My Barn-Find Firebird Wheelies at The Dragstrip! But Does It Run an 8 Second Pass?

Its flat out lazy

You know Mike, I really like this car and i really want you to continue with it. Sort it out, learn what it is saying to you. I honestly don't think you are gaining much, if anything from that blower. This might not sound popular, but a NA 540 thats well built but not crazy, should deliver similar if not better results at the track. Are you using pump gas or race gas ? If you are using pump gas then thats impressive, but if you are using race gas then i would consider getting rid of the blower, taking apart the motor to learn what you actually have, then putting it back together with about 13-1 compression, the right cam, and maybe a tunnel ram, and it will go faster than it does now. The parasitic loss of driving the blower, plus the weight of it is barely overcome by the power it makes as compared to a well built NA 540. As far as just plain coolness ya we all like the blower. In my area of Canada i can get AV gas cheap and i have successfully used it above 13-1 CR for a cheap alternative to race gas. I really want to see you succeed with this car. Its the first car I've seen in awhile that i think lots of gearheads can relate to.

I want it!! My husband always watched you on Roadkill and now I am like where’s Mike!? Miss you!

Will we ever see new wheels on rubber duck?

ONLY DIFFRENCE BETWEEN DYNO AND STREET IS G FORCE. MAYBEY PULLING FUEL OR OIL . ? OR GAS IN BOWLS. SOMTHING TO DO WITH FUEL BEING PULLED BACK FROM G FORCE OR FUEL REG

Rubber duck sure has come a long way since y'all pulled it out of a barn, Mike! I'm thinking a nice solid roller and upgraded springs would get you into the 8's... Good luck! Scott/The Bulletproof Garage

Who would wangt a Datsun????

Have you checked plug gap , is it blowing the flame out

When the valvesprings are the issue then it will be worse with the smaller pulley for more boost.

Valve float

You've got a consistent 9 second bracket car 😅 guarantee if you enter into a dyo class dial in a 9.1 it'll go 9.0. Then go for 9.0 and you'll get your 8! Always happens😂

I want to win the Datsun 510! I foresee a life of parking lot autocross for it with me, I bought some stickers so I got one shot.

Maybe the initial hit on the leave moves something in the concerter or in the gearbox and it jams something up. That would explain why it did not do that shit in the dyno. There its already rolling before the hit. Just a stupid idea🤷‍♂️🤷‍♂️

Advance the ignition. That will make more heat and clean the plugs and stop them misfiring......what do you think???

Almost acts like converter miss match or the converter ballooning

Ignition breaking down at 6100+ rpm

The fuel pump on the dyno is good. The fuel pump on the car can't keep up? Too much or not enough fuel? I chased a bad ground for a while.

If your A/F & timing advance are acceptable, the next is a compresdion and leakage test unless you are sure it's healthy. Next is valve spring pressure/condition & rocker are geometry. I'm sure as you check things off you'll find it.

Did I see a tie-bar? Then you have a solid roller unless I was seeing the lifter valley casting?

Wonder what its like....maybe next life Best wishes

Injection is nice but id rather be blown

Need to change the highspeed bleeds...

Check them with a drill bit gauge...

A glogged air bleed can cause a problem.

Don’t sell the Datsun

That msd box has a rpm trac it just enough to see you converts sliping. And if you here it breaking up the trac will show if it's spark

Few very important tricks for running Carb s float bowls sock dry you need larger needle and seats .surge tank

Put a fresh alternator in it buy a lightweight lithium race battery that runs at slightly higher voltage and maintains higher voltage upgrade to charge cables from the alternator engine block ground and to the battery Big Three check your ignition box sounds like voltage issue to me

Why doesn't NPK racing switch to 1/4 mile. They should everybody get back to 1/4 mile REAL drag racing, if you are at the track.

Cant afford a dragy?

Boost pressure pushes against the back side of the intake valve, so you're going to be losing roughly four pounds of effective seat pressure for every pound of boost so valve float would make sense.

The senior moments are real, Mike. Embrace it, learn to love it, and chuckle with your friends when they happen.

* I'm interested in the 510.

KISS , restricted fuel, something is lowering the volume

You said it Mike a quarter mile is a real Drag strip 1/8 of a mile is for burnouts

I was always told to keep going up and Jet size until fuel leaks out of the tailpipes then back it up one LOL sounds funny but it has worked just enjoy a nice day at the track assholes took away my atco dragway

Mike you could use some good news for a change 🤣✌️

Whrn you caught the ignition in a previous show I thought you could do with moving it. Probably not the problem you are having though. Good luck with it.

Whats the blower tirbines like?🤔🤔🤔

The tuner guy said thats were the o2 sensor is happy i thought mike said it didn't have one🤔🤔🤔🤔🤔

Hey Mike, Even though you are scratching your head, for us watching this is just 100% fun. Keep on keepin´ on and you will figure it out.

Never make a TNT pass without a Dragy at minimum. Why risk your car on a full blown pass relying just on the track system. And it seems to be long past time to take the motor apart and finally see what you have.

Everything seems to have gottennworse after he had the carb work done. Maybe go back through them.

how long can you hold the gas pedal down? 250mph?

nice looking 510

Yes valve springs
