E85 and our trip to the track

Postby 2lucke4u » Sun Aug 27, 2006 9:11 am

Hi Guys
Made it to Byron Dragway,sort of,our tow vehicle colapsed its cat on the way and it was like driving backwards,made it there late and got three runs in,,in short ,Byron SUCK's,,3 hr's 3 runs,,the track was so slippery I have video of the car spinning its 9 inch hoosiers to the 1/8 mile mark,never had time to tune because we could not get a baseline run down,,flahed the converter off the line in the opposite lane and spun to the 60ft mark let off ,and hooked a little, and time suffered greatly 12.50 with a 2.501 60ft,if you remember the car was running 1.7's,which is poor to start with, and we lowered the control arms and put in frame connectors for this trip to the track,back to Cordova next week,tried mixing E85 with premium gas at a 25% ratio,has anyone tried this yet,we were not down in the horsepower department,overall we had a good time talking to other racers in the staging lanes and looking at cars,people loved the tc,weighed in at 3000 with driver,keep you posted on Cordova trip,,has to be better,,,

E85

Postby v8vegawagon » Sun Aug 27, 2006 11:55 am

I'm sneaking up to 100% E85, I'm at 30% now. I am trying to find the correct jetting as I go, don't want to get too lean. All is looking good right now will probably try more E85 this coming weekend. Several racers out here already run 100% and are very competitive on the divisional level.
And I thought 2 litres was a bottle of soda pop !! It ain't cheating it's creative use of the rules.

Charles, have you tried Tri-state raceway in Earlville IA? Buddies of mine rent the track once a year and everyone has thought that it is a great facility. Looks like its only 30 miles from you.

Yes have raced there in the past,,they have no test and tune days this month,,track is ok ,,like the people,,I will be at Cordova Il this Friday ,,I'll be putting my 390 gear in for testing,,I need to scrub some speed off the line,,the car made its best pass at that track while popping at high rpm,,the nos system is hooked up with a 50 shot,we have jets for 75,100,125,150,175,up to 400,if we get the tune right we will try the bottle,,we feel on the bottle low 10's will be no problem [traction permitting] let you know how it goes,,

Charles,

I generally get my best hook and times at Byron. I guess I want to know what you mean by "lowering the arms". If you lowered the rear lower control arms in the front (at the chassis), you extended the instant center to waaay in front of the car, and killed your hook.

Hey Chuck
I lowered the control arms on the rear end side 2.5/8, we will also be dropping the front end by cutting 1 full coil,,hope to drop it 2 inches,,number one comment was,"nice car, never seen one like that", number two comment,"why so high in the front",,
the car sit perfectly level right now so we hope to give it a little rake,,with the 90/10's up front and the new springs this sucker is tight on the front end,,you cannot push it down,,don't know if thats good, or bad, but three different tracks, and the same comment, time and again,,any thoughts on this,, cordova looks like a sure thing for Friday,,they have open racing from 5:30 on and midnight mayhem which runs untill early morning,,anyone in the area going????

Charles,

What springs are you using now? If they're V8 springs, cutting coils will only make them stiffer. I would recommend finding some 4 cylinder springs. They should drop the front end and keep some stored energy for the load transfer with those 90/10s on the launch.

springs,,,trip to cordova,,

Postby 2lucke4u » Sat Sep 02, 2006 7:58 pm

hi guys
cut 1.25 coils out and the front dropped 2 inches,,yes its too stiff,,need some 4 or 6 cyl coils,,all the cutting, lowering and such and we still ran 11.97 @ 110mph,,got air with the fronts,,still broke loose and spun,,blew the egr valve and sprayed the windshield with oil,,that ended the night,,ever try getting oil off your windshield??? with the lights at the track we could not see clear enough to race,,I was in round two of trophy eliminator and hole shot the guy,, had him beat, and had to shut it down,,he waited at the end of the track for me to see what the problem was,,thanked me for the win three times,,he agreed that it was not worth it to take a chance,, we had a good time,,need to find a soulution to the oil coming out the valve covers,,both the egr and the breather,

Charles,

Congrats on the 11! If you're getting air on the launch, when is it spinning? What size and brand of slicks are you using? At what point are you hitting the nitrous? I assume you mean you're blowing out the PCV valve from the valve cover. Since that is blowing out and the valve covers are blowing oil enough to coat the windshield, you have a major crankcase pressure problem.

What did you set your ring end-gaps at? I don't remember what size your engine is, but a 350 with nitrous should have a top ring set at .026", the second ring is still good at .016". Could the ring end-gaps be lined up on one or more cylinders? Has this been a problem from the beginning, or could you have had a lean nitrous pass? A broken ring land could cause cylinder pressure to bypass, as well.

no nitrous, all motor,have not tuned enough to use the bottle, 383 stroker,,hoosiers 15 x 9 , brings front end up and gets about 5-6 feet out and breaks loose and I feel it slide a little,,have a 390 gear on a titainium spool,have zero gap rings installed by the book,,pvc valve blew out the valve cover,,both pvc and breather are at back of valve covers,,we run 80lbs of pressure on the launch and some think we are filling the back of valve covers with oil as we leave the line,,we will be moving both the breather and pvc to the front ,we will be checking cylinder pressure today to see whats up there,,any ideas ,,,,,thanks for the reply,,

Charles,

If it's spinning 5-6 feet out, have someone videotape the launch. If the rear suspension separates at launch, which it should be considering your lowered arms, it may be topping out the shocks. That sudden jolt will break the tires loose. I would suggest to either get longer shocks, or adjustable shocks able to stiffen extension/rebound. Those Hoosiers should bite well. What pressure are you using in the rear?

Is the cam a solid or hydraulic? If it's a solid, you may want to consider oil restrictors to the lifters. This will limit the amount of oil in the valve covers. The only downfall is you need to remove the trans, since they install in the rear plugs of the block.

problem found???

Postby 2lucke4u » Mon Sep 04, 2006 12:09 pm

Chuck
The hoosiers were set at 9.5lbs,did a compression check,,#8 has 65lbs,all others have 165lbs,,,whats your guess,,bent valve because of the rockers adjusted too tight,,or rings? my guess is bent valve because the rockers were turned down a full turn before we figured it out,, in any case high 11's with a bent valve is not bad,,I expected the car to run 11.50's on motor ,now we know why it did'nt,this could also explain the oil problem,,keep you posted,,

loosen both rockers on the cylinder thats bad then put air into that cylinder through the spark plug whole and see if it leaks out the carb or the exhaust that will tell you if it is a valve or someting else.

valves

Postby 2lucke4u » Mon Sep 04, 2006 6:33 pm

I'm guessing its an exhaust valve,,what would explain the high pressure in the valve covers?
