im sure you tried this but my have to do with back pressure from the exhaust try routing the exhaust as close to stock as it was before hopefully helps it run better

Did it have a FMC fuel management control unit that worked off a mass air flow sensor mass air flow sensor triggers the fuel pump to go into surge and produce more fuel pressure under heavy boost just a thought great videos

I just thought I would throw this in, Triumph Spitfire rear wheel axle flanges are on a taper and keyed. I've seen the wheel and flange break from the axle in racing situations. I know because I used to build Spitfires and MG midgets for racing. I'm not sure of your plans for the differential area but don't weld the spyder gears, get a Subaru 4 wheel drive rear diff and CV axles and install that as a unit. I'm J & J Racing, LLC in Sherwood Arkansas, email if you want to contact me. All the best.

Electronic rev limiter? Purchase a swing spring rear suspension to eliminate the back wheels tucking in under when the back end lifts.

It’s because u don’t have any sort of back pressure? Maybe that’s why it ran better with th exhaust in it

Friggin Awesome, period.
Guys I may be way out of line for even thinking about potential solutions here for your mastery but something is telling me electronic engine management system like some bizarre grounding from the snowmobile throttle switch or something, forgive my stupidity, my next advice from the lantin is to take it to the snowmobile manufacturer and have them do it under warranty ! Hehe Reversing this beauty into their service dock they probably be pleased to help... I would.
You'll figure it out I believe in you ! Keep the faith my brothers...

I’m assuming your issue is the fuel tank being in the rear. Not getting enough possibly?

It sounds like the carburetors are out of sync. Or a pilot jet is clogged. It needs the exhaust to be on. That's not the problem though

Yo guys, love your work as always! Would love to see this finished and in British racing green! I grew up around these cars and I think that what you’ve done is awesome! Needs a roll cage/full suspension rebuild/thicker tyres and generally a complete clean up but I think this will be something genuinely special when finished!
Keep it up!

That car is insane. These snowmobile engines today are way too powerful. I had a sled from the 80s I think it was 50HP. Went 55 MPH.

That tree house and bridge makes me think of the video game The Forest where you can build tree houses and link them with these bridges.

And PLEASE cover that clutch and drive shaft. You have a 200 HP meat grinder there.

Love this project... can't wait to see it when you get it tuned and built up! My buddy had one in Highschool with a chev 350 and Corvette drive train in it that he robbed from his Dad's crashed vette... He and his dad built it in a month and the thing ripped and was scary as hell... beat my stroked 1990 Mustang 5.0L easily. Never got a hood to fit around rad and motor...
I like the fact the hood completely covers the sled motor to keep people guessing. I'd reinforce the frame and build it like a 2wd prerunner... put a roll bar and side crash bars on that thing too. Hitting a tree with that thing even at those speeds will tear that thing in two. Keep sending it 👍

Get a trans tunnel and driveshaft loops on that thing. That's not okay.

Have you guys dialed in your clutching? That would certainly hinder your top rpm range. Especially since youre turning a driveshaft and wheels now instead of a track.

When you go boost you need more fuel. You're leaning out when you hit boost which isn't letting it Rev out because your afr is way off.
