Front Engine Dragsters / Re: What did you do on your Front Engine Dragster TODAY?

« on: July 23, 2013, 07:56:44 PM »

When we ran our engine on the dyno it was with collector headers to get the exhaust out of the dyno cell. I guessed the dyno headers had to be worth 20-40 hp. I have always ran zoomies . We have several nostalgia cars in our group with modern scoops, carb(s) and collector headers. If it were up to me it would be stack or hat injection or blower, any fuel , no intake scoops and zoomies only. The lack of a delay box and model year largely makes a nostalgia car with our group. Oh, and your dial must be 4.99 or quicker.

My checkbook won't support it but I have seen the the MSD chips in the JR fuel cars. It's above 10,000.

I'm a Ford guy, racing partner is Mopar for sure and we have a SBC in the car.

 It's a good compromise.

Are you serious ? A wing behind the driver on a FED?

Front Engine Dragsters / Re: How do i get my chassis certified

« on: July 12, 2013, 05:08:44 PM »

Mine was built in CA ,brought to MO,where I bought it. Brought back home with an expired sticker in it , only to find out it wouldn't have passed in 2000. Funny thing about it was the sticker was a 2003. It was a lot of work to bring it up to SFI spec. All is good now with a 6.00 cert.

Good luck with yours.

Larry,Many tracks arrange chassis inspections ahead of the season's start. My home track (Havana Illinois) had one in March. You could call the NHRA division office and find out where the chassis inspectors are located and contact information.

Have you used an SFI spec guide in your build? If you haven't , you might be wasting a $$ trip. The inspector will charge mileage and the inspection fee. My first chassis cert cost $ 260.  second was $ 150.

Test cell (dyno) probably more appropriate than track for such comparison.

Yes sir. I'm sure someone has done that. I just haven't been able to find them.

Although, my stuff has been on a dyno  it's two different worlds. That is dyno vs. race track. The dyno loads the engine harder than my car does.

Wide open, I have run both and have seen no difference. Lots of variables. I was looking for others to share their information. Like plug gap.

George the MSD parts are

Box  6AL      pn 6420
Coil  HVC II  pn 8261
Distributor   pn 8517
Crank trigger
2 Step        pn 8739

Our engine is a 12.5 to 1 462 Buick that is about 850 HP and 673 ft/lb on a decent tune with carb and race gas. We now have the 4port Hilborn as a throttle body with 8 Enderle nozzles at the valves on methanol so it should run pretty good in a 1200lb car.
What is your build?
John

John. Our engine is a SBC 4.030 X 3.48 . Dart 230 iron heads.Shaft rockers.  Ross pistons 13.4:1, Scat 4340 crank, Callies steel rods.Custom roller cam, Hilborn 2 7/16 on alky, Waterman 400 pump. Dynoed 641 hp with MSD 6. Now using MSD 12LT mag. Last time we scaled it we were 1480 wet with driver. I have added a few things since that weight -in. Probably closer to 1500 now. We ran a 5.10 in testing Memorial Day weekend but have been rained out in every other outing this year. July 20th is our next attempt.

George we run a spark gap of .018 for the mag and a gap of .050 on the MSD we use the NGK race plugs. We will most likely go up on the gap with the 16V battery installed. I do have a resistor for my gauges and trans brake. I am going to check with Race-Pak to see if I need to use a resistor for their products.

That was a good link on the 16 Volt battery.    We  are using the XS Power D-1600 deep cycle for our car. We are also using the Tilton high torque starter.

What MSD box are you using ? Coil?

Supercat. Thanks for sharing. George

What are you using for ignition and what is the plug gap?

I found some helpful information on 16 volt systems: http://www.dragracingonline.com/technical/v9-battery-1.html

Thank you again for sharing. Not many have shared information in this thread. My car is for sale and in my next project I will be using a 16 volt battery. As for the mag or no mag question , I'll start with the MSD digital 6+ I already have. If it's a problem the plug gap will get  smaller until that's a problem.

George I don't know if this will help you but I run a 7al3 box in my car and have had no issues at all with it . My motor has 14.8 compression on alcohol and we have sprayed it with a 250 shot of nitrous . I really have nothing to compare it to as I have never tried a mag in mine

Thanks for the input. What battery do you run? Do you use it to start the car? Spark plug and gap?
