Re: All 305 Engines Horsepower
 

Keith,
How familiar are you with Mopar hood scoops? If you are you wouldn't disagree with me. Fresh air introduced to the engine compartment is not always a bad thing.

Re: All 305 Engines Horsepower
 

I also owned a SS 255hp 85 Camaro. Bought it from Brian Tilburg, raced it, sold it. Last year Wally Clark tried unsuccessfully to flip car over backwards at Lebanon points meet. It had the plastic piece on.

Re: All 305 Engines Horsepower
 

That car is not fast because of a few degrees cooler air under the hood. It's fast because the hard work and dedication it takes to build something that fast. Kenny craftsmanship and understanding of what it takes is the reason for the performance of that car. It has always been bad fast. This last weekend everyone got to see it for better or worse.

Re: All 305 Engines Horsepower
 

Todd,
You are so right.
I'm amazed of the power this combination makes and the 12 horsepower seems to be warranted.
Which makes me ask, why spend the time and money to protect the number?
I'm old school and thinks it's crazy. The fastest of the fast don't even let it fly at Indy.

Re: All 305 Engines Horsepower
 

Due to the overwhelming demand for small 305 cams Bullet will be closed today :)

Re: All 305 Engines Horsepower
 

I'm extremely familiar with hood scoops. I've built a few. They went really really fast!

Re: All 305 Engines Horsepower
 

The TPI air dict does not belong on any carb combo. It may help with under hood air temp in to the carb but no ram effect.
My guess is Kenny was testing or giving everyone something to look at or on his journey to making more power. ;)

Re: All 305 Engines Horsepower
 

I took Bud Pickens super stock Camaro to the first Sport Nationals at No Problem and I knew nothing about car but tech sure did. I had to borrow a drill and remove the air duct in question in this thread. Didn't question as to why I just did it. It has been on there for years until that event

Re: All 305 Engines Horsepower
 

Wesley, most likely

Re: All 305 Engines Horsepower
 

That's correct. The inlet area of the scoop is more critical than the size of the scoop. If the inlet is too big, then you need to bleed off the excess of inlet air due to the fact it will induce drag on the car and unnecessary turbulence inside the scoop that will effect the performance of the engine.

Also, a hood scoop only becomes effective after specific speeds.

Re: All 305 Engines Horsepower
 

Fully agree Billy.
What I was stating is the air cleaner assembly is not the reason why the car is fast. It goes fast because the hard work put not only on the engine, but also the car.
This particular air cleaner assembly does not have a ram air effect; it draws air from the bottom of the air cleaner. Even my son's V6, 1997 Firebird had this air cleaner assembly.

Re: All 305 Engines Horsepower
 

Like many, it goes fast because it was not factored correctly and the system that's in place to do so is not allowed to work as intended.

With the respect due fellow racers, what's wrong with factoring cars prudently commensurate with true performance capability?

Re: All 305 Engines Horsepower
 

Put in a 5 speed manual and all is well.................and fun!

Re: All 305 Engines Horsepower
 

How does NHRA know the real performance of some of the newer combo's? They don't, because they base the HP ratings from what they see and record from the racers. If a guy holds some in his back pocket it could years for that combo to be fairly rated or until another racer with that combo shows his hand.

Re: All 305 Engines Horsepower
 

It's the "holding" and protection of the combination that causes this dilemma.

In fairness and for the respect of competition, what's wrong with accurate factors based on actual performance capability? Those that aren't willing to apply the effort and invest the time won't compete favorably in any case.

Re: All 305 Engines Horsepower
 

A little interesting tidbit is that 1983 Camaro coupe is still factored at 263 HP.....

Re: All 305 Engines Horsepower
 

I thought I might make a couple of points here.
This is not meant to knock anybody .(Okay, maybe NHRA) .I've known Kenny for a long time . He helped me build a S/S Chevy II station wagon, over 40 years ago. He certainly has paid his dues, both literally and figuratively.

* Jeff Stout told you what's supposed to happen if you show up with an F.I. air inlet duct in front of a 4 bbl. carb engine. That alone is a good reason to have knowledgeable tech guys look at every car, every race.

