Tuning With The Scanmaster On the Street???

[86BLACKT]

If no knock...add a little boost , also, you may want to talk to Razor about becoming an alkyholic, for some real fun!! . When I had a scanmaster, I used the retard to dictate amount of boost and the O2 to dictate fuel pressure. As stated earlier, using alky or race fuel will dictate suggested O2

 

[86BLACKT]

By the way, before I got FAST, I used TT ships and had good luck as well.

Yeah having my car in overdrive probably does hurt but it still does not pull hard.I got the stupid shifter up on the steering wheel rather then the console.I like to get a shift kit and console put in my car.One thing I did was install 3:73 Gear's.I should have kept the 3.42's.I am running a 28 Inch tire so it should put me back near the 3.50 to 3.55 area.40 horse power from the cam sensor wow.i don't even know where that is or if it needs adjustment.

I was looking to add maybe some nitrous before alky as it hits hard.I'd rather stay away from race gas and stick with 93 or 94 octane.I think aI need a TT chip badly.Car has always ran a bit rich.

 

[ReaL99]

I never saw a tan plug in my car once since i bought it about 15 years ago.The plugs when i take them out have a little carbon but not that bad and the plug looks like it came from the box.They look a little to clean.

 

[86BLACKT]

Keep dropping fuel pressure and I also had a bad O2 sensor that sent a bad signal and caused me to run fat. Alky injection will allow you to run higher boost on pump gas, I am not sure about nitrous. With my TT chips, Eric sid that his 100 octane chip was perfect for alky and 93 octane.

 

[ReaL99]

Alky is good I guess I just thought the nitrous would be easier.

 

[86BLACKT]

I think it took me 2 hours to install Razor's kit. Instructions are great and his customer service is second to none!! Alky will be cheaper, legal, and readily available. I think most just use nitrous to get out of the hole and kill the lag. I have used nitrous in NA motors, but I am hesitant in turbo motor. I might be a big ***** though!!

 

[ReaL99]

Thats why I posted I would use a 50 Nitrous jet with a 75 or a 100 fuel jet just to play it safe.

real99,your tune is way to rich that is why your 44 does not pull.at 18lbs you could probably be faster with a stocker.the 44 or 61 or 66 need more boost to make the power.my car goes 114.5 mph at 20lbs of boost at 24 lbs it goes 119+mph in the 1/4.inmo if you go to a bigger turbo keep it at 18lbs of boost with 02's in the 850 range you will have wasted your time and money.now you tune your 44 to 780's and raise the boost with proper fuel, and max the turbo out and want to go faster then go with the bigger turbo.

If you're going to use nitrous you'd better be using race gas. Nitrous and these buicks do not mix well unless you REALLY know what you're doing. On the other hand, alky can save a motor from someone who is just learning to tune. You'll have much more fun with alky than you will with nitrous. Once you install alky, you can turn the boost up to 25+ lbs get it tuned and never change the tune. With nitrous you'll have to be running race gas, you'll need to retard the timing, and lower the boost. Then when you aren't running nitrous (leave the track) you'll have to completely retune the car.

Im going to take it out tonight and back it off by 1 lb at a time to get near 780 Volts.Its hard for me to raise boost because to up Boost I would have to go under my car.I have a Racegate near the crosspipe.It originally led to a knob inside boost controller and I would just have to turn the plastic knob inside the car.Itook off a 601 Turbo to put theTE-44 on and now I can't adjust boost.Luckily I still get 18 lbs of Boost.Don't know why the change in Turbo's changed the in car boost controller

There's a guy on here that uses 91 Octane on a 75 shot all the way down.I think he eventually lost a headgasket though.I don't need that to happen to me. Nothings easy when trying to go a little faster.

With a te44 turbo, 3000 stall, alky with boost set to 24-25 lbs your car would be total blast to drive. If you hit the gas at anything under 40mph the rear tires would light up. Alky is the way to go. Set it and forget it. Drive to the track, not change a thing, rip off low 12s to high 11s and drive it home. The car would always be set on KILL, but as long as you're not into the boost, it still drives like a normal v6.

You proved my point talking about the guy lifting a head with nitrous. Alky will keep you from doing that. The difference between 18lbs of boost that you're running now and 24-25lbs that you could be running on alky is in the range of 90-110 horsepower. Why risk a 75 shot, when you can get 100 hp and be safer with alky. With alky you could easily be pushing 400+ hp and 500+ torque to the rear wheels.

This is on Race gas

 

[86BLACKT]

93 and alky!!!!

 

[SS_Sean]

This would indicate a lean condition, not a rich condition.

[BLACK6PACK]

Yep, 93 and alky.

I don't have race ported heads or a front mount and on about 23 lbs of boost, 93 octane with alky, and almost no tuning I pulled 405 hp and 545 tq to the rear wheels.

Without drag radials anything under 45 mph and the car wanted to swap ends. I bought Nittos DRs just to keep the car pointing forward while driving on the street. The nittos still scream for mercy, but they don't go up in smoke like the regular street tires did. Can't tell you how many times I hit it from a roll and would be white knuckling it and taking up 2 lanes trying to go strait.

 

[BLACK6PACK]

Do a search in the alky forum for "grumpy". His daughter is running a 67 turbo and supporting mods. On alky and 93 octane she ran a high 9 second 1/4 mile at the track, changed to street tires, didn't change anything else and then drove 2 hours to their cabin for a relaxing weekend. Not too many 9 second cars that can do that and still knock down 24 mpg. Granted he has some magic voodoo tuning skills, but its possible.

The reason I lost my HG is very complicated, not really the fault of the n20. 1st off my motor has had this horrible ticking sound that to me sounds like a cam lobe going flat (#3). I believe my exhaust valve isn't opening as much as it should, and it's creating problems. For instance, this motor knocked BAD when I got it stock, like 12 degrees kr and I was only making 14 psi on the stock turbo....

I had been trying to blow this 3.8 up for a while too, I am ready to get on the ball with my 4.1, and the GN is not my daily driver.

Another HUGE reason that I blew was that it wasn't a track pass where I sprayed to 115 or so. I was street racing a 6 speed LS1 and he told me that he heard it go at 140 mph

Like I say, you gotta be crazy to hurt one of these with a small shot of nitrous. I guess I am just crazier than most :wink:
