I only talked to him 2 minutes after he broke so I guess a lot could change once he tears into it.

Thank you for all the support. We are trying very hard and hope we can continue to improve.

For the record the elevation on our weather station showed 9500ft above sea level, this is why everyone slowed up. But the track was awesome and the scenery was great Congrats to Ken , Dan , Karl and all the other rotary racers that made the trek.

9500ft? Holy crap.......and I thought dealing with 5280ft was bad!

Dan Schechter

Saturday I had trouble with 2-step, clutch switch, and other issues at the beginning. And sheared the output shaft on launch in qualifying. Luckily the car broke the beams and I qualified #8. I had a used trans in the trailer and swapped it out Saturday evening. Sunday morning, I finally got 2-step to semi-work, and went out for the first elim pass. The talon double bulbed me, so I didn't get enough time to get boost up on launch, and I had a huge vibration at top end. The vibration turned out to be a bent rear wheel, and boost had dropped off 4lbs from Dallas to Denver. Also, my computer shut off on launch, so I could't datalog that run. With no time to get the comuter up and running, I turned up the boost and made some other changes to race Ryan. For round 2, I treed Ryan and got lucky that he had some problems with the turbo, but the bent wheel was shaking my car to pieces, and the trans had some issues. For the final round, I borrowed a set of wheels from a fellow racer, Micheal Bergren, and was confident that the car was ready to run a great run. I got on 2-step on time, and treed the Supra just like the last, but sheared the output shaft on launch again on the other transmission. It sucks because I feel real confident we would have beat him. Oh well...It seems that the stock tranny just isn't holding up anymore, not even for a short time. I guess I can't complain about second place considering where we stood at Sat afternoon.

Sorry for the delay in response, been unloading the cars and working. Plans are in the making for trans...gotta fit in my budget.

Congrats again to D, Rus and everyone else involved with Reactive. And Ken for not breaking any motors anymore! The drives home should be more pleasant from now on...haha...just kidding Ken.

MichaelB145

Yea....at least I figured out that I'm not heating up the slicks enough after I saw what they looked like after you used them! LOL

I now have the line lock fixed so we will see what kind of 60 ft times are possible on my car!


Good to hang out with all you guys with Reactive Racing.....I'm glad fame has not gone to your head!

LUPE

Have you thought about transmission options? Damn, you've got me worried now. I was hoping for 2-3 good passes just to see where I was at before worrying about the trans.

Are you making anymore power now than before? I saw that you put in a new motor, thought you might have turned the boost up more...?

MichaelB145

Yea....got me worried and I'm running a couple hundred hp less than you guys.....I figured while I had to pull the tranny out to replace the 3rd gear syncro.....I might as well explore my options to build it a little more.

LUPE

Dan, been thinking and wondering about something.

Back when you were running bottom tens last year, you were 60 footing 1.3xx's right?

Aren't you still 60 footing 1.3XX's right now?

Well, you're breaking transmissions on the launch correct? Well, what's different about your launch now than before since you're short times are the same?

I don't get it.......

Dan Schechter

Sorry about that. LOL.....They say you want tire temps around 180deg F optimal. I hope the linelock helps you. Let me know how things go with it. You got some good launch shots from last weekend, have you seen them? Thanks again for the tires.

Dan Schechter

Only 10hp at the wheels. I think the other tranny was just getting close to snapping as well, it just so happens that it was in the same weekend. It will probably last a few runs, but one tranny per every few runs is way out of the question! You can probably get 2-3 passes. We did turn up the boost to 38psi. But I'm not leaving the line with any more boost than before, matter of fact in Denver, I left with less boost because of the air up there! I have been looking into options, in fact my cluster is at Liberty right now, to get some pro-shift rings fabricated, but you never know how long that is going to take, it's been there for 3 months. Cryo-treating is the lower budget answer. But new parts are $$! An automatic that can hold up is the long term answer, I've been talking with Russ from Dee's team about some options. Also, there are some in-betweens, but they still involve breaking trannies, just knowing when they are going to go. Any way I go, budget and time plays into it, which is what makes it so hard to fix.

