed on the trailer afterwards. lol

Fantastic news! We admire your hard work and dedication! Excellent work dude! The motor doesn't sound like you are leaning on it very hard either.
