About $20.00...  and about 2000 RPM??? |
That is absolutely awesome!!
And we hear about the "What ifs" quite a bit when we start with this same discussion. "What if the Ken Black team had two weeks to build a mountain motor team and went IHRA racing. How much quicker would they be than the rest of the IHRA cars?" I get so sick of this type of talk. If you thing anyone, (and I mean anyone), can jump into this and can jump ahead of Kasse, Sonny, Miller, Fulton and the like, I believe you have another thing coming. These guys are not as out-back hillbilly as many are thinking. They know their stuff. It would take the Warrens of the world some serious time and some serious testing to be toward the top of that pack.

And there's diminishing returns as power increases. PM's are running 3 tenths better than IHRA PS and most of the IHRA AFC are appx 2 tenths quicker than PMs....SO the 4 tenths (give or take) the IHRA cars have on the NHRA versions indicate a considerable power increase.
The engine guy fron RM explained a lot about this subject but those posts went bye bye after the transition of the site.

Re: What's the diff between NHRA and IHRA Pro Stock cars?
Darin knows his stuff and really explains things well. He was a great asset to the Mater, but have not heard from him in a while.
But suffice it to say, that the IHRA stuff is no puppy. It has the highest piston speed of any race engine on this planet. When you get to those items, you get into some real problems with flame front travel, time close to TDC, and the valve size for the air needed to run in optimum performance for that cubic inch. There are physics in play that the NHRA guys do not deal with. The IHRA engines are intense!

My apologies for not getting Darin's name. I guess my grand kids are right, I am getting old!

Case in point; NHRA PS, touted @ 1500HP, NHRA TF, 8000 hp.
So, that 6500 HP gets you 2 full seconds in a slightly lighter car with a huge aerodynamic and engineering advantage.
A some folks assume if you throw 250 ci into a NHRA PS engine and test a few weeks, you'll rule the roost.
Man I wish I could retrieve that old thread.

I love the sound of those things coming off the line, they sound absolutely wicked!

Right. The money required seems to exponentially go up as the increases are achieved.
I really miss the days when the top runners would run IHRA and NHRA. I guess they now need to be 100% focused on one instead of 50/50.
