Re: Street Car RWHP/TQ

I have a 720ish whp V that grandma can get in and drive, or I can go click off low 10.20's with ease. The dyno was used as a tuning tool only, quite necessary as we know. My '66 makes unknown hp, but I'd guess around mid 600's flywheel. The car will definitely keep your attention, and grandma ain't drivin' it. The car will likely never see a dyno, but would be interesting to see whp on it.

Re: Street Car RWHP/TQ

Sorry I went off-topic above. The "600" comment is the magic number that it would take to get me to consider a BB for the next upgrade from where I'm at now rather than the current considerations, which are also off-topic. (boost or more cubes... or both) Either way, it's getting expensive to go up from here!

As for the timeslip, I'll find out at Dragway 42 at the Northern Ohio show!

But I got him at the light my .235 reaction to his .685.
I turned a 1.728 60 foot and 8.0 1/8 mile to his 2.146 60 foot and his 8.3 1/8 mile et.
I only won by .0595 seconds but it is a win in a heads up drag race which is what we were doing.
First one to the end wins.




I do agree 600 wheel HP would be ridiculous in the right car.

I think there are 2 lessons here: A) you were a better driver with reaction time of almost 1/2 second and you may have shifted better during pass; B) second your car was better suited for what you were doing via the 60 foot. I think that a lot of times a bad 60 foot can just continue through the whole process. So practice and make sure your car is set up for what you are trying to do or at least be in ball park. These guys show up with the powerful cars with street tires and can't launch or have to back off on the throttle then go back on etc. Plus I think the hp is only part of the equation and low set of gears (assuming you have traction) can do wonders for the et.

Was this his first time at the track? I wouldn't expect him to stay that slow for long if he has any desire to practice and get better.

Re: Street Car RWHP/TQ

He had been many times to the track racing. I asked him 3 weeks before the race if he could drive and I have been in the car with him during a quick drive and he does well.
That light thing is an art.. my wife is always in the .0?? area for reaction times.

That Mustang had to have the transmission fixed under warranty. and then a week after that racing he discovered rear wheel bearings were out. They were making some bad wobbling issues. Independent rear suspension.

Time to sell it.. his best ET was 12.2.
His dad just purchased an early Nova with a 6.0 LQ9 bored out with LS3 pistons and LS3 heads and a smallish cam and carburetor. 373 gears and it was clicking off 12.0 et's with one of the rear jets laying in the holley fuel bowl.

He raced his dad and his dad cleaned his clock time after time.. so that led to the sell also.

I drove the Mustang and drove it hard myself and the hole shot was just not there. The power once you got it to 4000+ RPM was amazing for a 5.0 and you better be quick on the shifter with that 6 speed standard with 3.73 rear gears.


I told him for 3 weeks I was going to kill him out of the hole and he would have to play catch up.
Happened just like i told him.


I did cheat though I pulled my RPM intake and HEI off and stuck on my tunnel-ram and single point distributor and added my Coan 4500 stall and my 4.56 gears with a spool and some hand me down Nitto 555R tires 275-60-15 on 5.5" wide steel Ford truck wheels.
Like said it is all about the combo.


OH The wife and I drove over 100 miles round trip in the car to the track and back home.. Nice way to spend a Friday night. Not so much a 100+ degree Friday day though.

Question was about a street car, it has evolved, as usual, to many other things!

225-250 is plenty for a fun, street car, IMHO👍

I made 275rwhp from a $300 junkyard 5.3L all stock except intake and headers.

That was pretty boring IMHO, even with the manual transmission. It might have been OK for a daily-driver or something on hard 15" radial T/As, but not any fun for a "toy" that gets beat on with sticky-ish tires. It wouldn't even scratch 2nd shifting off the limiter on 315 Rivals. The gas mileage was fantastic though.
