Hello Again! Just another of the never ending questions about our much beloved Turbo Buicks! Some background first. PTE 52, CAS V-4, Walbro 340, hotwired,009's, Lubrant chip (23 degree's), 160 T.Stat, 3" Dynomax w/super single exhaust, and currently running 22 peak boost ( 1st and second ) and...

Good Afternoon! I am in need of some advice in regards to my rear suspension. I am running a 57,000 GN that is slightly modified ( well, nothing radical, anyway! ). Nearly everything on the car is new or massaged. Lately, it feel that the rear end of the car has way too much wasted motion, What...

Thanks for the reply. Also, I forgot to mention that at the time of the old 1/8th mile run, the car had a B & M Shift Kit. I also know that the car seemed to be running kind of rich. I just recently had the trans rebuilt at 55,000 miles and had it upgraded to a Trans Go full race shift kit with...

About the Denso 0-2...... Get one! I have only used them since the first time that I read of them on this sight. I run a 50/50 mix of 110 leaded and 93 unleaded at all times! The Denso usually last me for several months, or approx 2,000 miles! My car does not like Bosch, they maybe last a few...

Good Morning! I just would like somebody to make an educated guess guess as to my E.T. with my current combo. I do have some idea as to what it will run, as 3 years ago I was able to take it to the strip with some of the mod's, just not all. The 1/8th mile times where as follows: the 60" was...

You will think that this is stupid, but I have had my share of experience with this problem more than once. Check the plug wires, especially look at the ends at the coil pack. Lokk for rust and/ or corrosion. Also, look for rust or corrossion at the terminals on the coil pack. If any exist...

I just got your email, so sorry for the delay in a reply. Unfortunately, I have no way of helping you. I uninstalled my BstC Boost Controller last year as my performance was very inconsistent with it. I found out later that I had other issues, so if I install it again I will get back with you...

I had the same problem in the past. It was a faulty fuel pressure gauge! I replaced the entire fuel system, with the pressure gauge being last, so I know from experience! Oh well, I needed the 340 anyway!

Good Morning! I have had a few questions in the past about my transmission in the 1987 Grand National. I had the trans overhauled at 56,000 miles just looking for a harder shift. At that time, it already had a B & M shift kit, but it also had very worn 215/65-15 Eagle GT tires. It would always...

Good Morning to all! I was on my way to work today, when I saw a very nice looking convertible ahead of me on I-140 here in Knoxville. I had not seen this type of car before, so I accellerated to get closer and actually see what kind of a car it was. Well,I guess the driver must have looked in...

No Jim, I have not yet done a pressure test. I talked with a tech expert at Trans Go and he had asked what the pressures where. I did not know, but I will have the builder check it on Tuesday. The tech man seemed to thing the 3/8 bolts under the acumulator would do it. I guess that I will know...

It is actually set a little tight. remember, I am looking for the firmest possible shift. At the factory setting, it shifts better from 3-4 but looses some of crispness from 1 to 2. It is 2 clicks shorter than the factory setting. Thanks

I have just changed the tires on my GN to Remington Performance GT's on the back in 255/60-15 and on the front in 235/60-15. Both are mounted on the original wheels. I have a good amount of mods and I ran 95mph in the eighth mile at 7.99 with the 215/65-15 Eagle GT's. My 60 foot time was...

Hello! I have been having a some issues with my transmission, so I have played with my tv cable alot lately. I found that if you push in from the front, effectively shortening the cable, that I had exactly the same problem. My 1 to 2 shift improved, but I had a very noticible delay in shifting...

Good Afternoon to all! I am the one that had the post about the Trans Go HD2 shift kit. I will give a little background first. The transmission in the car was the original TH200R4. It had only 56,000 miles on it. I had a B&M Shift Kit put in at like 35,000 miles. I also had an Art Carr 2800...

Thanks for your reply! I am not sure if it is the same kit or not.If so, a problem may exist. The transmission had previously had a B&M Shift Improver kit installed. It was a few years back, but if memory is correct, that kit had some vavle body mods. It seems like the valve body was drilled in...

P.S. The GN is faster!

Good Afternoon! I will be as short as possible with this question. I just had my th200r4 rebuilt by a builder that I have used before. I was very pleased with his build up on an AOD in a Mustang race car with a Supercharger. It ran high 12's with the AOD and a 2800 stall with 4:10 gears. The...

I talked to Mike latter tat weekend and it was the wires that caused his car to perform badly at the track that day, and theheat and humidity. My assuming the wires were good on mine caused me to replace lots of parts. Can you say "spares"!

Good afternoon to all! Just a quick question. On a 1987 GN with the stock gears and oem tires and an Art Carr 2800 stall lock-up converter at approx what speed will the 3 - 4 upshift occur? I only have an 85mph speedo which is pegged long before that. The cars has ran 96 mph in the 1/8th mile...
