I finally made boost

[Anonymous]

Yeee Haaa
After almost a year i started the Falcon this afternoon I put 103 octane avgas in it set the timing at 7 deg btdc set the float level, wastegate set to 7 psi and off up the road......
turbo spooling up nicely lots of noise
I went gently on her as it has only 3 feet of 4 inch exhaust and its hard to hear the tune(exhaust comes next week)
It made around 5 psi spiked to 8 and blew the cork carb hat gasket i made so will look into something better for that
I was quite pleased with how it ran considering how little had been done to the tune Number 74 Jets and the solid float is all
There was no detonation so i guess ill advance it a little and see what happens .
Unfortunately I have urgent work to do for the next couple of days so wont get to try anything for a while
Ill let you know when i do

ugh those cork gaskets dont seem to hold so well... I ended up doubling mine and torquing the carb hat quite awhile. K&N makes rubber ones...

A friend had the same problem some years ago.Finally got desperate.
Made a gasket out of leather.Never blew out another.

I never thought about a leather one Ive been trying to get a rubber one from K&N but my local supplier is useless I am going to try to glue the gasket to the carb and see what happens as it didnt split the gasket just pushed it out ...

How about going to your local plumber, and buy a nice rubber gasket?

you can get rubber mat and cut to shape, you should be able to find variying thicknesses at your local homelowesmenardsmart

What about a Carb bonnet with an Oring groove.

We use them to seal thousands of PSI at work, so it should be able to take 10 or 20

ummm I believe extreme velocity hats have o-ring grooves in some of them... hmmm I wonder how hard it would be to do something like that...

 

[Bort62]

Not.

take a carb bonnet with at least 1/8" thickness at the flange and drop it on a mill and cut a groove in it.

I was just given a type of urethane from a coachbuilder friend of mine who reckons it sticks like shit to a blanket so ill try that out then if that doesnt work ill try the rubber route My hat doesnt have enough wall thickness to put an oring into , its just an upside down sugar bowl!!!

i put the urethane on the carb side of the cork gasket only and its holding well,Ive adjusted the wastegate to allow 10 psi but im only getting to 5 spi on the gaugeIll have a check around for any leaks on the pressure side
My biggest problem so far is cooling I have the intercooler mounted directly in front of the radiator which is a good cond standrd 3 core 6 cyl rad and I have mounted a 14 inch eletric fan on the inside If i sit and idle it slowly gets gotter and hotter It hasnt gotten over 110 as ive switched off before hand I have connected the fan to run full time to see if that helps but it doesnt Out on the open road its fine What radiators are others the rest of you running ???

 

[fast64ranchero]

when it comes to overheating, the standard is, if it heats at idle you fan is to small, placed to far away from rad. or wrong combo of pullies slowing down the fan and water pump,
If it heat at cruizing speed, your rad. is to small or plugged,
you have an elect fan, so that is where I would start, go bigger or swap back to mech. fan... just my 2 cents worth.... Walt

Its got about 10-15 mm between fan and rad ill try closing it up

 

[woodbutcher]

Make sure that your lower radiator is`nt collapsing under suction.Even if it is new,it could be defective.

I am running a large alloy radaitor from summit racing. crossflow design with a pretty large fluid capacity (good siezed tanks on it) I don't even run a fan. it will stay cool in 95F weather as long as I am doing 20-25mph. I live in a rural area so even if I go in town and drive around for a bit I am fine. only got it HOT maybe 4 times in the last 5 years (all from stopped traffic on the interstate in summer weather)
