By your MPH in the 1/8th, I'd say you're capable of low 5.0's in 1/8th.
(the 60' are slow but you have a handicap with the small slick)

I'd say you're getting it lined out good.

Thanks for the reply.

The time slips have 60', 330, 1/8, 1000, and 1/4. I just did not post them.

I looked at the 1/8 mile passes when the gave me 1/4 times Friday to compare the runs to the 1/8 mile passes on Saturday. That is how I knew I was still to fast for the 8.5 index on the 1/4.

I can use all the help I can get, thanks

Good going, Glenn. You're making great progress. I wish I was half as far along with my blower conversion.

Good luck.

So after 40 days and 40 nights of rain and cold weather it looks like we might get to go to the track tomorrow. The dragster has been wanting to quit running at the top end of the track (fuel running away from the pick up) so I have been wanting to install a primer system



I purchased a "Kit" that used Enderle's billet tank through AlkyDigger



To do what I want which is a little out of the box I had to purchase some additional stuff



So this install made me really nervous as it just seemed to fall together, normally you have to fight and fit things many times but this just seemed to go together. The return from the "K" valve was just the right height of the bottom of the belly pan



I removed the two plugs from the side of the primer tank and two -8 fittings screwed right in, I removed the straight 1/8 NPT to -4 fitting out of the bottom and installed a 1/8 NPT 90 -4 fitting on the bottom. On the -8 fitting I installed a -8 coupler.



So the tank is just the right height so that the bottom fitting just sits on the belly pan, the -8 return on the tank is just the right distance from the side of the chassis and bottom of the belly pan. The wiring from the old electric fuel pump was in just the right location to connect the primmer pump. With it plumbed into the return line from the "K" valve the tank will always be full once started for the first time on a race day. That just makes one less thing that needs to be done in the pit.



I replaced the old fuel pump toggle switch with the rubber capped momentary on starter button ordered from Summit, and now at a push of a button I get a nice squirt of alcohol into the rear most port of the hat on top of the blower. I had used the rear ports in the blower for my rear two injectors. We will try it out tomorrow.

Any sort of heavy-wall hose should be way better than the clear plastic stuff. Nothing is 100% fireproof....you're just trying to get the hose to hold together longer than whatever else is going on with the car.

Hope this helps,

Update: we got some of the recommended McMaster Carr hose and didn't like it. The ID is a bit on the high side and it wouldn't clamp securely. It's all in the trash can now and we switched to the NAPA 605 stuff. Much better fit.

Well it has been awhile since I actually posted anything on the dragster.

Well it has been raining, raining, raining, and more rain.

I did get out two weeks ago and really hope to get out again tomorrow to do some more testing, but it looks like rain.

It is really important to get out tomorrow as I want to go to Norwalk the 20th for an NDRL race. The problem is that, one it is an index race and I have not gotten that squared away, two it is a pro tree and have had no practice on a pro tree, I may go anyway to get away from this RAIN (and yes I am tempted to use a forbidden word here), and three it is ¼ mile and lately for one reason or another it seems all my racing has been 1/8 mile, I hate 1/8 mile.

Went club racing Friday June 21 club racing 1/8 mile. Here is a summery

First run, Friday night 8:23 PM
Air Density 2200
Top Pulley 60
Pill 90
Fuel Pressure 60.38
Top end Boost 9.02
60 foot 1.316
Calculated ¼ mile 8.443
A/F ratio 3.808
Comments, I did not write down the pulley size and pill so this was done from memory, data is questionable.

Second Run, Friday night 9:22 PM
Air Density 1810
Top Pulley 62
Pill 90
Fuel Pressure 59.82
Top end Boost 8.31
60 foot 1.303
Calculated ¼ mile 8.586
A/F ratio 3.810
Comments, This is really unusually good air. Took away some air, but the density go better the end result was little change

Third Run, Friday night 10:15 PM
Comment, I had to throw this run out (won the race), dew had fallen and after the 1/8 mile marker I had to get out of it as it got really squirrely (rear tires started to spin in the dew on the track). Data was all screwed up and graph was useless.



