Well this guy just told you what it is.

But he has the engine and pump tuned.

Ive never hit a 100 in my stock 617 tho

__________________

I have more HP (230ish from my last dyno run and I now have a much bigger turbo). Remember that stock they make 126 for the best numbers I've gotten though you'll hear other number but it's in that range.


With the second turbo and the Dieselmeken pump I've run a best of 136.2, running 26 PSI boost. When we get to the track post-Covid I'm shooting for 150 with 40 PSI though there will be more than a little tuning to get there.


In stock trim I ran a best of 96 or so with the stock pump and stock turbo but with a manual boost controller and Greazzer's nifty injectors which I'm still running. I have no clue what the coefficient of drag (cd) is on the Mercedes body but the S10 is .25 (IIRC) according to the Interwebs, basically a brick.

Actually .25 is very good. I'd suspect a Cd closer to .4.

..I also have a 427 Cobra replica with an aluminum chassis.

I have it written in my log book which is in the shop and I'm not (I'm recovering from a nasty finger wound from improperly cutting aluminum angle stock on my chop saw - don't do that with the V pointing up). When I get back out there I'll look it up but that's the number that came to mind. I used whatever number it was in Dr. Mayf's calculator for HP derived from speed and it was pretty darn close. BTW - I think those equations are still on Landspeed.com.

I don't think these cars were made thinking of them as Hot Rods....

However, before I had the I.P. rebuilt my turbo 617 in my '84 California spec. coupe easily went 125 MPH by GPS, I'm scared to drive fast but I had it up faster once or twice in the Desert late at night on a long flat empty straightaway .

God help you if a coyote runs out in front of you going that fast .

My '82 24D topped out at 83 MPH per the book before I had the I.P. rebuilt , I don't normally thrash my engines like that .

These are excellent cars to drive very quickly, they make wonderful high speed touring cars but if you have the need fo0r speed, skip the old diesels .

Then your stock OM617a is sick. 100 mph is no problem for a healthy example.
