2008 Dinan Stroker M5 versus 2009 Cadillac CTS-V - Page 8

How did I miss this thread? Nice run Darren - looks like your beast is pulling nice and strong... you gotta be a proud parent....

So now I am even more ticked that my beast malfunctioned in the big "D"..

Anyway.. the dyno subject.. Both cars are naturally aspirating engines.. How can we discount one of the cars dynos, but not the other?

Just a question....

I know there was a vette video in here (nice run btw

), but I think we are all still trying to see a Z06 run just for comparison to see what lengths you have on each other.. It's a good baseline for the NOS system, and for the ASR consumer - it would give them all a great determination as to how the outcome would turn out. I know exactly how my car reacted / beat the Z06, and could give a completely fair and honest opinion on how I think the outcome would be.. Unless anyone's willing to trailer their car anywhere? Anyone... Anyone... Bueller... Bueller.. you there?

I know when my car is ready I'll be game to go pretty much (within reason) anywhere to have a little fun, and of course have a mighty toast when the deed is done..

That car has so much potential it is crazy... When that thing is tuned with a pulley I will be scared...

First, your car is sweet....(and Darren's!)

It is difficult to compare NA vs. forced induction motors, as Ranger points out.

The new Ms will likely be forced induction in which case, tuning will be available..... I don't look forward to the loss of throttle response but I may be persuaded to look the

other way with a 100-150hp $2000 software tune.

If I am not mistaken, the CTS-V does not have the forged internals of the ZR1 motor. It may be capable of the 600-700rwhp.... but it may not be a long-term proposition.

If you're referring to Darren's car and the CTS-V, the Caddy is a supercharged car, not NA.

Unfortunately, the tuners will most likely charge twice that amount when they see the M badge. They will claim that they need to be compensated for all the R&D..and all the other bull.. Exactly what they say when it comes to the MB V12TT...they charge astronomical prices (i.e. RENNtech $5,800) because they know that it is such a huge increase in hp that they will not be selling too many other performance products for that application....so nail the consumer while they can.

At the same time, hopefully the relative ease at increasing horsepower through software applications will inspire some healthy competition among a number of tuners, thereby driving the price down. The will be some risk, of course, in getting work done by new and yet-unestablished vendors.

Very true...

The CTS-V is supercharged.

Correct, it uses the same block but there are some significant differences on the internal make-up... piston, rods, dry sump system, super charger.

CTS-V uses a motor callled an LSA
ZR1 uses a motor called the LS9

The hypereutectic pistons are fine for a safe 700rwhp if tuned properly.. There are many S/C LS2 and LS3 vette's w/ over 700rwhp that are daily driven without a meltdown..

I'd like to see a comparison of darrens car on a dyno with and without fans specifically feeding the air intakes (outer inlets on the front bumper). I think that alone will show how airflow makes a difference.

Also, I will trust Dinan to come out with a reasonably priced tune or the new M if it is indeed forced induction. They only charge between 1.5 and 2.5k for the 335i yet it's about the same for tunes on the other newer cars. I don't see a tune costing more than it costs for the S85.
