captain jack has the BEST friends :)

Re: U/SA
 

So the discussion of the 230 led me to a question: Let's assume that an engine with a carburetor that flows twice the cfm of the cubic inches is "well fed". Are there any 4 or 6 cylinder engines that come close to that?

Re: U/SA
 

As far as inline engines, not sure. AMC 6 cylinders had fairly big 2 barrels. I know some Chevy truck inline 6 engines had 2 barrels later on, but they aren't in the guide. There seems to be a decent number of "well fed" v6 combos out there. Maybe not all 2cfm/CID, but there is an 86 Chevy truck 262 v6 with a quadrajet in the guide.

Re: U/SA
 

My Super 6 with the Carter 2 barrel is rated at 280 CFM. With the Holley 2 barrel is rated at 250 CFM.

Re: U/SA
 

My 267 V8 is fed by a dualjet flowing only 287 cfm !

Re: U/SA
 

Yes.
1967 Pontiac 230 "Cammer" ...750 Qjet !
Problem is it's gross rated at 215 hp..Just about the same as some power pack 283'S

Re: U/SA
 

Mark, you have been at this game a long time brother. It really just boils down to the age old engineering question of "what is the best air pump actually listed in the classification guide" doesn't it?

If I just had a taste or small percentage of your knowledge back in 93' I would have saved myself a lot of heartache, money and effort and studied that question gone out and bought what I needed.

Instead of taking what I had, taking it bone Stock low mileage w/the A/C Compressor on it, running a 10th under first pass, won a few bracket races with it and saying it has to be pretty easy to go a lot more under if I take it slow and find out what works to make it go faster legally.

That did work for a while as I reached to just over 7-10ths under, then the wheels came off and hit a wall, took it to San Dimas, they classified it as 110HP (instead of 99, and FF/SA orig. Class, but it weighed in well over 25.00 per. So GF/SA it was at 2,755 (raced it at 2,763).
lbs.

Based on today's classification #'s, even that was wrong.

Fast forward to Englishtown, NJ Nat. Event May 1995, and a visit by the Nat. Tech Director (we are not going to tear you down....yet, unless you want to go through a mock 1, since we know for a fact you are almost pure factory (But Bernie please report to the Barn!), so a discussion begins, my question was, why on my meager 99 HP slow sled did someone just pluck out of thin air an 11HP hit to apply to my combo, and his answer was "that does not happen, but let me go look at it!"

30 mins later he came back and said, hmmm, all the data history we have on your sp

Re: U/SA
 

Specific combo, are all your prior passes, nobody but you has ever attempted to race that particular 84' Daytona, single point injection (non-Turbo), 2.2L/135 Ci combo, buy that should tell you something and we can't figure out why, as only 3 passes are close to being reasonably fast, still nowhere near fast enough for an HP factoring hit.

We cannot cure it today, but a letter requesting a review is in order, so lets go look at all the part numbers, so when you request it we have the data correct..

We did, the intake was a superceded mid year change, not on their sheet, a phone call cured that in 5 mins. And the Class Wally was mine that day.

December 1995 sent the letter in, Feb. 6th, 1996 the answer was congrats reduction to 99HP, and the intake number was added.

Sadly, I could no longer afford to do the diet and improves at that point in life anymore. (I spent it all racing carrying 25.00 lbs. X 11=275 lbs too heavy a car at 110HP factored).

Fast forward 25 yrs., I dieted that car down 275 lbs. Legally to 2,455 lbs (Guide says advertised shipping wt is 2,444 (within 10 lbs.), and lo and behold it has been hit again w/6 HP on June 6, 2003.

Best I can tell, though I have asked, not rec. an answer yet (as I know no other fool has still raced that exact combo but me so far), was the hit had to have been triggered by the combining of GF/S, GF/SA, and later FF/S, and FF/SA into EF/S. (I am assuming that, as it was about the time of the culling and FWD class combining decision). Or, it was some engine family decision based dead, but all speculation at this point.

Now classed orig. in DF/S (car cannot legally be lightened to top or lightest in that class, so EF/S it is, and 6HP hit, causes it to Min. Wt (Same 25.00 lbs/HP, 2,795 car and driver, same Index 17.45), I'll race it there for now, and let it gather some real data, then request another review I guess, as it has to be the heaviest EF/S car today I suspect.

Oh, that is 32 lbs. Heavier, than last raced in 1997. (Which is about how much weight I have personally lost just getting older). I have written proof (and a large parts pile, the car never weighed or was ever advertised to weigh less than 2,529 lbs., with a curb wt. of 2,590 (5 speed man. Or Auto- both from the Orig. Dealer Brochure/other sources). Even the TurboZ was 2,600 plus Advertised shipping wt.
So, the secret sauce seems to be, what mfg. provided the best un-truth on the plus wt, and what mfg. added the best to make their model the most efficient air pump?

Re: U/SA
 

I realize this is not all about me, I am older, I am supposed to be wiser, and still doing dumb things...But, this time I am here to learn and have a lot more fun, and time is getting much shorter, so I am attempting to understand as much as I can. (At least it is no longer rotting up against the wall of the garage with years of AZ dust on it!)

90 percent of the time it is just another bracket race (with the index being the top), but the other 10 percent, is the smart decision a person needs to start with I guess, an efficient combo that runs well under.

Re: U/SA
 

Are you guys serious or just home eating gummies ???? If it is not an NHRA race (something like Tyler’s 10,000 race ) would you I’ll only race if there’s a fing “Wally” type of guy >>>> let me know if you want added prize money products we should prolly get started sucking up 🤔😳😎
