I was not trying to be an ass. i just get tired of all the inflated dyno numbers on the net. i noticed you new post and remembered your 1397 post and was just asking why not much difference. i have been following your posts to get sum kind of idea what these big motors will make power wise. i was even thinking aout doing one. i dont want to spend 2 or 3 grand for 15 more horse. then brian gets mad and talks about my motor. i never said anything bad about your motors or bikes. i think you guys do good stuff and you have a great rider. i was just posting what i saw you guys post about your motors. let me give you sum background on my motor . it made 216 hp on your dyno. so if u say 220 is he normal then thats not to bad for mine. i built it to ride everyday in any heat. its never been to the halfway mark on temp gauge and runs on 89 pump gas all the time. i put 10000 miles on it in 2 summers. i took it apart to freshen it up and it still looked new so i did not change the combo. it has been a great street bike that gets riden everywhere. so 216 hp for 3 years without a single problem is fine with me. i bet it makes more then 216 now that it has new injecters in it.i wasnt knocking your stuff just posted what i saw.

I wasn't mad. I just want to compare averages not, the best we have ever seen, that we are having trouble duplicating 1397, vs a good 1507. Your bike is on par with a good 1397. If you compare it to this 1507, we picked up around 20 - 25 hp and 14 more ft/lbs of torque. Not a bad gain and I don't think it would cost 2 grand if you did it your self. We have two others we are building with different components to see what the results are. All three of these bikes have different uses in mind. Stay tuned for honest results. We will never exagerate dyno numbers. I would be happy to send the run files to anyone. This is only the first of tests. The street and track are other proving grounds.

Sorry for the misunderstanding.

Bryan

No problem

If you guys want you can still edit your own posts and remove offending info. These posts are not old and not everyone has seen it yet.

bhartley · « **Reply #53 on:** March 22, 2008, 05:22:32 PM »

all removed. im done.

In the grand scheme of things it doesn't matter who's motor it is. Quantum Motorsports will continue to do R&D and build the best engines we know how to. Sonny will continue to prove them....

I think as far as peak numbers we all can agree that a good 1397 makes 215-220 hp. This particular 1507 makes 239 peak hp. This thread was not started to be pissing match. It was created to inform people about 1507's. An engine package I don't see advertised very much and is the next logical step for someone with a 1397.( Assuming they are wanting to stay naturally asperated.)

Nice, flat build to peak. That autta make for nice shift recovery power on the track Steve.

This thing is gonna fly...swb, the numbers could get silly

BRYAN · « **Reply #58 on:** April 02, 2008, 08:11:08 AM »

We shoud have some shake down numbers this weekend. It will be interesting to see if Sonny can control the power in SWB form.

Just curious where you all sent the crank off to, if it's not too top secret.

Have you all recieved it yet? If it's nice and Shiney, and you do not mind show us a pick of the weld area.

Thanks

We are in the middle of building my engine and the modified crank is resting in reworked cases that have, among other things, been align honed.

We are expecting delivery of another 5mm in two weeks or thereabouts and when we receive it I will be more than happy to post pics.

Our sources of supply are not top secret.............we simply choose not to discuss suppliers.

In some cases suppliers do not want to be indentified out of fear they will be bombarded by phone calls from retail traffic with whom they typically do not deal with.

No worries mate. Bombarded by cranks, thats too funny.

If its a Marine Crank weld up no need to post pics, cause them
things look like they have never been touched!

i built a 1610cc last year, with weld up falicon crank, carrillo rods, big in/ex valves head by kws, web cams,. 110 lobe centers,... power was limited until we installed larger injectors, engine makes about 250 hp, runs low 5's in 1/8 still going strong,... thanks kevin at kws

Great information on the 1507.

Any development or information on a 1510 (1464 + 2 mil 08 crank)? Just wondering what that combo would look like.

Im building one as we speak.... Waiting on roller cam chain kits to come off back order again...

Its going in MY streetbike so it wont be squeezed real tight because I want to ride it daily but it should be a fun torquey motor .

ras31 · « **Reply #66 on:** April 17, 2008, 11:11:02 AM »

Are you going with large cams? I am thinking about Mega 410/385, street bike.

Steve S · « **Reply #67 on:** April 17, 2008, 11:36:30 AM »

Sounds fun Bill. Ras, at least go with the .415 which offers both a little more lift and duration. Strokers tend to like duration.

crazybill · « **Reply #68 on:** April 17, 2008, 05:09:39 PM »

Im just going to say yup

Mike Barger · « **Reply #69 on:** April 30, 2008, 07:47:13 PM »

Heard that 1507 was tuned by quantum motorsports. I know it has only been 9.teens at 156 mph with the owner on it at two different tracks.wtf

Have you guys had a chance to run that beast with an arm on it yet?

BRYAN · « **Reply #71 on:** May 12, 2008, 10:13:48 AM »

Hey guys just an update. The bike is brutally fast. We have had a lot of problems with traction. The bike is geared to go 170+ in fourth. The shift light is on going through the traps if this is any indication of how hard the bike is spinning. Sonny is also having trouble getting the throttle pinned because the bike is so violent. We are changing the gearing, had a weight made for the front, and added an aftermarket steering damper.

Hopefully we will have ne results soon. Weather permitting......

Sweet. What gearing were you running and what are you going to try next?

17/41 was the gearing we have been trying. 17/38 is what we are going to start with.
