Thanks for sharing!

Oh brother whats the big deal about the car? Big turbo yes but I dont know if you guys realize this or not but Abel says his 3 rotor makes 15-1600rwp and thats on a damn 3 rotor. He has done like what 6.7's ?Having a 4 rotor that can barely brake 6's but hasnt yet is not impressive infact it makes rotories look somewhat week.

Don't forget Abels cars have both been tube chassis cars with fiberglass bodies if not carbon fiber "Much lighter!!!".

The first time out, the BMW ran 8.2XXX, then they made a few changes and ran 7.2XXX ( A full second) give them some time

yeah, the bmw is alot heavier then abel's car, not only that, but the car was actually built as a show car first, only later did they really become serious about dragging the thing, with a bit of work we should see it at least dip into the 6's

I'm pretty sure a 4rotor making 1500-1600 HP, will have more torque than a 3rotor making 1500-1600 HP. And lets face it, torque helps!!!

did he make the 4 rotor, or what? thats ******* nuts that he has the skills or at least the people to make a proper 4 rotor rotary. The ones i've seen have all been very limited in power, and some 13b-rew's have had higher Hp than the homemade 4 rotors that I've seen.

amazing.

The car being heavy is not a valid point. I was trying to say that abel's 3 rotor makes the same rwp then the 4 rotor. It would be impressive if they can gain the extra 25% with that extra rotor. This would mean the 4 rotor is capable of 2000rwp + mabye couple hundred more. So do you still think 1500rwp is alot for this thing? No way hoe zay.

That what he says, beside what good would it do if the engine has to be replaced after every single pass?

Yes, true to a point. The powerband of the two cars must be considered. Thereotically, if both cars would run on the street (and traction weren't an issue), one would prefer to have the 4-rotor over the 3-rotor because the torque would come on earlier in the powerband; however, when we're talking about dedicated drag cars that have automatic transmissions and are geared to always be in their powerbands, if both cars are making close to the same average whp over the powerband (say 5k-8k RPMs), they would be equally fast assuming equal weight and gearing. The cars are going to be launching with boost anyways with some kind of two-step rev limiter and I'm sure the stall on the auto will be somewhere in the powerband. If each car were required to just start from idle with no powerbraking, the 4-rotor would have an advantage because it's torque comes on earlier in the powerband. Anyways, just my .02.

Here we go again. Abel doesent replace engines after every pass. If you were to actually read up on the stuff you would hear otherwise.

You do have a point that if they blew up a 4 rotor they would be out of a lot more money. However, im guessing hes pretty rich to begin with.

My guess is that they are slowly ramping up power output to be safe. And just because they have money doesn't mean they are willing to just throw it away for no reason.

Man why are you such a hater? Yes I do follow up on Abel and he is working out the bugs to make his motors reliable and consistant. And the key word is consistant that's what wins races and championships. And if you would follow up on the BMW you would see that it is consistantly improving it's times. Not impressed with with a low seven second pass than hell you must have one hell of race car yourself. You'll be one of those bandwagon jumpers when that BMW gets dialed in and running deep into the 6's.

Hater? lol okay! I just said I wasnt impressed with a 4 rotor that doesent make any more power then Abel's 3 rotor. How the hell do you get that confused with me hating something?

And I did not say I wasnt impressed with Abel you read me wrong there drrr.

I did not read you wrong I understand that you are not impressed by the BMW's performance. And on your quote "Big turbo yes but I dont know if you guys realize this or not but Abel says his 3 rotor makes 15-1600rwp and thats on a damn 3 rotor." Abel has never said his motor makes 15-1600rwhp he states that his motor is capable of 15-1600rwhp. And that he is working to get his car in that power range and to be reliable at that power level. And no one has shown what kind of power that BMW is making. Yes you can guess but without knowing the weight of the car you can't get an accurate estimate of horsepower from the E.T. and M.P.H. Besides that once you drive/build something over 160rwhp maybe then you can talk. Maybe...

wow, that's a tight fit. Wouldn't it hit the chassis when it torques over?

Highly doubt it would hit it's a race car and most likely the engine and transmission mounts are going to be solid.
