GN1 R or TA aluminum ported head flow numbers

[SLIC V6]

No need to apologize Jerry,

Thank You Mike!

I love your car and what you have done with it! I also highly respect you.
I'm not here to make any waves, just to learn and share information!

ENJOY!!!

Thanks Grass Doctor, you are 100% correct.
I should have explained that better.
To add a bit:

At the track you can usually tell serious Street Racing guys or heavy hitters when they show up with N/T on their windows.
No Time cars will make their run down the track and the scoreboards will not show their time/speed.
The Timeslip Booth Workers will usually cut the Timeslip down the center so that the car that raced the N/T car will not see their opponents times.

Street Racers and some of the quick non-bracket race guys will do this so they can Test and Tune and NOT let out their numbers for the competition or others to pass around.

I hope that this helps!
ENJOY!!!

or they are to embarrassed...to let itbee known ....thats how my NT car is ....all show and no go....

Me... 25 psi and I barely cracked 11’s

well...I look at it like this.....anyone can make a fast car....but what you cant make ...is a mint ,low mile mostly original cream puff ....survivor!!....LOL...guys been running in the 10's since the 90's with no tech...just sayin

My car runs alright........

I have Mike's flow sheet for my TA heads around here somewhere. I'll see if I can find it, if that's what this thread is still about........

 

[dank GN]

Well I flowed my TA SE heads . I ported them and my buddy’s pops let me use his flow bench and they ended up being around 255ish on the intake and 205ish on the exhaust. And from what Information I have gathered that’s just about the most you can pull from them so I was pretty happy . I also flowed a set of stage heads and a Indy square port head . I know I have the information on them somewhere I’ll try and see if I can find it and post it up

I have Chris Lyons old ported TA SE aluminum heads on my car that came off of his 8.20 TSO car. I had them reworked by Dan at DLS when he built my Staged motor. Never did get them flow tested. I should send them out now that my motor is apart and get that info.

Those are really good numbers. At what lift were those numbers achieved at?

 

[Mr.Spool]

Could someone build a 7 second Turbo Buick 109 block car with no other rules applied?
Perhaps utilizing block fill? Special machining, maybe adding cross bolt billet mains?
Any crank, rods, pistons, cams, heads available?
Feather weight, sparse interior, sparse engine bay, lightened frame.
Suspension, Instant Center and weight geometry purposefully built.
Any tire/rear diff/trans combination.
Any combination of Power Adders. (Twin Turbos, Nitrous, Blower, alternative fuels?)
Limited Engine cooling required. (Maybe it could run the full 1/4 mile and be able to idle back to the trailer.)
Could it be built?

it sure can,once you take away class restrictions and purpose build the car itself you would be amazed how fast you can really run.

 

[Mr.Spool]

Hey guys, once again I am sorry for causing this mess.
Mr. Spool has not made any claims to what his car runs. He has a NT car that runs in a different world than most of us.

Mr. Spool, I apologize for dragging you into this.

im totally fine with it.you have the right to speculate and ask questions.

 

[Mr.Spool]

exactly!

from what i understand more can be had.

Actually Mike I never ran those heads. Ironically I just came across the flow sheet for those heads the other day and I will see if I can find it again. Intake was in the 270s I believe.

The GN1R heads I ran on my TSO car and went fast with were an experimental head Tom never released that had a raised exh runner much like the one on the GN1R head I posted a pic of below. Those heads flowed 268 on intake 220 exh and when I took them off the motor last they were cracked in so many places they were junk pieces of alum. I did commission Tom to build me the absolute BEST production style head he could and I finally got them in 2010 and are the heads in the pics I posted below. These heads were on my car when I sold it and have never been run. I have the motor out to re-seal it and check the valve job springs and I am going to actually flow a port which I never did. Tom told me 289 on the intake on his bench but I never got a flow sheet.

The best head I ever personally flowed was a TA head that was done by Dan at DLS. It hit 300 on the intake at .600 lift. I had those heads on the motor I built for my drag radial car I ended up parting out in 2016. I sold the roller to Tommy and the motor went to Manny Eckert who unfortunately passed away, I am now getting that motor back from his son this weekend and will again have those heads in my possession.

So who would like to see a flow bench test and pics of two of the baddest production style heads ever built lol?

What causes the cracks to form & where do they occur? Any pics?

Please.

That's really high numbers
Tom Robison has a set of ta heads that he ported himself and went 7s.
Not sure what they flowed though.
The ta head castings seems alot better and dont crack like the champions do when someone starts making the kind of power to utilize/benefit from flow numbers that both heads can flow.
For most they will never see cracking.
Nice heads!

Also if you dont need that head
I have something here to utilize it if you want to part lol

More like where didn't they crack lol! What caused it, I would say insane cyl pressure making 1400hp lol!

You have to remember this was in 2009 with the older design GN1 castings and they ALL cracked at that power level. I never ran a Champion head back then that didnt crack. Funny thing was we would get them to stop leaking with seal tabs and whenever they would start leaking again we just threw in more seal tabs lol. By the end of 2009 I folded the Crower rods in that motor at Atco on a 174mph pass. When I tore the motor down the heads were cracked on the outside by the plugs and inside by the rocker stands they were a real mess. They simply were not made to hold up to what we were doing with them.

The heads I posted a pic of above are the "new" castings with extra material in them which supposedly hold up a lot better than the older design did. I know Don Cruz ran this head and said he still had problems with them cracking at that power level and recently went to S2. I believe Chris Hogeland is currently running really fast with the same head on a 109 motor in 1/8 mile racing and they are holding up at 5.15's which I just saw posted. I know Tommy Robison ran the TA head which held up really well and he abused the hell out of them and ran 7.78 at 3250#. The only other guy I am aware of making that kind of power with production heads is Gary Harmon which i don't know anything about his combo other than he went 7.70's which is insanely fast. If anyone knows of anyone else I missed post it up, I heard Richie Balcom went pretty fast but I don't know what he ran or when.

We were really pushing the envelope and doing things no one else had done back then in 2009. Here are a couple videos that are still lurking around on youtube. Car weighed 3450# had T4 billet wheel 47/88 with a 70mm TB 3" IC pipes full factory interior and a stock Powermaster!!

I also have some iron head porn and stories from back when I raced TSS I will be posting up for Mr Plog, lol

Happy Thanksgiving everyone!