Ok, now Saturday, Gasser series racing, June 22.
Gasser series is 1/8 mile ET racing, so I have no ¼ mile times (so for comparison a ¼ mile 8.483 is a 1/8 mile 5.427). We only had two time trails as there was a bad accident that shut the track down for awhile, the guy is ok?, but will be in the hospital for awhile.

First round of qualifying, Saturday 3:07 PM
Air Density 3079
Top pulley 62
Pill 95
Fuel Pressure 51.61
Top end Boost 7.53
60 foot 1.312
Cal 1/4 mile 8.702
AF Ratio 3.688
Comment, Felt terrible, to slow for the 8.5, fuel out the pipes, need to make big changes

Second round of qualifying, Saturday 4:35 PM
Air Density 3249
Top pulley 60
Pill 105
Fuel Pressure 52.06
Top end Boost 8.31
60 foot 1.265
Cal 1/4 mile 8.392
AF Ratio 4.074
Comment, Much more like it, but now too fast. This run was against my arched nemesis (a good friend who in the second round of eliminations I give the race away to by breaking out and red lighting). I had my best light ever a .508 and beat his ET by .1865, now if only I could do that in a race.

Ok, now we are into the first round of elimination so we decided not to play with it and see if we could predict an ET.
First round of eliminations, Saturday 6:13 PM
Air Density 3100
Top pulley 60
Pill 105
Fuel Pressure 50.99
Top end Boost 8.24
60 foot 1.247
Cal 1/4 mile 8.410

Comment, Treed him and won by .0281.

Second round of eliminations, Saturday 7:41 PM
Air Density 2858
Top pulley 60
Pill 105
Fuel Pressure 53.28
Top end Boost 8.31
60 foot 1.241
Cal 1/4 mile 8.355
AF Ratio 4.110

Comments. This guy and I end up racing each other a lot as are ETs are always close. We have yet to have a race, we each keep giving the race to the other one, this time I red lite and broke out. The dragster sounded good and felt good, it likes this air fuel ratio better, but once again I am too fast for the 8.5 index.

Serious consideration is being given to going in the other direction (8.000 index). The problem boils down to engine RPM. I am concerned that this engine will not last if I push the RPM higher, currently turning 6400s at the top end. This is a stroked Pontiac 400 punched and stroked out to 461. A simple fix would be to put a higher tire on the rear. I am currently running a 31X13X15 M/T. by going to a 32 high tire I increase the circumference by 3.96 percent (drop the top end RPM by 253)(circumference 97.0 to 101). No one makes a 32X13X15 tire Hoosier has a 13.5X13.5X15 in a lightweight C07 compound, but the side wall will not clear and I cannot space it out as the tire rim combo I have now is spaced out, so I would have to buy rims also. Hoosier also makes a 32.0X13.0X15 in a D05 compound which is a soft compound and one of the problems is I have low HP and based on the graphs I am dead hooking now. M/T makes a 33X10.5X15 tire with a M3 compound (medium). This tire is interesting in that the compound is a little harder, the with is smaller so it might help with the launch, but I afraid that I do not have the HP to turn a 2 inch taller tire. INPUT REQUESTED

Tuning, it I stay with the 8.5 I think I want to try a 110 pill and adjust pulleys to get an A/F ratio of 4.1. By taking away more fuel and keeping the A/F ratio about the same I should take away HP and slow it down a little more. Sure would like to go to the 8.000, but have the RPM / tire problem.

[Tom Vaught]

Good luck on your program, Glenn, making good progress.

Pulling for you all the way. Took Marty a bit of time to get dialed in with his Pro Mod on alcohol, both driving and tune-up. You will get there and make us proud.

