Let's talk turbos. (review and discuss)

Thanks for the info. I suppose in time, we will see what their capabilities are. We did a set in Sweden for an RS4 and while the reviews were that the car was fast, apparently it didn’t compare to a Loba setup (but it seems that nothing does). Too bad those are so damn expensive…

I think 605s are certainly very capable. I started a thread surmising that the tuning was holding them back (basically EPL cars that have hit the strip seem to under-perform).

To bear this out, we have seen 2 605 cars in the 11s at the dragstrip

  1. notorious VR - 11.9 @ 116 (self tuned)
  2. that guy on AZ last week - 11.4 @ 125 (self tuned)

and a bunch more EPL tuned cars in the 12s. Could be co-incidence…but I don’t think so. EPL appears to know how to make power in gear, but when tuning these cars, there is SO MUCH MORE to it than peak power or the curve. Throttle dynamics alone can make an otherwise potentially powerful car look silly.

The only other data we have is that PBOX run done by tweets4estate a few weeks ago. He ran his car, trapping around 130 MPH…but again that was on pbox (and his car has just about everything done to it you could do, including 3L, fully built etc). If I recall correctly he was also on a downhill slope, but I don’t remember the margin. His time was 12.1 because he wanted to just roll out and take it easy. It was 26 feet downhill though which is MAJOR at -2%. Imagine a dragstrip where you start/drop in like a skater on a 26 foot high ramp vs. a guy starting on the flat. He’s fucked.

Thanks for posting that link Saki, I missed that before. Hopefully tweets can squeeze a bit more out of his car, but the setup looks awesome so far.

You can probably take a 300 mile drive up to see it…it is at/on its way to AMD to be fixed. Blown head gaskets.

Oh the glories of the B5. It looks like we will be bringing in the original RS6 turbo’d car from the Sport Compact Car Shootout to tune it for full E85. Hopefully I’ll have some more updates soon, I want it to be at Shift Sector in November as well. We’ll see what E85 and RS6’s can squeeze out on our Mustang, stock bore with rods.

Make sure you post up results on here. I’m interested to see what you guys come up with.

Still waiting on this car to come back in for retuning. Josh what do you think of 770’s compared to RS6’s? I’m getting ready to do a motor pull and I’m strongly considering doing turbos while it’s out. I’ve always loved the idea of RS6 hybrids with some billet 2283 wheels and stiffer wastegates, but I can also get a good deal on some 770’s.

From looking at boost profiles of both, the 770’s look to only spool around 200 RPM later but allow for way more top end. Seems like a good tradeoff to me. I was talking to the guys at AU Tuning about that 3.0L 770 car you’re tuning, but it’s hard to really get a good comparison since it is only on a pump file right now.

Thanks for the review Jude, it’s refreshing to see an unbiased review for this platform. You had one that was similar over on AZ, it was awhile ago but I also found it helpful.

Side question:

Has “JHM” tuned any 770’s?

Edit: I’m an idiot, this might have been the review I read, just noticed the dates 2012… Happy St. Party’s Day!
