What would it take?
 
SBC 350/255 to run 10.70's in G
How much HP or what is the most HP one has made?

LOL, I'm bored at work

Jamie my guess is it would take about 20 grand lol, hope this helps!

LOL, You are dead on about the money figure:)

Jamie / HR9121,


More like $ 13-15K if you have cores ? That's not a cheap combo to build.
Good Luck & take your Time , you can still have Fun & Win going 5-6 under !!!

Dave, It was a Hypothetical question. I have a 85 camaro with a little 305/263. I hope to make it 5-6 under, LOL.

This is one of my favorite web sites. Ive killed hours playing on it. Everything is pretty much spot on. Except the ".Compute ideal MPH and times at 60', 330', 660' and 1000'. They wont match your cars times for some reason. But they are proportionally correct.
The "ET - MPH - HP Calculators" in the first column. And the 'Gears - Tire - RPM Calculators' at the top of the second column are my favorites.
Hope this helps.

Basing it off my car (chevelle with 255/280 in h)

Went 11.66 at 3405, with 384 flywheel hp.

-140 lbs for to go to safe g weight = an approximate 11.52

so thats about .80 required to go 10.70's

at roughly 10hp per tenth like a slide rule calculator, you'd need 450-460hp.

Correct me if i'm wrong. And yes my car is a slug, but we're working at it! lol

It's more than just horsepower. Without the right headers, converter, ignition, and carb. Also the car has to leave the starting line hard. Two cars with the same horsepower, will run different times. It's the whole combo and how good one is at making it run. But like has been said on here, bring your wallet.

Hey Dave, this is why I said 20k lol. I'll stick with my 350/268 though Jamie too many rocket ships in G and H! Think I will hang out in I and J.

Re: What would it take?
 
Cooter, looking at Div 2 qualifying history on DRC, You can go to J and be clear and free and I may end up in G. Most of the cars I am avoiding stay in H . There was average around 5 I cars most being 80 under camaros, adkinson is in I and slowest I car was 79 under at most races.

Dave Ribeiro 02-03-2015 05:49 PM

Re: What would it take?
 
Cooter,

Smart move to stay in J & I with a 350 / 268 combo ... Yes, G & H are very Fast classes, which means more bucks !!! Cooter, have you had the car out testing yet ??? Good Luck , see you @ VMP in March .....( CCRA )

Re: What would it take?
 
Dave, I actually was able to make Darlington race at the end of last year and CCRA race at Dinwiddie, and Steven Rowe drove it at Reynolds lodrs race last year. Got some good data to go off and it's promising but needs a little work. I was looking forward to the division 2 races until I saw the schedule, it's likely that I only go to Dinwiddie and Rockingham for the start of the season.

keep in mind that most of the online calcs use factors for a standard geared vehicle.
case in point : check the MPH vs ET on a typical street combo , say for instance 13..XX ET at 105 MPH.. now look at the ET vs MPH in a science car.. very similar MPh but a way lower ET.perhaps a .6 0r .7 lower ET.
To best work the numbers within a small window, just pick up a 10 buck calc that does CUBE root..
Now try the mph X 426.. now take the result and multiply it times itself two times i.e. 426x 125mph = 532 ..so .532x.532x.532= car weight as raced, say 3310 pounds...= 499.78 HP,. so plug that number(500HP) in the Wallace ... . all still following? that is common hot rod math.. now the calcs are set up with a factor for ET of around 5.8 ( usually 5.825) but a well setup drag car is closer to a 5.6 factor...So what you see are numbers maybe like an ET of 10.9X at about 124 mph... so instead of using 5.8ish use 5.6 like: 3310/ 500 = 6.62 Lbs /HP..now find the cube root.. 6.62 cubed = 1.877670269 x a factor of 5.825= 10.93 ET so try a factor of 5.6 for a well scienced car and you get 10.51. That should be about the ideal ET. case in point a previous record GSA car ran 125 at 10.58 .. pretty close for a 9.99 (plus tax where applicable) calc.. So you can back track and if you know the MPH and weight you can see who is making HP, got car hooking and who is full of./..A 3500 pound Nova that the owner says makes 600 hp and runs 118 mph is NOT making 600 hp.. closer to 450.. Yeah, you can run a 11.40 @ 125.. or a 10.50 .. MPH takes HP.. ET takes a complete package... Hope that helps and I was not too obtuse..
