sorry for the late reply guys, the system bliped and i did not get a notification e-mail
Marc, is this going in the MR2 chassis? The turbines in the frunk? Oy. I like it. Is the plan to just throw the E153 in neutral when you switch to turbine power?
I'd suggest giving more early thought to the fuel tank situation rather than later. Jay is definitely tightening up the fuel cell regs going forward and if you're using the MR2 chassis, you and I both know that you don't have a ton of spare room to handle packaging issues.
it's going in the same red MR2 chassis that had the radial. it's already got a really nice cage in it so it's one less thing to do.
the plan is to have the turbines to augment the power. i could drive on turbines only with the e153 in neutral since it's oil pump is driven by the ring gear, but likely it'll be in triple engine mode most of the time.
I thought his original plan was to stick all of that in the back where he had the radial, and both using the same gas tank for fuel since turbines can burn pretty much anything. Not sure but thought it might be the OE tank.
yeah, the MR2 is super tight, if they run well on gasoline i'll just use the OE tank. it'll give me about 20-25minutes of runtime between refueling.
Actually now that I look at the diagram (with the benefit of a glass of whiskey in my hand), I'm betting that what we're looking at is the Toyota motor/transmission in the proper place and the gas turbines in the trunk proper. Which means that he could run the stock fuel tank in its stock position to fuel the gas motor and a smaller fuel cell in the frunk if he wants to run the turbines on kerosene/diesel/biodiesel/JetA.
Like I said, give this some thought early, Marc. Having been down this road for a fuel cell in the SIMCA/MR2 chimera, the frunk is smaller than it seems due to the mounts for the front strut bars and the front LCA's (so you can't compromise going forward and down) and the brake and clutch master cylinders (so you can't compromise going back and up). You would think, hey, just cut the floor out and there's gotta be plenty of room there! But there's less room than you'd think, and most off-the-shelf fuel cells don't want to fit there.
However, if you aren't opposed to moving the radiator out of the front of the car, there is some additional room, but you're going to have to find a really short fuel cell to make it work without interfering with the front strut arm mounts AND the brake/clutch master cylinders.
you got it, it's all going in the trunk/engine bay. it'll be an exercise in origami! the goal is to get the engine lid to close also, but i won't feel bad if i need to make a hump for the turbines.
i will definitely fit a fuel cell up front if nothing else for use on the street. the only question is if it has to be removed for Lemons. but that's not a discussion for this. it's a safety tech discussion. i don't expect to be able to fit a very big tank. the brakes and the clutch can move inside the cabin with reverse mounted masters and the power steering stuff can all be removed. with a custom cell there is enough room for 25gal up there. without a custom cell i can probably fit 10-12gal which is the way i'll go. the passenger side floor would be ideal but i think that's an insurance no-no.
also, for what it's worth, i would like nothing better than to run a diesel engine in here. so if i somehow can arrange that coming from the UK, as long as it's the 2AD-FHV so it does not complicate any of the other stuff additionally, i'll definitely go for it.
