We made it to the 5 last year tree times without hurting anything. We were slow but it sounded good. This year we will have the 44 amp MSD so we can burn some more fuel and take some more timing out.
Hope to have the car on the lakebed this weekend to atend the C/FR wars.
Mike, thanks for the help last week on the turbo engine, she rocked out 1683 HP and 1380 lbs. ft. of torque

Just as a point of reference, on my Early Olds, we ran 14.25 to l compression on straight alky. We then dropped the c. r. two points and lost 55 h.p. Then we put 25% in it and gained back the 55 h.p. plus 65 more. This was with a 435 cu in (394) olds. It ran 219 on methanol, and never made a full pass with the nitro without bearing problems, which is another story that took 5 years to solve..............Bob

It has been about 3 years since I talked to MSD about running their 44 amp mag for long distance applications, but back then they told me to look for 20 amp MSD units because the 44 amp would burn up. They told me there was no way to keep everything cool enough. What has MSD changed in the last 2 or 3 years that now lets the 44 amp Mag live for 5 miles? Is it time for me to sell my 20's and look for 44's? Thanks, Tom G. |

"Got'Cha" was first run in 1974. Bill Temple entered both 2 clubs in 1976 with records in AA/BGR. At El Mirage 201.79 and Bonneville at 220.
In 1977 Greg Temple started driving "Got'Cha" and entered the El Mirage Dirty 2 club in 1979 @ 201.97. Greg went on to set two records at Bonneville, one in 1981 at 241.848, then in 1991 he set another record at 262.230
Bill and Greg were the first father and son to enter the El Mirage Dirty 2 club. They broke the D/BFR at Bonneville in 1981 @ 241 with top speed of 249. This record still stands today. In 1991 they set the A/BFR @ 262 which was later broke by Duane McKinney.

I was told the same thing, but I am not a good listener. There are a few others that have not had problems to the 5. Mine is still on the dyno and hasn`t been to the track as of yet. If I can refind my tune with this thing I should have it at El Mirage this weekend. So far she is not coperating.

The best thing about that 44 is that if you crack your frame, you can weld with it!!!  |

Top Fuel dragsters need 44 amp mags because they are kept extremely rich to cool the motor. I have monitored the primary current and it never exceeds 11 amps on a normal run. Fred's lakerster went 355 with 9 amp mags. You do not need the big mags unless you are going to run 100 gpm pumps like the dragsters. The change from 15 to 90 % will change the A/F ratio from approx. 2 to 1. The smaller # is richer and the motor will run hotter not cooler because it will make more power = heat. The irony is if you run more % you probably have to increase the fuel volume to cool the motor.

I would think some sort of additional cooling might be worth a try. If the unit your talking about is what I think it is, there is no external heat sink, but I think the internals are potted in epoxy, so the outer case is in pretty good thermal contact to the case. Maybe an add on heat sink and fan would help the survival rate. Cheap insurance IMHO. |
