FS635 "Cold" Weather Pull on the VDR
Me too!! LOL
i dont think i will be going any time soon. Maybe end of January...
In March i will pull the tranny out for a service at Shepherd's and get ready for the season!
We will retune with Junior, maybe even use E85, put my coilovers on, and get 16" Hoosiers! I will definitely run the car on pump on the good suspension and tires... I am pretty sure it can run 10s no problem on pump!
Update!
I managed to take out the car today and make another 3rd gear pull all the way to the rev limiter at 8900rpm.
The pull was made exactly as before with an adjusted IAT fuel trim adjustment as the only change from before. I also subtracted 10 lbs for gas used in order to make it as more realistic as i can...
Also i WOT the car from 2700rpm which is 300rpm sooner than the first pull and i kept it until i hit the rev limiter. Thats something that it shows on the graph and probably thats why the car spooled faster... Next time i will try and start the pulls from the same rpm for a more direct comparison...
The car spiked higher at 30psi but for some reason the boost dropped to around 27.5psi. The afrs were much better, especially up top to the 11.5-11.7 range. I have to say the car felt MUCH stronger than before


The number is pretty impressive i guess!
628 awhp @ 7816 RPM
455 awtq @ 6132 RPM
Some statistics on the new pull:
- At 4836 rpm i had 14.84 psi boost
- At 5063 rpm i had 19.92 psi boost
- Max boost 30.06 psi
- Max rpm 8882.81
- intake temps average during pull 43.67 F
- average afrs up top 11.7
I will work a bit more on my fuel trim so i can have consistent afrs with different weather conditions, but generally speaking i am very happy with the car! Just from the different afrs the car felt to pull much much harder and even the sound was cleaner...

awsome work Im still waiting for dyno time here in germany. I also have a fs635 but im running alittle more boost and have a few more parts then you. I cant keep from blowing my tires off untill 5th and next month i will be running ID2000 injectors and E85. Thanks to freddy and my new turbo. The power delivery is just a tad later then with my old gt35R and doesnt hit as hard but power delivery is way more stable and keeps going all the way to 9500+ RPMs! Hey guy keep us updated

Glad to hear you got the turbo on the car running.. It must be an animal!
Now we just all have to wait for some good weather to hit the tracks..
