    So you are pulling the kit to start production, or revise the manifolds?

    Yes I know. My question is the reason for pulling the kit. Revise the manifolds and do more testing? Or just revise it and send to DOC?

    Start production, the manifold revision is basically telling Doc Race to use 1.25" Weld els instead of 1.50". A bit of interesting reading in this thread about 1.25 VS 1.50. I wanted to try 1.50 and see how it spooled, its bit slower then we wanted so production will be getting 1.25. Its not uncommon to pick up 80+ Ft Lb's of torque down low and mid range going with 1.25". Most all of Full Races manifolds are 1.25". Doc Race let me know their supra manifold is 1.25 and is good for 1300 HP so it will flow plenty for what we need.

    Sounds like a plan! Good luck.

    Haha I don't think it will block it. If someone re-uploads it i'll post it in one of the threads. I think Shiv just talked Jason into blocking the letters at the end of the URL so it can't be posted... Maybe I could tinyurl it?

    Just re-upload it and post it up. I don't think tinyurl would work.

It should be running much more than 10.82@131.99 imo considering the amount of power and the gutted interior. The RB turbo JB4 cars are not very far behind it's record on dragtimes and they have a lot less power.

    Speaking of bias, Shiv is the only ST owner to take their car sub-11s.... On Hoosier DRs, a Race Driver's Seat & No Passenger Seat.


    Meanwhile, LM's 11.1 run @ 127.2 was run with a stock frame turbo (RBs), basic bolt-ons, a Wavetrac diff some MT Street Radials. It's much more likely someone replicates this performance with the same setup then Shiv's.

    There are lots of RB cars running low 11s. I managed 11.1@129 at Famoso (not a fast track) with minimal effort and a bad 60'. If the trans allowed it no doubt it would be in the 10.80 range. Click here to enlarge

    Exactly why I can't wait for you to get the VT3 kit. I say install it on the E92 6mt instead of waiting for the AT build though. I'm sure you will be able to easily beat the ST times with the kit

    Yeah... We'll see. It's tempting. But, someone has to pioneer the automatic performance. The vast majority of our customer base is automatic. Maybe the best thing is to throw a set on both cars. Click here to enlarge

    Gutted? Click here to enlarge Removing a passenger seat (which was likely done to fit the extra set of wheels w/ DR's) saves ~45-60 lbs, not really a big deal and wouldn't suddenly put him in the 11's.

    Your example of "bias" makes absolutely no sense. Shiv running that time in his car (with the modifications listed) has no relevance to other ST owners matching or besting that time.

    The car makes power, there is no denying that (dyno graphs prove this, 60-130 times prove this, etc.). Launching a car like this isn't easy though and does require practice, DR's, and some luck. Comparing the ST car to a RB twins car, it's obvious by just looking at the dyno graphs that the ST car would be much harder to get off the line. Thus the RB results are much easier to repeat. Also because the power comes on so soon on the RB cars, an automatic can easily get in to the powerband just rolling off the line and get a quick time.

    Using a road racing example.. A stock E92 M3 driven by a professional driver (Randy Pobst) at Laguna Seca did a 1:42.96 lap time. The majority of E92 M3 enthusiast drivers at Laguna Seca are running 1:47's and these cars usually have modifications. There is one E92 M3 that just dipped in to the mid 1:42's and that car has upgraded suspension, big brake kit, R-compound tires, etc.. Just because the car has the power and is capable of running certain times.. doesn't mean it's going to always happen.. nor will it be easy to repeat.

    It's going to be really interesting to see the initial runs of the Vargas Stage 3 cars. Looking at the powerband from the initial graphs posted, it's not going to be easy getting it off the line. If you can nail the launch it will definitely be quick as it's making power in the upper range. The results of the ST car shouldn't be knocked though as it's certainly not as easy to do as the RB cars and I'm sure we will see the same with these Stage 3 cars (if initial results at the strip are shared).

    This is great progress, but there's a parameter missing from the picture: Heat.

    The more power you make with an engine, the more heat that it absorbs, and must be dissipated by the cooling system. Are there any upgrades planned to address this?
