How much did you pay for that package?

Those are amazing gains in torque for the Renntech kits. 
That car must pull like a freaking banshee.
Although, it does appear that the stock RWHP #'s are a bit on the low side. I would think they should be around 500+ rwhp.

SL65, 911
Sheesh, very nice! My airbox arrived in the mail today, and I'll be installing it this weekend and hitting the dragstrip again next weekend.
The reason the dyno #s aren't what you would expect is presumably because this is not a dynojet dyno. The relative gains look correct.

Treynor - Can't wait to see your 10 second timeslip.
Were you running drag radials when you achieved that 11.3 @ 127?

Have any of the '65 owners with the ECU mods had any issues with the transmission, as I know AMG limited the torque to 738lb.ft to protect this.
Just doing some basic research before I start modding my '65 !

no transmission problems, but with that much HP and Torque they recommended we send the car to Renntech to have the tranmission upgraded to give more support and smoother shift patterns

Thanks for the info guys.
Just one more quick question, as i'm in the UK, Renntech is not easy to get hold of, but Kleemann is easy to come by.
Has kleemann got an answer to the work that renntech do, or would it be worth me shipping my ECU off to renntech to get the upgrades done and give kleemann a miss?
Thanks in advance, Matt.

What does the trans re-buld option cost? I though the only trans upgrade they were offering was the TCM upgrade that is included in the ECU package? Is the trans re-build a custon thing?

Since the ECU mod supposedly can't be seen by the dealer it doesn't seem to effect the factory warranty but I am sure the airbox is very different. Will something like this give the dealer an easy "out" on the factory warranty if something actually did happen?
