And how does a F1 motor compare too a top fueler?
There is no substitute for cubes…
Oh well since we have trashed and hijacked the thread I guess we can now have a bit of fun.
.Eg...if you spent the same effort, on a say, a 502ci as is on a pissy little gay F1 plastic....what would be the result????
Well of course if you put it that way. Goes for any engine. As most internal combustion engines, roughly 30% of the fuels energy is going straight out the exhaust pipe. So volumetric effecientcy increases with turbos, we get somthing back.
We can't really compare a 2011 top fuel engine with an F1 engine of the 80's(sorry Krankin I should say gay plasticy F1 engine
but I'll do my best and have some fun trying. Both have some really wierd engineering. Power per cubic cm is similar to an F1 tubo engine. I think around 8000BHP for an 8200cc engine. Pretty impressive stuff!
The F1 turbo engine was a not very far behind around 1300 BHP for a 1500cc engine in quallifying tune, boost pushing 5 bar which by no supprise is the around the same boost of the supercharged top fuel engine. (no supprise as both engines apart from being wildly different in configuration are near or at the maximum theroretical output for a internal combustion engine of it's size. There actually is a formular for it called P.L.A.N.)
Over the years there have been some wildy exagerated claims for the turbo F1 engines but the real figure is as stated above.
It was 86 that saw the bigest outputs before pop off valves were introduced. It was at Monza that year when the BMW in line 4's were peaking over 5.5 bar which would of equated to over 1400BHP, there dyno's only went up to a 1000BHP. Again, some pretty inpressive stuff particularly for 1986. You might be thinking ah but that is in Qually tune but remember the expected life of both the top fuel and the F1 enigne would be around the same. In minutes and not to far into double figures at a guess.
In race tune they were around 1000BHP, a still creditable 750BHP per litre.
Fuel was qutie different, 100 octane petrol for the F1 donk, alcohol and nitro methane for the TF. I wont go into it, im not a chemist
Now days, your probably right Krankin they are a bit gay and platicy. Back then the engine way overpowerd the chaisis. Which made for great racing.
