1000HP F4R+T (nearly there) from chris at EFI parts

Video link not working but caught wind of this on the vx220.org forum where one of the guys who had standalone posted. Fantastic achievement and looking forward to him smashing his personal best
 
yeah i cant get a link to work unfortunately. savage considering it has more to come! if it hooks up its an super low 9 sqm, has the potential to break some serious records. to be fair its got to be the most powerful f4r out there
 
Is he running on ethanol now?? Just wondering as it looks like he's wearing a face mask in that picture??

863hp and 44psi
996hp at 55psi :o

M1 Methanol at 99.95% purity by the looks of it, which runs at about a 4:1 ratio whereas Petrol would be 12:1. Technically Petrol has a higher energy density per unit consumed but you can burn three times more Meth per power stroke, so even though Meth is just over half the energy output of petrol, because you burn three times more of it you get ~60% more power per power stroke.

I don't know what injectors he is using but I know they are massive, and there are two per cylinder!
 
From the horses mouth...

This latest iteration consists of a Clio 172 engine block and a Clio 200 cylinder head. Everything is worked of course. In a nutshell: Concrete filled engine block (no water), my own design 20mm thick girdle plate/main cap brace, I-beam rods, forged pistons, dry deck cylinder head, electric water pump for the head only, solid lifters, custom cams. VVT blank, 2x 2200cc injectors per cylinder, GTX4202 turbo @ 55psi and running on methanol.
 
Concrete filled engine block!? WTF!? Never heard of that before... still when you think about it, (FWD Extra Traction because of the massive weight increase, Additional Density and Strength to the block) it makes a lot of sense.. Only concern is how the temperature will effect it?

Look forwards to see how this thing goes at the new resurfaced Santa Pod..?
 
concrete wont add too much weight to the small water ways its more a strength thing. cooling is less of an issue on methanol also plus the car will probably idle very little and be turned off very quickly after a pull on the dyno or strip so keeping it at temp isnt too much trouble either
 
For the amount of cycles it does under power, it won't. A lot of drag cars dont have a cooling system at all and make do with having static water in the block for the few seconds they run at max power, plus the oil will help cool the bottom end a bit too.

Yeah - the evaporation of the methanol in the cylinders will produce a massive cooling effect. The Top Fuel engines are solid and purely rely on the latent heat of evaporation of the Nitro to cool things.

Hmmm, I suppose there’s not a lot of water ways in the engine?
