Twins Turbo Motorsports Supra Vid.
Great action @ Button Willow
Twin's built roadrace Supra: 3.0 ltr. , single turbo , motec , penskes etc. Very highly developed car with tremendous reliability.
This is 10 minutes of it getting serious with a 2100 lb LS7 Lister.
Hope you like it !

Nice going. That Lister sure pulls hard on the straights but you get him through the twisties. Not a track for either car by the looks of it. What's the power to weight of the Supra?

Agreed Patrick -
a very tight course for such powerful racecars. I would think the naturally aspirated Lister would find this track a little better suited than the boosted Supra guy.
Next event is California Speedway (ALMS config.) which should give that Supra a chance to stretch it's legs.
If the Lister could'nt put him away at button willow..... Fontana will be much worse for the LS7.

Seems as if Buttonwillow is becoming synonymous with TimeAttack or Superlap cars. Guess with the proliferation of AWD cars this track isn't such a bad thing for these cars. Be interesting to see what they'd be like up against the 2 cars featured in this video?

My guess Patrick is that a Time Attack car would do well against these cars...for about three laps.
The typical time attack or super lap car is built by a 'tuner shop'. This is a completely different animal than an actual race car constructor.
The Time Attack cars are not actual race cars. They don't have the level of development needed to survive 30-40 minutes flat out.
They would also require a roadrace driver. Hot lapping and roadracing are two very different things....

Boost is always fun 
Are there different configurations you guys run? The BMW club (with more weight and a lot less hp) runs 1:57's.
One suggestion for the driver in the above vid - learn to rev match on down shifts.
There were some supra's that ran in WC but never did well.

95m3racer - there are many different configs for this track. Lot's.
As for 'matching revs' on the downshifts - waste of time. You can get deep into your breaking zone , pull ONE downshift and reingauge the clutch again - all FAR quicker than you can brake/heel toe , downshift , heel toe , downshift again and THEN reingauge the clutch.
The speed in which you can get from Braking Zone (begin applying brakes) to Turn In (back on gas) is far quicker doing it the way this Supra driver does it - vs. the match-rev method. Not even close.
Modern gearbox's don't care one way or the other. Gearboxes from the 'old days'... yeah they cared.
It takes plenty of practice to do it right (just like heel-toe takes to learn) but the benefits are huge in terms of lap times.

You've got a lot to learn on this subject. When you do, you'll know that a single heel/toe rev matched downshift at the end of the brake zone is both faster and easier on the equipment that what your driver is doing. Based on your description above, you are getting quite a few things mixed up. Just sayin', OK?
Rev matching or not shouldn't make any difference in the time you are on the brakes if you know how to do it. And rev matching isn't for the gearbox, it's to keep the rear wheels from shocking when you let up the clutch and keep the platform stable.
Fun vid - fast in the straights, not that fast in the turns, but i'm sure it's a hoot! Reminds me of my old Cobra with 650 hp but didn't like to turn.

Ha ha ha ha ha!!!!!!!!!!!!!!!!!!!
Do alot of effective heel-toe in that '44 huh? Custom pedal assy I assume?
Heel-toe is a WASTE OF TIME - quite literally. It was begun in the early fifties when engine performance exceeded the capabilities of the early TRANSMISSIONS to withstand hard DOWNSHIFTS without shattering.
Later , as transmission "technology"improved , the problem of 'dragging' the rear tires under downshifting became the issue. Heal-toe solved that too.
However , if you were good (like me) you learned to match the car's speed as it brakes coming in - with the next lower gear selection.
Cal Speedway , ROVAL : around the banking and down the back straight , 5th gear redline , everyone starts moving right , lining up for the brake zone so that they can get their foot/pedal dance done AND get the car slowed from 155mph for the second gear left into the infield portion of the course.
While they're doing their thing , I can/do take a lower line and keep my foot planted. While they're braking , heel-toeing ,downshifting , doing it again , maybe doing it again (it is 5th gear to 2nd gear) - I've dove to the entrance and under threshold braking gone from 5th gear to 2nd gear in a single move.
ONE DOWNSHIFT. When the car is slowed to the proper speed for 2nd gear I reingauge the clutch - am instantly back on the throttle.
So... one of you thinks that when "done right" heal-toe is just as fast?
Absurd.
The thought of a 944 driver flailing away trying to heel-toe just makes me laugh. It's about going through the motions that your driver instructor said MUST be mastered - as his driving instructor had taught him.
A 914 with with an original 915 tranny...o.k. It's a box of glass. Heel-toe isn't fast but it will help that transaxle live longer.
30 years of wheel to wheel , two national P car championships , a handfull of regional championships , a GT3 lap record that stood for nearly a decade until 2007.
Being schooled by 44 Spec driver ? Nope.

Yikes +1....this is just a waste of an argument.
Any more pictures of the car itself from the video? And do you have any lap times to compare to, or what configuration you were running to compare times to?
