I do agree though, I can not advertise it as a PROVEN package yet. We have built and delivered the first one, the 2nd one is sitting here waiting on one part and the 3rd unit has been sold.

The two failures we've had since we got it to work have both been my fault and both directly related to the flexplate. First the clearance was wrong, second was a stock unit we ripped the bolts out of.

I am not short cutting this next install. Everything will be right, new flexplate is being made now and I hope we can now make some reliable passes.

We will see.
Agree 100%, i think it will turn out great and i look forward to it changing the game as evolving our cars further.

It does meet the criteria. Let compare real quick.

Cheaper? At this power level you need a tilton clutch (5500) and Dogbox (7000). That is 12,500. That is surely more money than 7500. Cheaper? CHECK

Faster? I guess the term should have been quicker. It is close to the all time fastest the same car has gone and it is at a lower power level. It will go quicker and I would say average times will be quicker. As Dave said it has done better 60ft times and is MUCH more consistent. So faster is a 50/50 at this point.

More Reliable? Well it isnt done being developed but I know one missed shift and a few bad launches can eat up both a dogbox a motor and a tilton carbon clutch. Also launching on a manual can destroy rear diffs and tcases and axles. The auto is much easier on the rest of the car and has been doing great for the time spent actually running the car after the shift controls were worked out. More reliable? Check IMHO.

Now I prefer a manual for a non drag based car at lower power levels but breaking and losing money all the time is not very fun. So once the standard synchro box becomes an issue I would go auto. One bad shift on a synchro box can ruin it. Dogboxes suck to drive on a street car.

at what level? plenty of guys have ran this fast on a bushwacker/quartermaster before. with "some" reliability.

close, but not quite. it has ran quicker and faster with less power and a 5 speed.

again, it "should" but there isnt enough time to say with certainty.

ill say it again. for drag racing auto's generally are better in 99% of all situations. im confident this will end up with the same great results too. but in the end, its still not 100% finished and still may need some tweaking to meet and/or beat a 5 speed. i like dave buschur and want this to dominate, but as said before its not proven and still a work in progress.

i just think its a bit premature to call it "proven" as of this point. anyway, ive crapped on this thread enough and didnt want to. feel free to p.m. me with any further points.

p.s. thank you buschur, im looking forward to the end result!

I agree it isnt 100% proven yet but I beleive it is well on its way and will dominate very soon. Look how the DSM autos have made huge leaps and bounds in the last few years and these are stronger internally.

I have been considering auto for a 1G for a drag machine for a while.

I guess I should say the writing is on the wall and the auto rEvolution is upon us! Hahaha

I don't know that a Bushwacker trans and Quarter Master clutch have gone 9.31 actually, I'd bet money on that hasn't happened. Chris is the quickest guy we have with the Quartermaster and he has destroyed two of them, one in maybe two passes and this last one in less than 6 passes, the last one destroyed his trans too.

My car never went quicker than 9.40's maybe on anything but a Tilton Clutch ($5,000), Powel's car went 9.1 and was on a Tilton, Bowkers car went 9.3's I think it was on a Tilton and our Black Drag car that went 8's was on a Tilton. The quickest guy I know that we've built with our standard Bushwacker trans and an Exedy Triple has to be either Chris at around 9.4's or Jeff who just ran 9.5 at 158 on Nitto DR's this week.

I for one am sold on there being ONE clutch that works for a low 9 second or 8 second EVO and that is the over-priced-short-lasting-impossible-to-rebuild-and-ever-expect-it-to-work-right-again Tilton. I bought THREE $5,000 Tiltons for my car, they are good for about 40'ish passes on a 9.0 EVO. Not for me. I'd rather make 40 passes and rebuild this trans I'm using now, that is actually the goal to be honest. 40 runs close to 8.90's and then if it needs to be freshened up I am fine with that.

For an EVO like that it means you can enter a Quick 16 field, run one qualifier and get in the field and then run 4 passes to get to the finals. That would mean you can run 8 Quick 16 races per year and expect to be consistent and reliable. That's my dream because it's sure the **** not possible with a 5 speed.

I'm kind of confused on this statement. Evos with manual transmissions and the 8 leg Quarter master clutch have gotten into the 8s. Evosick did it

The junkbox usually makes sub 9.3 passes on the race version. Hes is also on a different trans too.

Yea he runs consistent low 9s and has gone 8s. Maybe David was talking about a Bushwacker trans

really?

i didn't know this,i thought there were lots of fast EVO's out there running Exedys and Quartermasters with Shep,Jack and TRE transmissions?

i didn't know you needed a dogbox and a tilton to break 10 seconds?

am i going crazy or something,in fact i rarely see the dogbox/tilton setup here at EVOM,but i though i've seen lots of EVO's running under 10 seconds?

Read what Dave just posted. There are people doing it MAYBE but the synchronizer transmissions can be destroyed from one bunk shift. Consistent and reliable in the 9's is not as easy as people imagine. A lot of people don't share all the destruction and costs of their car builds. Look at EVODan2004's quest for 9's thread.

You're right, you don't need all of that, but you do if you want some form of consistency. If you want to compete in multiple races without rebuilds or breakdowns, at these power levels, there's no better solution IMO. Ask anyone that goes sub 10's how many races they have been to consecutively without issue..

seems like a lot of them to me.

i'm not saying an auto isn't a good thing,it is.i'm just saying that was an odd stement,when you consider how many EVO's on here are running the same power on Shep,Jack and Tre transmissions.i understand you're probably just hyping them up,but,come on man.

there are 1000+whp and 8-sec cars running the 5-speed transmission.
