Cruz tests new NHRA Tech Dept Combo

[Z28LT1]

OK guys and gals, help me understand this. They, the NHRA, are trying to slow the fuel cars down, correct. Now wouldn't changing the gearing in the rear ends of these monsters slow these cars down? If you were to put a lower gear ratio in them, like maybe a 238 Vs a 411, wouldn't that lower gearing put more drag on the motor, making it slower off the line and causing the RPMs of the motor to rise slower, so by the time the car got to the finish line the RPMs would still be down, since there is more drag on the motor do to the lower gearing?? Or am I way off on this???

Hey Jerry, Nitro motors like a lot of load; dont they? A TF car doesn't need all of that wing to keep the car on the ground, right? Isnt the purpose of those big triple element wings for the added load on the motor? A/Fuel and Alky dragsters being an example of two cars running simular ET's and simular speeds with th Alky guys running a smaller single element wing. if that is correct, then would the above have the opisite affect then what Richard is suggesting?

Richard, I'm totally not flaming you, just asking a guy who'd know based on what I thought at one time to be true. the question is for both of us.

BTW Jerry, it was good seeing you again out at Stanke's shop a few weeks back.

***EDIT*** Sorry, I guess I should read the whole thread before posting. Thanls for answering the question I hadn't asked yet Jerry! HAHA!!!

Why is Cruz testing it and not asking JFR ????? thats partiality to the ped brothers !!! Why isn't anyone whining about that !!!

Don't. Please just don't.

Don't. Please just don't.

HAHA

Hey, Martini...

you wanna tell William nitro's been running a spec motor for the last 40 years, or should I?

Haha when I say spec I was meaning a motor where you could only run one type of blower one type of piston one type of cam stuff like that where everyones engine is exactly the same and you cant change anything . I wouldnt call the motors they run now spec I would mearly call them regulated because they can still do stuff .

 

[Mooseman]

plus how have they been running a spec motor for 40 years , im a huge hemi fan but when they first started running these hemi's nobody told them they had to use that engine it just worked . Other engines were tried many came and went but the hemi worked . It was only when they banned all the overhead cam multi valve engines engines that the hemi was made the only choice , and hey even chrysler had an overhead cam multi valve hemi in their plan back in the day though it was never put into production .

I'm not sure this is slow enough for nhra. Don't forget gang, this was a first test. By only one team. You know once the other teams get their hands on it, they'll be goin 4.2's and 4 teens in no time.

 

[Mooseman]

The one thing that really scares me is that the nhra is an organisation that once banned nitro . Now sure that was along time ago with different management but still .

...BTW Jerry, it was good seeing you again...
...Thanks for answering the question I hadn't asked yet...

Crazy Minnesodah people ,burning Nitro at 35 degrees outside... it maybe a small blower but I can burn 95% for sound ...
They turn 8200 rpm now , that's enough for 4.500 stroke ... 300+ with a 3.20 gear will be less rpm , and easier on the tires...
Save money, don't spend more to wipe out more budget burners...

One Mag , Same good parts, 300+ mph... Free the Nitro ... run 95% ... Free the Nitro ...
All together now ... call NHRA to ...Free the Nitro ... run 95% ... Free the Nitro...

Yer right sir, I believe it was 5 or six years. Hmmm, I'm thinkin from 1958 thru 1962?? Not sure, but I'm close.

Wasn't the first test (Danny Wilk had one, and I think there was one before that). It HAS BEEN the most sucessful test from all reports. They are going slower- it's where they want to be going. You're probably right tho, Zappy- they probably need to knock another .2 out of this set-up to keep the Brain Trust occupied for a while...

Wilkersons was a smaller engine, different rear end, and several other things. Looks like Cruz used most of the same good old stuff they already had, so I'd call it a first test of that version.


Jerry-"Free the nitro!" That is funny.

I think Wilk tested the 400in version. I may be wrong?? This was the first 500in test I know of. What I'm saying is, if a first test got 4.37.....you give a bunch of crew chiefs 30 days and they'll have this combo in the teens.

I just don't want to see mid-season rule changes. What ever combo they (nhra) pick, I hope they stick with it the full season.

I think that's why they are calling these things "TESTS"... Think they might be looking for the right combination of things across the board?

Whatever we get as far as a "Spec" package will probably not have been tested as a whole by one particular team, if it ever gets tested as an entire package at all. I will bet the final package will be a combo of several bits of all the successful data gleaned from all the tests, just to keep it fair for all the teams (and so the keyboard guys don't whine about one team having a head start over everyone else...)


Jerry: I'm an XL- where do i send the check?
