Good luck Mark!

 

Didnt make the cut. I got in a .019 reaction and a .009 was the cut off. The timing system is a tad different there then Milan where ive been at all year. The roll out is a little longer and i sware i was going to go red and went .019. But anyways tried the 2 step for a shot and it fell on its face. I could build 3 psi at 2500rpm with the cut out/in 40 rpms apart. Being I only got 2 time trials the 2nd i just went normal.

Ran 12.52 with the 2 step....1.86 60ft. 3700 DA terrible hot humid air.
Ran 12.67 normal launching at 1800 rpm. 1.98 60ft same terrible DA.. even worse really.

One more points race then im going to work on the 2 step more and see why i just cant build much boost with the 2 step. It starts banging here and there but then the KR kicks in and i get scared that it may hurt the engine so I stop messing with it. But soon I will turn up the boost a tad and work the 2 step more every weekend that i can hit the track.

I did win 2 rounds sunday at the event and lost in the 3rd round. Guy had a .021 rt to my .066 rt so at the end i lost and he made me brake out as i was chasing him and just caught him at the end but my 112mph vs his 85mph is hard to judge when its within a few hundreth of a second.

Had alot of people check out the car. Was nice to see that.

My burn out pic from the weekend and just some randoms...






My 2 rides for the weekend the camaro and the outlaw 525


Im pitted over there somewhere..... it was a packed house this weekend.

 

Just washed it up and am excited to hit the track sunday in the 92* forecast heat! LOL. 2nd to last points race. I missed the boat to Indy this year for divisional. Clearly I had a nice string of tough races along with Milan raining out 3 points races so far and me missing one. Oh well, its all fun.

 

the 2 step is going to trigger the knock sensor no matter what u do, best bet is to wire up a relay that cuts of the signal from the knock sensor while u have the 2 step active.

if it was tripping the sensor when u launched it propably cause it to fall on its face

u went .15 faster even though it fell on its face ? what was the mph difference?
get it not to bog and u will have a huge difference in et/mph

 

Adjust the knock recovery rate so that the ECM blends the timing back in faster, after a knock event. For anti-lag, isn't it better to have the timing backed off anyway?

 

u want the timing back to normal soon as u come off the antilag to stop the bog

 

The mph was actually slower 109 mph vs 111mph. But I figured the mph would drop lower with better 60fts

I could also change the kr so that it is ignored under 2800rpm?? Just a thought. I had it dialed it to cut at 2400 and resume at 2370 the last time I used it.

 

mph will pick up when it stops bogging
set it up to ignore kr below 3k for the track/antilag tune

 

Well i tuned a few chips today and got a solid one for about 14.5psi. It was 13.00-13.5psi before. I like the timing and the 11.2-11.4afrs. The intake temps go up but still never more then 15 degrees above ambient on a long WOT pull. Honestly I can't tell if it's faster...it all feels the same anymore.

Hopefully I can start etching at that 11.99 mark in the next few weeks. Going to work hard at the 2 step next weekend for a test and tune weekend. So crappy 60 fts this week im sure but baby steps. Its still a points race tommorow and i plan to win alot of rounds.

BTW the injectors are slowly running out of steam. 75-80%ish on the latest tune. Current are 48Lbs ones. I may need to get a bigger set one day or get a different regulator. The one i have works good though for now. Adds the psi to the psi of boost thankfully.

 

if u have he bog and cant burn a new tune at the track add air presure to the slicks.
the idea is to add presure until u get 1-2 rotations on the tire ( spinning) out of the hole and this should stop the bog

the spin keeps wheel speed up and helps with the bog issue, a dead on hook just about always induces a lil bog until the tune is spot on ,ive always found my car to runs its best with just a touch of wheel spin off the line

 

Well as I was driving to the track yesterday the boss called and I had to go into work. He's on vacation so im filling his spot. Im a apprentice so getting sunday double time pay isn't too bad. Helps buy more car parts. So im going to try and race next sunday.

 

12.25 at 114mph first tt. Will add pics and stuff later.

