Dime Rocket- DNQ

GTOMayhem · 05-27-2015, 08:30 AM

I may be the only other person interested, but I have a ton of questions. Mark knows why.
What wheel /tire combo up front? I see the spare wheels with skinnies on the rear.
I also see the single belt. Did you replace the steering rack or just bypass the pump?
What did you use for headers? Over the counter? (I somehow doubt it) Or custom? Not asking for secrets just an idea, as I have had a number of ideas to improve on what's available for this type of car.

Hi Rick,

Those are 22x 8 Mickeys on 15 x 7 mags we found in a U pull it yard.
The car came with 16's so the calipers needed a little "adjustment".
You nailed it on the rears. We will probably put tall ones in the rear when we come across some.
Yes , the original rack has the in and out tubing spliced together to hold some fluid in.
Much too fast a ratio, and very hard to steer with the slicks at low pressure, but I don't know what to do about it.
We made the 1, 1/2 , to 1, 5/8 step headers, using pieces from Speedway, and merge collectors off of Ebay. We had a local chassis shop water jet the flanges.
The overall length , basically was determined by the constraints of the front header exiting in the r.f. wheelwell. They are all welded...No tethers!
Thanks for your interest.

Awesome pics, thanks Mark. I was trying to figure out how to get equal length in this type of car. I was thinking of adapting full length RWD headers to exit the fenderwell, but was wondering about legality. Your solution is much more elegant, if you can use that word concerning a dime rocket.

I figured the steering would be difficult. I was thinking of running the power steering pump with a water pump motor. Have you or anyone you know tried that? Again I know this is another of our issues with a heavy FWD car.

Some taller rears should help with keeping the weight on the front. The W-bodies, Impalas and Grand Prixs can be raised in the rear using the variable rate spring from the Olds Intrigue.

Interesting headers Mark. Looking at that last photo howerver, I hope you never pop a head gasket!! Should be good for keeping the tires warm though....

Huh! Never thought of that.
...Been doing them like that since the 80's.
Not too many other good options on some of these things.
I suppose it would be worse for a RWD to grenade a transmission and have the oil go under both drive tires ;-)

Mark,

Are you running factory ECM or aftermarket EFI? If factory, are you using only one O2 sensor?

What mods to the transmission?

Rick , It is a factory computer reworked by Ed Wright.
Timing and fuel curves moved around, limiters and shut offs set at a high value.
No O2 's , no EGR, no vapor valve, etc are hooked to the computer.
LT1 adjustable fuel pressure regulator..That's all.
No electric trans signals of any kind...It is a mechanical T 125 C 3 speed.

.

I have been searching for a receipt since I saw this last night to get a name and number. But cant find it. I have to get ready to leave for Div 3 race in Joliet this weekend. When I get back next week I will look some more. But I had a power steering rack modified to be used as a manual rack. Not the same car as you have here but it was a GM car. In any case they were able to change the ratio and it worked out great. Like I wrote I've run out of time. But I will look some more next week and try and find it. Good chance they could do one for this car too. And it was not too expensive. If I remember right it was a couple hundred bucks.

Thanks, Rob

Might be interested in that...as long as it doesn't put over and out of the D/R designation.

Good luck
