How much E.T. will I gain with this ?? I posted this earlier over in the drivetrain section for some odd reason, must of had a brain fart...
I am going to be converting to a TH-400 with a PI4400 stall, a Moser 9" out back with rims/etstreets for tires....I still have my "stock" firehawk BILSTEIN suspension, bilstein shocks with eibach springs....I will be keeping the current firehawk rims in front because I can't afford skinnies right now...
The car is still a 6-speed, but I've sold all the parts, on the dyno it made 360rwhp and 350rwtq, with this new setup what kind of et's should I see off of a trans brake or a regular hard launch??
Thanks,
Brian

Re: How much E.T. will I gain with this ?? Too hard to say. Not enough info. You didn't even tell us what your times are now. Raceweight? Traction situation before and after? Gearing before and after? Is that an actual 4400 RPM stall (I assume it is since I've never heard of PI calling a converter a 4400?) More? Less? STR of this converter? Internally stock engine? What 1st gear in this TH400???
Give us the full rundown and we'll make a guess. <img src="gr_stretch.gif" border="0">

Re: How much E.T. will I gain with this ?? The Th-400 will have stock 1st gear ratios...
My raceweight will be around 3650 or less...
I never got a "real" time on the car now...I had a 2.4 60ft with the 6-speed trapping at a measily 111...the et was 13.2, that was with a 4.10 gear on street tires... <img src="images/icons/rolleyes.gif" border="0">
In the rear with the moser I will be running a 3.73...with some 26"x10.5x15" ET streets connected <img src="gr_stretch.gif" border="0">
The converter decesion is still up in the air...I would actually like some help on that subject, I'm new to the A3 "converter" world, I want to stay 4400-4600 stall not higher or lower, but it will be in that range...
The car made 360rwhp and 350rwtq with the 6-speed tranny <img src="gr_stretch.gif" border="0"> Its stock heads/cam/headers/all the other goodies...
Hope that gives you a little more info...
Thanks <img src="gr_stretch.gif" border="0">

Re: How much E.T. will I gain with this ?? I just can't stand not being able to go to the track...well the parts aren't in yet, but when they are... <img src="gr_eek2.gif" border="0">
Re: How much E.T. will I gain with this ?? I'd say high 11's. Might be better than that with the transbrake. Might 60 ft really well.
3650 raceweight is pretty high. Most of the fast bolt-on cars are at like 3200 raceweight.
I went 11.76@114.5mph with heads, cam, 4400 stall, 3.50 gear, 16" ET Streets and weight reduction. I had skinnies and other weight out. I figure my raceweight was 3500.
You won't have heads, but you have a transbrake, but you will be heavier...
BradWS6's best when he had stock cubes was like 11.5 thru cats at 3650 raceweight.

Re: How much E.T. will I gain with this ?? I might be too pessimistic on the ET.
Heck, you might ET great with a transbrake and be in the 11.6's for all I know.
Good choice on the gearing, for laughs I have left my gear selecter in 3rd and gotten on the highway, let's just say that with 4.10's and 3rd it was ridiculous.

Re: How much E.T. will I gain with this ?? Im also going to dyno it again to see how sloppy it is and to see how much power the trans and converter take away... <img src="gr_stretch.gif" border="0"> just for an experiment

Re: How much E.T. will I gain with this ?? should be in the 11s now with a decent 60ft (1.59 or better) with 360 hp. That is a fair amount of HP but 3650 raceweight its heavy <img src="graemlins/gr_cry.gif" border="0" alt="[whiner]" /> . I would have made it much lighter before messing with a TH400 personally. (but I have read your situation with the 6 speed and all so I understand) I think mine is heavy and its right around 3300 even raceweight. would like to see 31xx some day with out just the one seat only look and no console, etc.
very curious to see what it dynos at with the TH400 compared to the 6 speed
I would have gone 4.10s too if I were you unless you make LONG highway trips...you can always add a gear vendors OD later down the road if you want to make it a gas mileage machine
