Super Gas MPH
 

I am looking for a little guidance on understanding Super Gas MPH. I'm not new to bracket racing, just new to .90 racing. I am trying to select the right engine combination for my 1938 Chevy roadster.

I am leaning toward a 582 Chevy that would make 1,000-1,050hp. If that engine ran all out at say 7.90 at 167mph, how many mph would be lost due to the throttle stop when it's running 9.90? (ie would it run 9.90 at 164?) I'd like to have around 165mph if it's reasonable to do.

Thanks for any help.

Well It may be a little different with a full bodied car and of course it will also vary with were you use the throttle stop but as a point of comparison my 540/900 hp S/C dragster ran 7.70@170 off the stop and 8.90@166 on the stop so I lose about 4 mph (stop on at .5 off at 1.8-2.0 sec.)
Since your car is more powerful but heavier I don't know if my experience is a reliable indicator of what to expect.

p.s. If I could afford one I would have a 632 with big chief heads and run 8.90's in the low 180's There are a couple of advantages in doing so. First you keep you opponent in sight which makes it easier to gauge the closing rate and stripe. Second since they run harder in the last half they run much softer and more consistent in the first half.

Novanicks,
Too run the big mph in S/G you'll need a couple of things:
1). Plenty of Horsepower
2). Fairly light car (under 2500lb's)
3). Go on the stop very early and still be able to get the tree

Re: Super Gas MPH
 

Thank you guys. Very helpful.

Shake and Bake - to run 180mph at 9.90 how much HP does that take? Are there any other tricks to running big MPH other than HP? For example, I've heard timing retard on the big end can help, but I don't if that's say 0.5 mph or 2.5 mph.

Re: Super Gas MPH
 

Not sure I've seen a 180mph SG car yet but I'd imagine your talking 1300+hp
You can squeeze a little extra MPH by going on the stop sooner. In SC our first timer is set at .000. Sooner you can get off the stop sets you up with more track to pull.

J & S Racing,
Were you at the Summit Nationals in Norwalk ,Ohio last year or at the April Indy points Race this year? If you were you would have seen a
180mph+ S/G car. Just for the record....

310H Bob Handschuh SG 0 9.90 .041 1.494 4.487 6.618 8.428 9.958 147.130
w 3427 Rocky Clark SG 0 9.90 .034 1.697 5.183 7.159 8.698 9.958 180.190 .0076

Looks like +180 to me

Re: Super Gas MPH
 

Have to agree it depends on the set and the car. FWIW my S/St car went a best of 161.2 in S/St. All out its best mph was 170.7

Donnie pedan ran 9.90 @ 192 at baytown few years back.

Re: Super Gas MPH
 

Did Donnie Pedan run IHRA Super Rod?

Nhra sg

Re: Super Gas MPH
 

nickh,
What month and year did he go 9.90 @ that mph?

Re: Super Gas MPH
 

It was probably 7 years ago ,same event that Michael Manners ran his blown alcohol dragster in super comp running 8.90 @ 223. Why?

Re: Super Gas MPH
 

Just curious. Wanted to look it up...
Thanks.

Re: Super Gas MPH
 

I am friends with Donnie on facebook will ask him the year, he was a huge help to us when we ran top sportsman and quick 8 stuff in division 4. If you are in division 4 go back to 2005 we ran a 95 Jerry Haas Monte carlo and were sponsored by Royal Purple.

Re: Super Gas MPH
 

I'm in division 3. But I'll check it out.
Thanks...

Re: Super Gas MPH
 

nickh,
Did Donnie ever get back with ya on what year he ran that big mph in S/G?

Re: Super Gas MPH
 

wow,that is one bad *** s/st car

Re: Super Gas MPH
 

How about "present day" mph in S/G or S/R East-to-West coast.....Say the past couple of years.....

Re: Super Gas MPH
 

Not scientific by any means, but this question had me curious so I checked time runs for 2-3 divisional races per division from 2016. Nobody is head and shoulders above the rest. Rocky Clark was the highest I saw at 178, and didn't see anyone else above 175. There are a few guys in the 173-175 range, and then a whole lot of 170-172.

Lenny,
Found these rounds from the 2015 NHRA Summit Nationals in Norwalk.

Car#-Driver(Opp'nt)-RT-----ET-- Speed
3427 Rocky Clark
E3 2.048 9.907 183.59

Prior rounds:
E2 (T Hack ) 0.001 9.900 0.000
E1 (K Brannon ) 0.004 9.937 0.037

Qualified: #15 9.937 0.037

Clark had some kind of a problem on the line and an easy win for Vrooman.

Thanks, but I saw that the first time you posted it on page 1.

Re: Super Gas MPH
 

lol!

Re: Super Gas MPH
 

I'm to lazy to look it up, but i know 4 to 5 that's been 190 plus in SG

Re: Super Gas MPH
 

I'm sure a lot of these top sportsman cars could throttle stop and be around those mph marks. That's what most of these high mph cars are anyway, that and ex pro stockers, it has gotten crazy out there!!!!!!

Joe,
Come on man! What else you going to do when it's 20-deg. out?
Dig man, dig......
