I am kicking around adding this during the summer. I dont want to run a ton of boost, low to mid 20's. Is it worth the trouble if I want to run a conservative set-up or is it more for racing and running balls out. This is 90% street car, I'm not looking to get into the elevens or anything.
Thanks guys!!
-
Are you having trouble running those levels now?
-
I run about 18lbs now, if I get above that I get knock, especially at the shifts. Just looking to get a bit more punch without the knock issues

Assuming your tune/FP and chip are correct - It depends on what a few more lbs of boost is worth to you.
I will let the others chime in now!

Thanks. I dont really have a boost number I'm shooting for, I would just like a bit more pull and not worry about getting knock. I'm pretty sure the knock I get now is false from the shift.
Only ran the track once last summer, very hot and humid and I have low profile street tires so I cant leave very well. That being said the best I could run on 92 octane was 14.5.....I was really dissapointed.
This spring I'm removing the Flowmaster exhaust and getting a Pypes cat back system. Should be an improvement. I've read Steve Woods site a million times and with a good tune, even with my "bad" street tires I should be able to get into the low 13's without alchy!
-
I may be wrong, but low 20's should be possible w/o alc, and not a huge amount of knock.
I don't claim to know a lot though.
:doh:

in most cases, 18 is pushing it on 93. Every once in awhile, some one does better. It helps to have a longer duration cam in the car to reduce cylinder pressures.
For the most part, running alky brings these cars into a new century. A single nozzle kit is the easiest to tune and I suspect 25 psi of boost will add some 70+ hp to the car which will be very noticiable.
I believe alky is the greatest advancement every made for these cars.
-
any sugestions an a particular kit to go with? Cottons razor set-up? $580 for 70 HP is cheap

Go with Razors kit you can order it direct from him alkycontrol.co m i think is the site and the boost will be more like 22-23 any you'll be happy like Steve said some can run 20 psi without it but most like me 18 was pushing it
-
Most can run more than 25, but, we always should remember that the more hp we make, the more wear we put on the engine. It does not matter how you make it, cylinder pressure is cylinder pressure and it all puts a strain on the component.
I would buy straight from Julio at alkycontrol.co m. He provides excellent support and it comes straight from the horse's mouth...so to speak :D
I have run as much as 30 psi on alky, but, I admit that I really did not mean to :D I usually set mine around 26 or so.
You don't have to, but, I would suggest getting Eric at TT to upgrade your chip to his alky version when you install the alky kit. It recurves the fueling a bit to allow the alky to take the place of gasoline so a small degree.
-
Whew! Finally the experts show up. :D
-
I may be wrong, but low 20's should be possible w/o alc, and not a huge amount of knock.

You are correct, TSMG's 87 would run 21# of boost all day long with no knock. That was the old setup with a Red's chip and a TA49.
-
Look no further than Julio for an alky kit. Get Eric to burn you a chip...or have him reburn the one you have if you're running one of his...and be completely honest with Eric on your setup...and the maximum PSI you're gonna run...as this is how he sets his 02's. With everything being equal...you should be able to run 24-25 lbs of boost with zero KR with Julios alky kit and Erics chip on their default settings. As Steve says...there's a noticeable kick in the pants moving up from 18-25 PSI.
-
I've often thought a thumbwheel setup would be ideal.
When you switch to the alky profile it also enables the controller. The low alky sensor could also switch to the other non alky profile.
comments?

Yes it's possible. There are several caviats though. First it must be known good 93 octane. I think the OP mentioned somewhere that he is using 92 (yes there's a difference).
Several other factors come into play to run 20+ on 93 only. You need to be running a chip with relatively low WOT timing (mine is 20* in 1st and 2nd, and 18 in 3rd).
I'm also running a very large front mount intercooler. My manifold temps never got over 99.8* last summer even on hard, long WOT pulls.
I run an easy, solid 21# of boost in 1st and 2nd, and 20# in 3rd.
So it can be done, just takes the right tune and parts.

Here in Wisconsin you can usually only get 91 octane and it almost always has 10% ethenol it it. Is that a factor, the ethenol blend I mean??
I was having some boost control issues before ( corrected now) and when it would get above 20LB it would knock BADLY. 18 is max for me now.
I am pretty sure I will be getting the alchy this summer.

Must be the part of WI you're in. Where I grew up(southwestern part), and visit frequently, we can still get good 93 octane (and almost everywhere has 10% E)
Our gas around here also has 10% ethanol, but doesn't seem to hurt one bit.
-
18 is very good for most....alky will change the way you look at your car :)
-
I was ASSuming you were using 93 octane.
-
you guys have me all fired up to get this installed!
Stupid question time, seeing that I'm not made of money, I know the flowmaster exhaust is less than desirable for these cars. I got the car with a brand new exhaust installed right before I got it. I was going to switch out to the Pypes system but if I'm spending 500-600 on an alchy system, will the difference in exhaust be that much. The exhaust would be my next thing after the alchy but I've read so much bad stuff about the flowmaster that I'm askin, wait till I can do both? or alky, then get the pypes?
-
no, it will not be that much different...an d, an option would be to change the mufflers only and not the rest of the exhaust....

Alky is one of the best things for the Buicks :supz:
-
Didn't Steve have a homebrew Alky system on his site?
For basic use - it a stepped controller really needed? I think most buy the pumps from Northern Tool.
-
the pumps have been reworked to survive under 100% methanol and for much higher pressures which really improves the atomization.
the drivability is better with the progressive kits because it makes it possible to avoid transitional knock without having to flood the engine at lower speeds which kills the spool

Point taken

G....do you have a specific question :)

G figured out to fast track to the Buick chicks section. 5 useless posts. :)

I couldn't agree more! I went through two SMC kits and I could never get the thing(s) dialed in right. I am in no way saying that it was the fault of the kit, but I had no luck...either I was knocking or bogging no matter where I set it. Due to how rarely the car left the garage I opted to just run a full time race/premium mix.

Got rid of those years ago. *But*, at the same time threw out the up pipe with holes in it and got a chrome one with a MAF pipe to match...those are in the trunk.

Another vote for the AlkyControl system.
I bought my setup from Julio 4 years ago, and had to call him this morning to troubleshoot a minor issue. He walked me through it as I was under the car, and got me pointed in the right direction.
It's not JUST the quality of the product (which is outstanding), it's the service. And for that Julio is second-to-none.

Found 'em.
I found the MAF in the backseat - is it good? I will be pulling the MAF translator from my other Buick for the GN though.
