When I staged I lined up more to the left of the groove and that seemed to straighten it out. Maybe I was out of the groove when I was first lining up. I thought I was lining up correctly. The S10 went straight on Sunday with no problems. I did notice the S10 needs an anti-roll bar. When the truck pulls the front wheels, the truck is not level. The anti-roll bar will fix that.

I liked reading about this. Keep us up to date. Very clean little truck.

Update: Anti-Roll bar installed. Rear 4-link, front and rear shocks, front upper/lower control arms were removed, cleaned and greased. Truck is scaled and ready for the track.

Looking Darrell. When do I get to drive it?

Let me know if you plan a trip to Xtreme and we can talk about it.

While the S10 was on the lift I noticed the front driver side caliper was dragging. Passenger side wheel would spin freely but the drive side wheel did not. So, I ordered seal kits and rebuilt the caliper. It is a 4-piston Aerospace Components brand. Very good quality and easy to rebuild. Now the wheel spins like the passenger side wheel, no dragging.

Aerospace makes some really nice stuff that just works.

I finally had a nice day to go to the track and make some passes on the new anti-roll bar. Xtreme Raceway Park was open Saturday at noon so off I went. Made five passes and none of them were very good. I redlit 4 of the 5. On my 1st pass I cleared my delay box earlier and could not remember what my delay setting was. I was in the left lane and just entered a number in the box, stagged, light came on and I let go of the button. Truck rolled before I stabbed the throttle, redlight. Just cruised down the track. Got back to the trailer, checked by racers log and found the correct delay and entered it. 2nd pass, in the right lane, stagged, light came on, stabbed the throttle and it launched with the wells up. Redlight.



3rd pass, right lane, redlight.
4th pass, left lane, no redlight
5th pass, right lane, redlight

I never made a full pass because I hit my rev limiter each time way before the finish line. My truck settings are - transbrake (launch) is 4600rpm, shift at 6800 rpm and rev limit at 7400rpm. I run a 32" tall slick, 4.71:1 gear and a turbo 400 trans.

The next trip to the track I will set the truck up with - transbrake 4000rpm, shift 6500rpm and 7400 rev limit.

Hopefully the weather will change soon for the better. It is downright cold.

My last TNT at Xtreme had me thinking my 4.71 rear gears were just wrong. After more research I am thinking now my issue is fuel related. After doing some calculations about diff gear recommendations, the 4.71's maybe fine. I did find the positive and negative wires for the MSD box was not fully tightened. My fault must have got in a hurry when I replaced the box back last year. I was told years ago that the float level for E85 should be at half level on front sight window and almost to the top of the window in the rear. I checked and mine was right. I was also told I could run up to 7.5 psi fuel pressure before having any over pressure issues. So, I bumped mine up to 7.5 psi now.

Making and checking these made me think about my fuel pump and what its capacity was. I run a Magnafuel Quick Star 300. The tech sheet says it can handle 950hp naturally aspirated on race fuel but only 500hp on alcohol. Well, E85 is alcohol and I over 700hp. I am thinking fuel pump will need to be changed. I will verify when I go to the track soon. If I do need a fuel pump, I will go to the Magnafuel Pro Star 500. It handles up to 1200hp on alcohol.

Are you testing your e85 or is what your using spec mixed w/a data sheet provided?

Looking forward to seeing this one put some passes down.

Yes, I do test my e85 and it came out as e90 which is very good. Hopefully the weather will turn right for me real soon. I need to get some runs in because the season starts March 23rd at Xtreme.

If you watch youtube videos you can check this link out below and scroll over to 22:40 and watch my run against a big block 68 Dart.

No racing today. I was hoping to get to Xtreme Raceway Park for some TNT. But the weather is not going to let that happen. Maybe next weekend!!

[D.B]

New pump arrived - Magnafuel MP-4450 plus fittings. I will get it installed this Saturday so I can get to the track on Sunday.

[D.B]

Ok, the new pump is in and it runs with no leaks. I will be heading to the track tomorrow for TNT to see how it goes. Next Sunday March 23rd is opening day.

[HO455]

Good luck!

My day at the track was not as good as I hoped. I have a little ritual I do before racing. After unloading my S10 I always make sure the fuel cell is full and then I check under the hood. Want to make sure everything looks right before I get on the track. Since the sun was out, I took my race jacket laid over the steering wheel and I have a helmet bag the wife made that I put over the C2 bottle, shifter and delay box. Just to keep the sun and heat away as much as possible. When the announcer called us to the staging lanes, I put on my jacket and got in the truck. Started it, put it in reverse and started backing up and hit a barrel. How in the heck did a barrel get put behind my S10. I get out and was moving the barrel when the guy two spots over runs up and says he was sorry. He moved the barrel not thinking I was going to run into it. Well, the damage was done, the fiberglass rear roll pan was mangled. Since it holds my cut-off switch and charge ports, I had to leave it like that. Made first pass and hit the rev limiter before I noticed it did not shift into high gear. Second pass I changed the chip and this time it flew. Ran a 6.20 with a very sorry 60 ft at 1.43. Normally run 1.32ish. It pulled the front wheels fairly high and carried them out. So, wheelies slow you down if they are too high. As for the fuel issue before, there is not any issue now.

While checking under the hood I noticed the mounting tab on my coolant catch can was breaking off. So, I ended up zip tying it until I can fix it better.

I will get some pics attached of the damage and how I fix it for now.

Opening day is this Sunday so I will be fixing some things Saturday so I can run it on Sunday.

What time do passes start on Sunday?

[D.B]

I will be at Xtreme Raceway Park on Sunday March 23rd. Gates open at 9am and track typically goes live around 11am. Its opening day for our club, there should be a lot of racers show up.

[SCOTI]

Hopefully the wind dies off & allows for good/safe passes.

[D.B]

No Joke, the wind is really blowing today.

Ok, here is a pic of the broken mounting tab off of my coolant catch can. I had zip tied the can to bar at the track. The quick fix for now until my clamp comes in is to hose clamp it to the bar. I should be ok with it there for now.

[D.B]

And here are the picks of the damaged rear roll pan. I removed it while I try and find one. I did not notice until after I mounted the disconnect switch that it is now in the way of opening my tailgate. So, I am going to leave it for now until I fix the roll pan. It will make it a challenge to fill the fuel cell between each pass but oh well. That's racing!!