 

antilag or footbrake?

 

Foot brake. 2100 rpm launch. That was the last points race of the year so from now on Im focusing on the 2 step. I firmly believe that with the 14psi tune im running now with some cool air and a good 2 step launch it'll run 11s with ease. Heres the slip.

Was 78 degrees out 69* dew point. Very sticky and humid.

I didn't get a vid of it as I really didn't exspect that on such a humid hazy day but I did get a 12.41@113mph which ill up load in a bit. That was when it was 87* and the air was just horrid.

 

Impressive stuff man! If performance swings as hard as mine does with "climate change" than you will go 11's around October. Sweet quad!

 

2100 launch? No wonder it doesnt get out of the hole very quick lol. 11's with a good launch, thats an mid-to-upper 11 second mph

 

Yea light launches.. 2200 actually on the data log for that pass. I only launch that low so I can get constant descent reaction times.

From now on though I could care less..I just want some good 60 ft times. 1.70 would be nice. No more points races just test and tunes for me.

 

Thanks man. Yea I'm sure it will pick up in better air. It doesn't like those hot humid days at all!!

 

Congrats on your new best. That's really impressive for a 3.1 engine. Good luck with your quest for that 11 slip.

 

Nice Mark, i see 11s in your near future. You will be knocking on 11.5s in no time I think. One of my friends got a 99 car with the 3100 in it and it pulls great stock. I will have to look at the weight next time I see him.

Your flying in that 3.1 though!

 

Thanks. Its still hard for me to belive I got it that fast the other day. 37 passes on the track so far this season.

 

Well im taking the week off racing and going to go on the 14th.

So I put the tail end of the car up on blocks today and when I had it in gear I noticed that I can not stop the tires with the rear brakes just while its idling.... I can hold it in reverse and 1st gear. But put it in drive with a warm idle and if the speedo goes higher then 20mph...then its not stopping no matter how hard I push those things...they just slow down.

That's not right. Could be a major reason why I cant hold that car at the line at all. Hence why ive been launching at 2100-2200 rpms all year long.

The brakes parts were all new as of 2013 and to be honest they don't look like they have much of any ware on them.

Every part on it is new. Including the adjusters, cylinders, springs...exc. Either the adjusters don't work right, or are on backwards.... Ideas?
Ill be honest I hate drum brakes!

No sence in pushing the car in the next few weeks or trying the 2 step a lot till I can get those things to work correctly.

 

Well thats not good. I dont mind drum brakes, but I didnt say I like them either. I did however find aluminum drums and put those on. They made a difference in braking, not alot, but I could feel them a little more. Next I am going to install the 19lb spring in the front of the prop valve and I will hopefully wind up with better stopping power on stock replacement parts.

Make sure some springs didnt let loose and check for leaks at the wheel cylinder. Check the shoes, they may be worn down but I remember you did them not too long ago.

 

I looked everything over. Shoes look almost like new still. Springs are where they should. The cylinders are new but they aren't leaking. At least u don't see any signs of leaking. I need to go mess with the adjuster. I really don't like the adjuster on them. But then again Mabey I put them in backwards. .. wrong side.

 

Seems like the shoes are way out of adjustment

 

agreed , just be aware drum brakes dont have stopping power of disc's what they have is holding power , so dont be to concerened about that not stopping the wheels from a high speed , but they should hold them from a dead stop

disc'c have stopping power from speed , but no holdin gpower on the line
drums have holding power on the line but not the greatest stopping power

chances are u just need to adjust the pads , or ur drums are to far worn and not thick enough

dont forget about using the ebrake while on the brake pedal on the line , doing that on my car i can hold my car at wot against the converter with no limiter

holding hte brakes in the burnout box also heats the rear brakes up alot cutting there holding power dramatically , this is why u should have a line lock for the burnout

 

Yea i always use the line lock in the box. I'll look into the car this weekend and hopefully get it straightened out.

Something is Def outta wack. My guess is the adjustment also

I'll have to measure the drums and see what the id is.