* I always thought you supposed to take everything off of the front end of a drag car , that wasn't needed, no matter how small or light. ;-)

Re: All 305 Engines Horsepower
 

If Tech says you need the body pcs. to present your Camaro as a Z28, like hood, ground effects, spoiler, etc. and of course your min. weight is different than a plain Camaro then that air inlet should be on the car. You can't suck and blow at the same time. Hey that's 2/3's of a pun, pu

Re: All 305 Engines Horsepower
 

In a perfect NHRA tech environment, there would be proper technical inspections performed by dedicated and knowledgeable personnel with the resources necessary to enforce the rule book, and back in Glendora and the Divisional offices there would be a knowledgeable staff to closely monitor performance, factoring and technical standards.
At one time all this existed, but it will never happen again, the NHRA won't fund it because it's no longer important to them. They've made a business decision.
Just an observation, not a criticism.

Re: All 305 Engines Horsepower
 

You are right NHRA doesn't give a damn . It is all money to them :mad:

Re: All 305 Engines Horsepower
 

A carbureted Z28 would have that? Or, would it not be a Z28 without the EFI?
With, or without that plastic piece, but a carbureted version did not come with that. Could help direct air, but did not come on carbureted cars. I worked on those when they were new.

Re: All 305 Engines Horsepower
 

Anyone have an idea what NHRA's thinking is on this one? Looks like the same engine, but I have to be missing something obvious. They changed it back a day later for some reason.

Re: All 305 Engines Horsepower
 

An 85 Camaro in any body style shouldn't have been able to run "f".

Re: All 305 Engines Horsepower
 

Because a 1983 Camaro has a different front fascia than the 85/86 Camaro. It is a different car. It's a different engine as it uses a 432 intake manifold...in addition to being allowed the 055 and 053.

Re: All 305 Engines Horsepower
 

Ok. Thanks. They'll have to change the 1984 180hp back to 263 as well.

Re: All 305 Engines Horsepower
 

Thanks for the further explanation. I learned something today. I didn't realize they got that technical. Thanks again.

Re: All 305 Engines Horsepower
 

Keith, remember in Orlando Bruce gave you a hard time about not having a Berlinetta
sticker on the side of the car? I worked for Gm in the 80's no cars other than z28 and iroc had Tpi. and nhra allows it. I put a factory z28 air cleaner and hoses on my car once, it slowed it down. If any of you really think that plastic picked that car up, I have spinner hub caps to sell ya.. and once last thing. Ron and others work hard to go fast. I have been and Index runner in may life. I have worked on my car for the last 27 years. and I may live long enough to go that fast, I hope. thanks

Re: All 305 Engines Horsepower
 

I agree. Am I missing something?

Re: All 305 Engines Horsepower
 

x2

Re: All 305 Engines Horsepower
 

Not many people know about that story. It actually said Camaro 2.8 on the back bumper and he would not let me call it a Berlinetta unless I showed him something on the car that said Berlinetta. I couldn't find anything and got stuck running k/sa against Brandon Wood and Jim Parker. When I pulled into the lanes with 80 pounds of ice on my intake Jim Parker started calling me the "Ice Man". Then Woods found out what ice did to my car. When I got home and changed the front plate it said Berlinetta/ Camaro under it. Bruce always liked top tell me I was in the wrong class. Someone had to.

Re: All 305 Engines Horsepower
 

Keith, I remember that trip well, you came to staging with the hood up because there was so much ice on the engine that it wouldn't close. That's only been 15 or so years ago, 2001 if I remember correctly.

Re: All 305 Engines Horsepower
 

good times..

Re: All 305 Engines Horsepower
 

So. Did the firebirds get the horsepower also or only the Camaros?

Re: All 305 Engines Horsepower
 

Firebirds also..

Re: All 305 Engines Horsepower
 

I just looked at the 85 Firebird. 264hp.

Re: All 305 Engines Horsepower
 

There is no big cam 305 in a 1985 firebird only small cam @ 262 HP

Re: All 305 Engines Horsepower
 

My mistake.

Re: All 305 Engines Horsepower
 

86 Firebird big cam 275....RIP !!

Re: All 305 Engines Horsepower
 

190 hp big cam 305 was available in 85 TA,why it is not in the guide your guess is as good as mine. Rick

Re: All 305 Engines Horsepower
 

I wouldn't be too sure about that.It will probably look pretty good in a couple years when the small cam engine is rated higher.
