Better day today! Quad is getting faster even in shittier air today & the old man got 2nd place. Starting to make some progress with all these changes on both vehicles.

Well, it was a hectic day yesterday with the quad. We finally found out why it wasn't wanting to shift into 5 & 6th gears. A ground wire was loose & was causing intermittent shift kill problem. We also developed a clutch cover leak, luckily I had a new gasket.
Even though the Density Altitude was the shittiest so far today; it will only get worse until Oct, LOL!. We did manage to go quicker with the quad. It liked the gear change, higher shift points & new tires. Today we plan on raising them another 300 rpm. Plus, lowering the shift kill milliseconds from 90 to 60.
Both of us went out in the 1st round yesterday, hopefully we do better today!

Only 5 runs on the new radial slicks. Got 2 days of racing to get them better this weekend.
Hope to go 1 or 2 tenths faster with the quad also.

Only 2 drag banshees last weekend at the biggest weekend of the year on anchor bay.

One of them Banshee's has to be O.G. !!!
Looks like a fun time.

We go to the track next weekend. I don't know what's causing the issue. I can only go by our past experience with the same issue. I have Dexron ATF in it now, but will take the Synchromax along with us.
-
I thought type f has No friction modifiers? thats why its grabs the best. dexron and other trans fluids all have modifiers in differemt amounts to get a certain amount of slip. synchromax surely has modifiers in it to purposely get slip. Just like most motor oils and any sythetic im sure.
I would try dexron/mercon fluids or factory auto fluids like honda or chevy. just a thought to get something to work right and be cheaper then 20 a quart for synchro.
We have always been taught old school with our drag racing. It's known or passed on the use of Type F trans fluid is used for its higher friction to help keep the clutches lock-up. They also use friction modifiers in clutch type limited slips in rear-ends to do the same thing.
This was taken from Mobil 1:
"The frictional characteristics of an automatic transmission fluid are an important factor in the design and operation of the transmission. All Ford transmissions built prior to 1977, and certain models that continued in use during 1977-1980, were designed for a high-friction fluid that allowed the shifting clutches to lock up or engage quickly. Ford specification ESW-M2C33-F covers this type of product, which is commonly referred to as "Type F" fluid."

I don't think it's an oil issue Bryan. The multi-stage arms shouldn't back off much in XX milliseconds and the clutch plates don't need to release to make an upshift anyway. In fact you don't want the clutch to "unclamp" or you'll get that classic slip into those higher gears. A short ignition kill should be all you need to unload the gear pressure just enough for it to easily click up to the next gear. Something else is going on IMO. As you know I'm really busy but give me a quick call tomorrow.
Thanks Buddy, but I think I would be wasting your time!
We had this exact same issue when testing the Type F trans fluid. We made 3 runs at the track & got to 90 millisecond & it wouldn't shift. Did nothing, but change back to our normal oil the same night & the problem went away.
Heck, I don't know if the same thing is going on as above, but we are changing the oil to start. Plus, the boys didn't index the shift lever in Justin's normal spot. It could have been not allowing him to release the pressure on the shift arm.
BTW, we are not running the Multi-Stage in this set-up.

Ever try 5w30 Mobil 1 full synthetic?
While we like the Mobil 1 products we have never used them in the quad. This was the 1st time using the synthetic motor oil. We normally use Royal Purple Synchromax. We switched to Synthetic B&M Trick Shift, but I'm sure we have only ran that for 300' & not using the shift kill.
-
So does the synthetic slip more and solve the shift issue?
We don't know exactly what causes the problem. It shifts fine in the cut gears. I think the motor oil is to thick to allow the clutch plates to release enough during the shift kill. With the Type F it has a friction modifier & caused the same problem. We will find out next time out. Might have to go back to the expensive stuff.
-
We are also trying 10w30 synthetic motor oil for the 1st time.
Keep us posted on the 10w30 experiment.
Well, we switched out the 10w30 synthetic & went back to the synthetic trans fluid. We had to put 90 millisecond shift kill in, our max setting. It still didn't want to shift into the non cut gears 5 & 6. We had the same problem with Type F trans fluid many years ago.
I also did the normal clutch inspection/maintenance & decided on some changes. We had zero heat in the steels. So, I decided to lower the base pressure 24 lbs. We didn't make that change just based off the inspection, but what it was doing at the track also.

