OT: So, You Wanna Build a Street Car?

[Old Guy]

Drifting tangent here. My brother and I, back in the late 80's, were trying to revive a bedraggled early RX7. Unbeknown to us, the dealer parts guy gave us the wrong ignition points. We got it going (it was totally dead when purchased) and, as males tend to do, jumped in.

Car behaved erratically. A couple of stops, it was improved but still not right.

Down towards Ohio State campus, just east, was a poorer working class neighborhood. Such were more hospitable in those days, crack was barely known, and heroin not to be found except in REALLY bad places. So we thought nothing of going thru.

We stopped at a corner for traffic. It cleared and we pulled outwith a godawful backfire. Young gentleman with his back turned to us went several feet in the air. Considered stopping and offering to pay his dry cleaning bill, thought the better of it.

Eventually did trace it to wrong part, dealer made it right.

not as bad as my boat link.

I guess as long as it's not a Four Wheel Drifting tangent we are OK.

Now this is a fast car driven by a guy who knows what he is doing. Audi Group B car from about 1986. these two old guys are doing a demo in 2010. Forget drag racing, this is the real deal; just never caught on in the US.

We like turbos!
I replaced my big block with this last winter. Wanted to move into the 21st century with fuel injection and turbocharging.
Car is a 69 Nova



This is an alum 5.3 from an 06 Silverado SS pickup.
76mm turbo. Runs on E85
Quite mellow, until the boost hits.
Street/strip car and so far has run 144mph in the 1/4 mile.
Approx 850hp at the crank.
15 psi
GM electronics. All built and tuned by me.

Very Very Nice Ron !

How are you getting the GM computer to inject enough fuel for 850hp or can it handle it automatically? My understanding of mass airflow fuel injection is limited, even less so than my limited understanding of speed density fuel injection. Most Volvo hotrodders use Megasquirt speed density kit computers on their ancient turbos.

Ron, that is one hell of a cool set up and in a 69 Nova - love it !!! Pic's of the car please....

[RonSSS]

Thanks guys. Appreciate the kind words.

Volvo,

The GM system is a combo of mass airflow and speed density. I use tuning software called HP Tuners that changes the stock operating system to a custom 3bar speed density system. Fuel flow is determined by injector size. In my case, 110 lbs/hour. It works very well. The PCM came from a 99 Camaro.

Here is the car last year with the rat fogging the bags.



The best it ran before with nitrous was 9.40 @ 143. I've bested that mph with just a handful of runs.

The short block btw is stock with 136k miles on the clock. I only opened the top ring gaps a bit to accommodate the heat from boost.

Pretty fun. And I can turn the boost up when I have the balls to do it.

Well the title does say OT does it Not ? No Worries if you drift too far you will be told...


Ron, What do you have in it for trans,rear gear ? And it is street legal correct ? Awesome job you did with the motor !