Well we really wanted to test this weekend as I would like to go to Norwalk for NDRL

Briggs and Stratton Summer Jam
at the Blue Suede Cruise
Summit Motorsports Park
Norwalk, OH

http://www.frontenginedragsters.org/...php?topic=48.0

We still do not have the 8.5 index straightened away and kind have hit the physical limit of slowing down with air fuel mixture (top pulley cannot be any larger without changing the belt guard and the bottom pulley is a 42 tooth pulley and has the drive for the belt for the fuel pump inside).

We have made the adventurous decision to go for the 8.0 index instead.

Empire was rained out Friday, washed out Saturday, so we decided to drive two hours to go to Esta Safety Park Dragstrip‎, 8091 Eastwood Road, Cicero, NY 13039. Got up at 5 in the morning to leave by 6 (two hour drive), got within 10 minutes of it and received it was closed due to flooding.

Plans now are to blow off club racing July 12th for testing for Norwalk.

Can you keep your 8.35 tune up and lift at the mph cone and coast to an 8.50 or close? With both of you leaving at the same time you can probably tell which one of you had the better reaction time. If you think you left first, you just have to drive the finish line and keep a wheel on the guy next to you. If you felt late you will still be right there with him being you can run faster than the 8.50 index. He will think you had a better reaction time than you really did. Get to the end and lift or hit the brakes and let him cross first. He may go faster than the index and break out handing you the win. Just another thought as how to hit the index without messing with the good tune up. In most index racing you will find most can run faster than the index as opposed to trying to tune it to hit it just right.

Two reasons I would not do that, one it is not consistent/repeatable, and 2 I would rather run flat out than drive according to the opponent. I want to run my race not his.

[Probird]

I wondered if that might be your mindset on racing. Nothing wrong with that. To each his own. I didn't kow how competitive the class you wanted to run is. I'm all for going fast but I also like to win races. It was just a suggestion to win some rounds. Good luck!

[GTOGEORGE]

Sand bagging a 8.30 car is tough plus you need a good set of brakes. All someone has to do is tree you and you're history. Keep working on your tune up....... You'll get it.

I agree

[GTOGEORGE]

Glenn,
If you were running carbs and a electric pump, I could get in the ball park on you're tune up like right NOW!


GTO George

[johnta1]

Couldn't you just close the stop for full throttle on the scoop?
(less opening)

Seems like it would be easy to limit the opening enough to get a slower ET.

I was running a carb, and could not get there (8.5, best was 8.59) that is why we added the blower

I do not see why that would not work.

Still would like to get the A/F ratio right so it does not sound like a truck.

I do not know why I hesitate on this it would slow me down

Best guess is this is also an educational process to learn how to tune, and I should be able to do that. I am really leaning to go to 8.0 (faster)

Have just developed a side problem, the tow vehicle on the way to Cireo sunday throw a code, reset the computer and it drove fine the rest of the way there and back once we found they were closed because they were flooded.

The dealer I normally go to cannot get it in to pull the code until tomorrow and has a two week back log, called every dealer here in Rochester and they are all the same for diesel stuff.

I have been toying with the idea of an RV to go to the tracks with and have been looking all morning and found I know nothing about them. Thinking I want Freightliner chassis, 350 HP diesel.

This is the wrong time to buy such a thing and RV (camping world) are snobs now because they are fat

I really wanted to go to Norwalk but do not know if that is possible now.

[johnta1]

There seem to be a lot of cheap RV's here in Florida.

Well did some test and tune today to work on .400 Pro Tree and 8.50 index racing. Been working off and on on this for awhile now with not too much success. The vehicle has been too fast and I have been too slow.

The plan is to go to the NDRL race at Edgewater Sports Park Cleves, Ohio in two weeks. I have never run a pro tree and an index so this will all be new to me.

A great day of testing, we are in the ball park!

[johnta1]

Good looking RV, Glenn!

Looks like your ET's are getting lined out better.
Never can have too much testing/tuning.

[SupergasDil]

Let's see some pics/ vids of the car on the track.
