The WERKS TLB7 Pro version is a turbo plug engine versus the TLB7 standard plug. The motor has more power throughout the band. Crankcase and carberator are new too. It is definetly different.

Ive seen 2 run so far, both after being just broke in and race tuned. They are powerhouses, I run a regular B7 on a 2013 pipe and was being pulled easily on the straits. I cant comment on the bottom end as I didnt drive them, but they looked like they had plenty with some reserve.

Both B7 pros were running Werks 2013 pipe as well. Cant give you a life expectency as the mill is still new, but on my regular B7 im on my 5th gallon and still have mechanical pinch. It runs just as strong as wehn I first broke it in. I figure it has another 3-4 gallons on it before it weill need to be pinched. So where looking at a 12 gallon motor if the bearings and rod hold up.

This new B7 should riiiiippp!! I've have a few B7's and I think this new B7 Pro is awesome! It's the Werks B7 version of the OS Speed V-Spec. It's changed in much the same way as its OS counterpart. "Modded" crank with tungsten alloy insert on the crank cheek and silicone ramp inside the intake port. Revised bore/stroke ratio (stroke is now longer). Revised port timing. Revised block that has been stiffened and coated black. New carb. It's all new. I don't think any old B7 parts carried over! And I don't think any B7Pro parts will work in the old B7 block with the exception of the carb.

Wicked engine! I'm definatly getting one! I have a thread going here in which Werks tracing responds:

also has any one tried the B3 PRO for $210 usd it's very well priced has it got the same mods as the B7 PRO ie lightened and ramped with an epoxy filler. The face of the crank of course is fluted and has been balanced with a tungsten insert

Awesome. I got about 12 tanks through mine it is just starting to loosen up a bit. Its already about the same as my 21-5 and that thing rips. I cant wait to put a real tune on it. Im running a 086 right now but Ill have to try the 2013. Ive been putting off droppin the money thinking maybe theres something better but 2013 is all i hear from everyone

Can someone tell me what the tuning characteristics of the new B7 Pro are? Sounds like they have power to spare, but how easy are they to keep in tune?

What plug seems to do the best in this engine?

Does anyone have more then 2 gallons through one of these yet? How is it holding up?

Thanks for the input. A few of us at the track have had a recent run of bad luck with O'Donnell plugs. Seems like I never had problems with them until recently. I thought it was me at first until I started asking around.