N20toofast4u n STY should team up n set the racing world on fire
Come on Tabatha, you already set the world on fire with your BAKO non racing skills.

You run heads up or bracket?
Sorry, somehow I missed or forgot this question.
We run heads-up, index & bracket.

Haven't frequented the drag forums in some time....
Good to see you're still at it. And as always, your bikes always seem to haul ass.
You've always been a help to anyone in need.

What's going on Paul? You thinking about building another quad or doing a car?
We still have some work to do with this new combo!
Don't be a stranger, Bryan

FFS.... Maybe Ohton can chime in and lay out the rules for this. WGAF what it is. Angel is an excellent jockey and can tune damn well also. Not may are going to go sub 4s on anything in the 350ish range regardless of what cyld it is. Fack, Id bet most cant do it with a 421.... Just sayin
^^^^Someone has a clue!^^^^
Angel always seems to hurt some feelings & yes he does better than the vast majority; tuning & racing.
A good many have a hard time going sub 4 with bigger than a 421.

Anyone running a Hayes 7 plate lockup? If so what clutch cover are you running? Thing is pretty tall... I am afraid the arms are gonna hit the cover when it tries to lock up
The only one (running a Hayes) on here that I know was Wheelman Chassis & he hasn't been on since Sept 14. You might try contacting http://www.haysmachineworks.com/

Any updates on the ice racing?

Because I asked about a 350 mtr ? U tlk a lot for not even being there...nothin but keyboard racing fo u
Motor is stock crank/rod & bored .040.

What was your track accomplishments at BAKO?
Tabatha, nothing but crickets to that question.
It's easy for you to point fingers, but in reality you should be pointing them at yourself. Stay away from track racing, you are clueless! I see the reasons why you don't.
You at BAKO, needs to be changed from "TSS" to TS (Top Shit) for your results.

Lol stk cyl n strk mtr...they all three fiddys
You were there, you should have just asked him.
What was your track accomplishments at BAKO?

So that "350" is a stk stroke/rod n 64.xx bore?
Stock stroke, don't know the rod & don't remember the bore. He has so many different builds going on, I can't remember everything. I have a hard time remembering my own shit!

Angel went 3.36 last year on a 300cc bigger triple. The PSDA record for limited 0-1325 is 3.351.
The 707 is a little slow, but had a broken crank. Oh well.
The 421 appears slow, but all that matters is it get the job done! Wins in the 401-475 class & 476-575 class. There's more to a race than the fastest/quickest quad.
350 1st time out & barely got finished for the race. Not much more to say about that.

im assuming track conditions were slow?
Why assume that?
It's not the fastest track, but it's not the slowest either.

Got the OK from the boss lady to get the Billet Cases. If we can get them in time we are hoping to make Gilbert, LA. The pipes are out Shearer's getting the back cone redone.
Lots of work to get done & probably not much time after we get the cases.
Lock Out/Lock-Up Tuning
in Drag Forum

While some of the basics have been covered in this thread. Most refer to air gap as the measurement between lock-up arm & pressure plate as stated by possum.
Some refer to air gap as the distance created between the pressure plate & clutch pack when the clutch lever is pulled in as implied by tricked. The most common reference to this is not air gap, but referred to as clutch pack height.
Now, for tricked's question. Yes, you can adjust the clutch pack height for a quicker reaction. Simply by increasing the clutch stack height. We do this by installing a thicker steel. We have a thickness we use now & getting ready to test a thicker steel/increased stack height. Sorry, I pointed you guys in the right direction, but not giving up all my measurement/information. ***NOTE/CAUTION*** More stack height can cause other problems. Your clutch adjustment window in reference to your arrows on the case/clutch engagement arm becomes narrower & needs adjustment more frequent. More isn't always better!
There are also other things that can be done also. Maybe someone could explain/WAG what can be done with the clutch lever itself...??? I'm in no hurry with this thread & I can take the picture(s) to show, maybe. Would like to here some ideas from the BHQ Member's!
