I'm just whining before I go out to drain the GTII gas tank. It's been five years since I drove it. Next time I build a tank it will have a drain. I run two large fuel filters, one before the electric fuel pump and another before the carbs, but bad gas is just BAD - moisture is the major bummer, as is low octane. QUESTION - would you recommend an additive to the new tank to clean the carbs?  All cleaned up after the fire. Not bad, eh? |

To clean the carbs....Seafoam. That's the stuff that you spray into the carb while the engine is running, right? We used to use Bardahl for that, and in a pinch we would use diesel fuel. Smoked up the whole neighborhood. |

Hey MJ that looks like the cat's meow! Let's see some pix of the rest of it! Please! There isn't much more of the engine to show. It's all inside. All aluminum cylinders, squshie pistons, big heads, h-beam rods, split cam, roller rockers, 2165cc, 10.5:1 compression, full-flow oil system, twin oil coolers, external filter, 44mm webers... all that stuff. To tell the truth, it makes me sick to recall all the money I've put in there. |

JSP - I will take it upon your word. You have built the most amazing cars.
Thanks for the advice.

if you use sea foam (great stuff ) use it outside on a windy day +wind blowing away from your house+ this is from experience . i used it at work last month and still get flack about it . couldn't see anything .fire alarms, firemen etc. you can use a vacum port to suck it into carbs

Sucking it into the vacuum port is designed to clean the valves and top of the pistons. It does create a ton of smoke. If your looking to clean your carbs you add it to your gas tank. If your looking to clean your valvetrain (ie: upper part of valves, rockers, pushrods, etc) you add it to your oil.
MJ...if your just trying to de-gunk your carbs then add it to your tank.

Hey MJ My engine is the exact same color .. Pretty cool looking .....I like the dual carb set up and have been thinking about doing that to mine .. Is there any problems with the fit , and Did you have to cut the side panels at all? currently I have a 2bbl could you tell me what size your carbs are?
Would like to see some pics of your whole car.
thanks ,
Superdave

Would like to see some pics of your whole car. thanks , Superdave My GTII was originally an electric version and the walls on each side of the engine are much farther apart than others I have seen, so you would have to measure yours. I can measure mine today and post the dimensions later. I've seen three different configurations, so you would have to check yours. It is very handy since I can install the engine with the carbs already mounted (40mm Webers). I would not recommend these carbs for a stock engine because they are just simply too much and manifold vacuum would be far too low to perform at anything less than near wide-full-open. However, dual Kadrons over a stock engine will definitely increase performance, but be careful. The stock carb acts like a rev limiter, and the Kadrons will let you wind it past redline quickly. I have Kadrons on a 1776cc Bug. I can shoot a picture of that setup, too. |

Wow! Thanks for that. I lost those pictures!
It's different today. No rear spoiler, all white interior, and new chrome wheels.

Thanks so much, minax! You are the man!
Today the generator/fan belt snapped, but I was close to an auto parts place. The guy looked at it and said, "We got that one for $8, and a good one for $14." Duh. I got the good one.
mrbigh: Never had any of the electrics. It was an empty bay when I got it. However, the electrics technology has improved so much that I believe you would be better off with new parts.

Hey MJ,
Really like your GT2.
You mentioned twin oil coolers and I noticed from the pics, that you made a rear apron in the engine compartment. Was all of this to deal with overheating?
I recently bought the Gene Berg book of tech articles GB801 and it got me thinking about how my engine seems to run hot even though it is stock.

Hey MJ, Really like your GT2. You mentioned twin oil coolers and I noticed from the pics, that you made a rear apron in the engine compartment. Was all of this to deal with overheating? I recently bought the Gene Berg book of tech articles GB801 and it got me thinking about how my engine seems to run hot even though it is stock. Tony O. The second cooler is a Setrab brand with an electric fan on a thermostat and it is located forward of the engine in a cool, high-flow area. It truly helps. The apron serves the same purpose as it does on a stock VW - to isolate the upper engine area from heat and to keep the cooling air flow going down and away otherwise there would be major turbulence that inhibits cooling. The GT-II's engine lid has a functional scoop - if you cut it properly. If you run in the rain, air comes into the scoop, swirls to the outside of the inner scoop so that the water separates from the air, then the water drains out the lower bottom of the lid to the outside It is a remarkable bit of engineering. The pipes (4 into 1 ceramic coated) are also fiberglass wrapped to keep the radiant heat away from the heads and cylinders. It all works so well that I can put my hand on the headers after a hard run. Note that with wrapped pipes the heat stays in the pipe until the end of the wrapping so that it's VERY HOT where the wrapping ends but that's where the twin quiet packs start and they are very good at dissipating heat due to their size/area. I am fond of repeating this - the exhaust temperature is very high near the ports - high enough that radiant heat (infra red radiation) is a serious issue for the first four inches. 4:1 pipes bring the exhaust pipe close to the heads. Shielding that area or wrapping the pipes is important because air flow cannot defeat radiant heat any more than you can blow aside the beam of a flashlight. Overall, this engine runs very cool, cooler than stock although it has 10:2-1 compression and is 2165cc. (The Nickle-Sil cylinders help a lot, too.) |