Dan Schechter

I was making around 75 less hp. The difference is torque. I just can't keep up with Mark, Julie, or the Supras on 540whp. I'm not sure if I can catch them even with a strong tranny, however I can be there to take them down when they f*^% up. My 60fts are all over right now because parts are breaking so often, and 2step isn't consistent anymore. Tire pressure plays into it as well as launch Rpm, suspension and boost.

MichaelB145

What sites are you talking about? I think the car looks better launching with the stock suspension like in my avatar when the car was red. Now the front end doesn't lift up as much.

Dan Schechter

No, your front end doesn't come up as much. However, that's a good thing. Modified.com and Urbanracer.com have some good pics. The car looks like its coming out of the hole pretty good.

LUPE

I tested out my 2 step today at 20psi and guess what................. stupid trans exploded!

showoff

u kno not 2 wish bad things on u but i was either anticipating a new thread with you sayin u yanked the wheels up, or a thread sayin the trans exploaded.. sorry 2 hear it had 2 be the trans...

-dj

LUPE

that's okay.......... I'm in the works on gettig a new one right now. Waiting on the person to call me back....

crispeed

What broke? Was this at the track?

LUPE

No, it actually happened on the street........ I warmed the tires up and tried launching it, something let go but not sure what. The only gear I could get it in is 2nd gear and now it won't come out. I was able to slowly drive it home but it sounded like someone poured a box of bolts inside my transmission. It sounded like hell was breaking loose on the way home.

I've got another trans coming to me early next week so, oh well.

I would do the automatic right now but I don't want the down time. I want to get out to the track.

MichaelB145

Something very similar happened to me but it wasn't the tranny....I broke off several teeth on the gears and I was able to limp it home but it sounded just like what you described.

crispeed

[QUOTE=Dan Schechter] Cryo-treating is the lower budget answer.]

Dan
Cyro-treating did not help me. You've reach the mechanical limits.
What clutch/flywheel set up are you running?
There are a couple of options available presently that can help the situation.

MichaelB145

Damn...I thought Cryo-treating would be the answer......What else can you do to stay in SRWD? I have the ACT 6 puck Extreme Unsprung with a stock flywheel. What other options are you talking about?

kabooski

A)I find it very odd that Ken switched ECUs
since MicroTech is one of his sponsers
and the car was tuned by CFT...

b) Easy Street WRX runs a hybrid stock built automatic
MArk with the 240 is looking into a nissan 300Z automatic aswell in the future

why Ari or anyone else in the USA
has YET! to try a perfectly NHRA SRWD legal Mazda "Jatco" tranny
found in either a 3 speed early 79-83 or Turbo II automatics
which are imported here like crazy and mostly thrown away..

http://www.keas.com.au/products.htm

To help with take off with a auto
a Nice shot of N20 does the trick
as evidence by the boostlogic supra that takes off harder then any supra TH400/PG outthere 1.3 60's including Titans cause unlike any other it uses N20 as a launch tool
http://media.putfile.com/boostlogic

Here is a R100 using a Mazda Jatco auto
no n20

best time is now 9.07 1/4
http://media.putfile.com/r100-auto

LUPE

I would love to run a jatco transmission but those are supposed to break with anything over 500 rear wheel torque. (From what I hear)

Also, those older mazda are alot lighter than our FD's.

kabooski

Jatco's also where used on commodore's
about the size of a taurus/sable V8
and people use then in twin turbo applications

I'm only recommending someone try out these auto
that want to compete in NHRA street class
like Ari, Dan, Ernie, Karl etc

If I had the scratch
I would build a 85 GSL-SE
with stock rear end using the Guru
36 spline shafts(strange also makes axles) , Guru oversized LSD
and matching Hubs and there would be no limit on gear ratios.
A Jatco 3 speed auto
13B RE Bridge
GT42-76
100 shot of N20 off the line

100% SRWD legal


low low 9's all day

Dan Schechter

I have heard that if you cryo-treat new parts before the metal gets stressed, it isn't the solution, however it possibly helps extend the life. But it doesn't seem to do any good on used parts since they have already been stressed. Don't quote me on this, it's just an observation.
I am using a stock flywheel, act clutch with a 6 puck hub. I think I am going to try to spin the wheels a little more off the line with 16s (instead of 15s), and a softer suspension to bite less. I would love to get your opinion on options. Thanks for your input.
