IHADAV8.com - Turbo Buick Tech, and Nonsense

My friend, Steve Yaklin, of Max Effort fame, recently bought a 2009 Challenger SRT8 that someone had poured a lot of money into for ported heads, big cam, programmer, etc. It ran really well, but it was not a 426 (was a 6.1) and it did not run like his Buicks.
He had always wanted a 426 in the old days and he decided he wanted one for this car. Only problem was that he needed more money so he finally put his Black GN up for sale to pay for all the stuff he would need to get a 426 and keep the drive train together.
The old timers will remember that he was famous for his development of alky systems on his white GN that made the magazines a few years ago. He had alky on the black car as well and it had gone tens but had not been driven much in the last few years.
The black car was girdled, had shim head gaskets for higher compression, stock cam, and a ME tw chip with 18 degs of timing. I think the turbo was an old 63E.
With much reluctance he put it up for sale and some guys from out of state bought it and hauled it off after a few lectures and instructions on taking it easy and learning how to drive it. They knew nothing about Buicks.
They, of course, went straight to the track and ran a 14.10. They called him and asked what to do...start leaning it down with the thumbwheel. Next run was in the 12's, the next was in the 11's. A couple of days ago, they went 10.58 after putting 28" tires on it.
All the above is on premium gasoline, homemade alky system, 18 degs of timing in a ME thumbwheel chip, stock cam, ported heads shifting at 5200 rpm with the car in 4th gear.
The TT SD chip is the successor to the ME. Not as easy to dial the fuel up and down as the ME but the other features are quicker to change and no tw required.
There is a lesson in there somewhere.
Some pay a ton of money for a bunch of parts and don't run as well. Nothing beats combination and understanding how to set the car up.
At any rate, here is a picture of his new Arrington 426 short block/engine which was installed this week. Wish I had one!
-
Thats a nice looking motor! A 426 eh? And he put this in the the new SRT8?
-
he had the 6.1 pulled out of the 2009 and used the big heads off the 6.1 on the new 426 short block
-
My question is will it break the glass windows in some houses like the old one could?
Very nice.

This one is pretty sedate, I understand. Maybe he just needs to run it open header

Dual 3 1/2 inch out the back will work nice with some high flow mufflers. lol
But I guess it depends on the cam heads etc that are on the new ones.
I have not played with the new ones yet. That is why I asked.

It looks good but when you said 426 Hemi i had dreams of a Keith Black, huge double pumpers, loud azz kind of motor! :rock:

I don't recall if the car has magnaflow or Flodisasters on it...The cam that was in it is actually a bit larger than the new cam that Arrington installed. I think the new one is something like 234 degs in duration. the old one looked to me as if it would probably make peak hp beyond the rpm potential of the car.....with the extra cubic inches, I suspect this one will be around 6500 rpm at the peak...
The gear ratios in the automatic have a big jump between third and fourth as I recall and it is tricky to get the after shift rpm to be close to the torque peak. Again, I suspect the extra cubes will make that problem diminish

I can tell you are from a prior generation than most! Fuel injection is ever so nice for a driver these days.
The problem with the Challengers is that they weigh over 4000 lbs in spite of the light weight engine, etc.

Looks like a stock hemi with a 426 sticker on it. Boooooring.
Late model engines are boring to look at in general... but, damn do they work well.
And if he really wanted to go fast he should have got a Drag Pak car.

he wanted transportation that would go fast...
Me, I would have not put 426 anywhere on it
-
Steve's an awesome guy - Mr. Wood you need to get him to log in over here.
Wonder what the 426 will run.
-
Yes, he is. One of the nicest guys I have ever known...and he has an idea every five minutes and not just about cars. Impossible to tell him he cannot do something. He can put a turbo and alky on just about anything. Spraying alky on his snowmobile and turning the boost up...
I don't know what it will run. It still has 3.06 gears in the back but the extra liter of engine seems to have really kicked up the torque. He has bought some no hop suspension stuff but apparently you have to completely disassemble the rear end to install it so he has not got into that. Transmission and axles are probably right at the limit now.
I think it will be in the elevens if he can hook it. Think the damn thing weighs about 4200 lbs and that does not help. For some reason he does not want turbos or a blower. He ordered a Snow III kit for alky to install in case he has a little detonation. Arrington put 11-1 pistons in it
-
The LS2 in our TBSS comes stock with 10.9:1 compression and weighs more than a LX-chassis car. He just has to tune for knock and maximum brake torque (both fuel and spark) to overcome the short comings of being heavy. Not hard to do it just takes some time, and acceptance that running 30*+ of timing across the board went out of style with the original 426 HEMI.
-
He know what he has to do...what he is trying to do is to run as much timing as possible without detonation...h ence the alky :)

I get that, and I understand that he is a smart man... I just find it odd to use alcohol injection on a N/A motor when the gains will be minimal at best assuming good fuel and proper timing/enrichment is used.
-
20-30 hp is about the best one can hope for, but, one can bump the timing further and assure ambient conditions don't bite.
I ran alky on a bbc back in the '80s with good success altho it was crude by todays standards. Now you can tie it to DC and cool down the charge air quite a bit
Not everyone walks the beaten path
-
I'm surprised more guys don't spray alky for NA applications especially with higher compression motors and modern pump gas.
Been trying to talk a buddy into trying it on his bottle fed 383 stroker.
-
It's not all that cost efficient unless you are trying to run close to the edge in my opinion. It works, but you don't gain a 100 hp
On the other hand, look at what guys spend for a set of headers to get 9 hp...so maybe it is cost efficient but is simply not well understood by the na guys
-

Don't I know it.
I'd say he'd love an E85 conversion to realize the full potential of that 426. Again that has its limitations, and everything has its compromises.
-
Sounds like that thing needs gears and a cam in the 250-260 duration range :rock:
-
rods and valve train won't handle that rpm
At least one guy running 10.8 on 3.06's and he apparently tried them all shifting at 6800
-
Really.....wow .
Makes me like my LS even more. Now with some luck the clutch that they send me will shift at WOT. Waiting for the flywheel to be machined again and then it need a few hundred miles break in on it :013:
I'd like to see a mid/high 10 @ 128-130mph yet this year.
-
I would think you would like something that you could cruise all day in and still go fast in the quarter?
The automatics have some pretty stiff gear ratios and add a good converter to that and you don't need all that gear like a stick
-
Double over drive fixes the cruise issue.....75 mph at 1800rpm is fine with me.
Some day it'll get a 4l80e - but not right now.
-
I am waiting on getting a 6L80E or 90E conversion for Natasha's Camaro... what an amazing piece of engineering! Someone just needs to create a stand-alone control box or an OS conversion for HPTuners.
Either that or we'll just dump the Camaro and get a CTS-V next year.

A REAL HEMI.........5 30" of it! :icon_madu:

Nice Chuck yours?
Whats under the filters size wise?

Probably some throttle bodies - it's fuel injected.

Yes; I was curious as to the size and the distance, diameter etc was. Hence could figure out some of the data.
