its been almost 2 years to the date but i cannot believe it im finally going to the track on the 26th .
have 40 lbs of nitrous and 20 gallons of c16.
Bloody hell Jim it's about time to!!!!car has taken a long time but major upgrades have been completed .
will run the same motor with a few external upgrades to the vacuum system . all new disc brakes , new dual disc tilton clutch with hydraulic clutch managment , custom irs rear suspension with almost no camber change coupled to a new taller geared 4 speed bus based gearbox with what i hope are very strong internals this time around .there is so many upgrades and trick i would not know where to start .one thing for sure is my tig welding lesson is now completed .
Sounds very promising. plan is to spend the whole day at the track and race in the evenning drags , its a special year as its the 20th anniversary and this is looking up to be a huge evenning event .
there is alot to do with the car as almost the complete suspension , brakes and driveline are new and untested . i need to start slow and get the car safe as well as figure out initial clutch and base settings before i spray .car has been run and is stable at over 100 mph and stops well but like i said at the track its all new again .
Safe is certainly always best.if all goes well will plan to hit it with between a 150 -200 shot ,fingers crossed
Likewise.now i got to remember how all this nitrous stuff works ,
did fire off the system the other day ,first time in 2 years .
static test from 3300 rpm jetted with the original dual pulsoid setup jetted at 8 psi with 20 fuel and 50 nitrous jets .
Those jet sizes are usually used with fuel injection pressure 35 to 40 psi, so how you've ended up at 8 psi I can only assume is due to excess fuel delivery through the carbs, so I'd be treading very carefully under those circumstances.
Just had a thought, maybe you have 4 fuel jets and 2 nitrous jets!?!?!?car reved quickly and cleanly on the static test to 7500 rpm with a A/F showing 12 flat which if i remember from past test is ok as it always show 0.8-1.1 richer than a road test .
Yes that sounds fine, so I'd be very surprised if you didn't have the jet quantities just mentioned.? anything i need to be aware of after the pulsoids sitting for so long ? should i dry cycle them or anything or is it a matter of checking for leaks ?
The greatest risk from Pulsoids being sat doing nothing for an extended period of time, is from the fuel decaying and causing the plunger seal to deteriorate. This deterioration can be in one of 3 ways (depending on the fuel ingredients);
1) The seal material goes soft allowing the seat to cut through it, leading to major flooding.
2) The seal material breaks up with the potential risk of jet blockage.
3) The seal material expands and reduces the plunger lift and therefore the flow capability of seat, which in extreme circumstances can entirely block the flow off.
These failures may not show up immediately you start to re-use them, so don't assume they will be OK just because they work OK now. The very least you MUST do is inspect the condition of the plunger seals and to be on the safe side I'd replace them with our latest PTFE coated plungers which have our latest material that is the most fuel resistant we've been able to obtain.anyway will keep you up to date .
and its great to be back behind the wheel as its been waaaaay to long .
Jim
Glad to have you back and looking forward to some GREAT results.