If I'm on the stands. Push the brake down and shift to d.... tires still spin. It's that bad.

 

I get fed up with my rears, over the years re-doing them or adjusting, never happy. This time around it’s been a few years, and the e-brake barley held the car anymore. So I get new pads n stuff, get em off and old shoes are the same thickness as new.
Drums look great…

So I didn’t change a dam thing just over adjusted them, till I could not move the tire by hand [put tire on a sec] so there was some good drag.

Ended up with much better rear brakes, my theory was to burn off a good layer of pad to make them "round" to each other for assured contact, seat them or wear them into each other.

 

I'm convinced it's just lack of line pressure to the rear. I even over adjusted them and still it's weak.

May try a few more things this week.

 

rear brakes by design hold a few psi in the line for quicker action, maybe they arent?

 

even with the E brake engaged?

 

The Ebrake does hold it a lot better joe.

I was just woundering if I have a clogged up brake line somewhere because without the ebrake it doesn't hold crap..... Id like to do the disc swap this year. I have backing plates already. Just need all the other parts.

Im going racing sunday. high of 64 and sunny. Not sure how much leaner im going to be as ive never taken it on a day less then 80*s But it should be ready for some good times.

 

if ya got 3 hands maybe you could un-do the release switch so you can just yank that sucker up hard and just let go to release

rear disc would be nice... could then get dash mount adjusters to balance it how ever you like, one setting for drag, another for street.

 

That is a good idea... might have to try that. Im dying for a 11 second pass and without those rear brakes working hard it might not happen. I used the ebrake the one time last year at the line....lol and it didn't drop when I floored it like I wanted it to. That was embarrassing.

 

maybe use a small bunji cord as a return spring?
so it yanks it down when ya let go, backyard fixin at its best

 

It is a good idea, I was going to pull the locking guts out of my ebrake. I have an auto so Im not really too worried about it.

 

u dont want the disc brakes unless u goto a trans brake , disc brakes will never hold ur car.

go get some s10 wheel cyls and a new spring for the prop valve , or gut the valve and put an adjustable one in it

 

Speaking of that, Mark I have a couple of those 19lb springs from Grainger for the prop valve mod. I am about to do that mod, it was reported that it works well for factory disc/drum setups. I'll give one to ya cheep or trade for one of those IATs ya got. Don't mind me, couple of beers talking before I work on this Volvo 850 turbo, lol.

The 19lb spring should hold better on the back with the drums. Braking power of 4 wheel disc, but because you still have the drums it should hold 1000x better than stock. I would def test them out to make sure it won't lock the rears before the fronts, but it shouldn't be a problem.

 

11.70 at 115.9 mph 1.64 60 foot.

No 2 step just old fashion foot brake. I'll upload vid later tonight.

 

Hell yea Mark! Gratz on hittin 11's! What boost level?

 

Thats awesome! thats a good 60ft time, too!

 

hell ya post up that video asap
so how does it feel to go from an 17 second to 11 second car ? u better buy urself a roll cage kit this winter

 

I was at the track when mark ran the 11.70, got a vid too. May post later, but he smoked this 87 formula with a 383, 1LE rear end, lingenfelter intake system, and some other goodies. Really got me motivated on my build for this winter.

 

11.70 @115:

http://youtu.be/WZce09mNhak

 

shall i give u a killer tuneup now so it runs 10;50's? lol

 

Congrats on your 11 second run, that's an impressive 60ft. Glad to see ppl still pushing the limits of the 660.

 

Thanks. Heres a better link of the vid and a slip/

 

Nice! Congrats on the 11's! How much dose the car weigh? Looks like it works great for a simple setup! Are you running the same tune-up as the 12.25?

 

Yes same tune as the 12.25 pass. But I worked on the rear brakes a bit so I could actually build some boost at the line. 7 psi on the launch. Car weighs 3260 on the scales with me in it.

 

Dave it felt amazing. A 1.64 60 ft was pretty damm cool for a v6
