Hi from across the pond, I'm hoping somebody will be able to answer my question.

I’m creating the engine sounds of a a '1969 Charger R/T Hemi' for a video game. I can’t for want of trying find the MAX RPM 'Red line' info anywhere?

I have seen a few interior pictures, that show what looks like a RPM guage that goes up to what appears to be 6000 RPM, however I'm not sure this was the 7.2 Litre 'Hemi' version.

Any idea what this Max RPM might be?!

I’m guessing low (ish) when compared with Camaro Z28 which I believe is 7500 RPM, but hey I'm probably wrong!

Thanks,
Dave

Right around 6K RPM for a stock Hemi. Too, at 7.5K rpm a stock chevy engine is coming apart as well, especially a big block chevy.

Thanks Todd, pretty much the RPM I was excpecting.

With regards to the Camaro Z28 - here is a bit of info I found on:

http://www.musclecarclub.com/musclec...istory-1.shtml

"In December 1966, Chevrolet then quietly released one of the most famous options codes of all time, option Z-28. Unpublicized and unknown by most of the buying public (and most Chevrolet sales people for that matter) and not mentioned in any sales literature, the only way someone could order the Z-28 package was to order a base Camaro with the Z-28 option, mandatory front disc brakes with power assist, and the Muncie 4-speed transmission. You could not order the SS package, automatic transmission, air conditioning, or the convertible. What you got was a unique 302 cid small block (Non-California emission cars were labeled MO while California emission engines were labeled MP) that was created by taking the 327 block and installing the short-stroke 283 crank. Specifically designed to compete in the Club of America Trans Am racing series which placed a 305 cid limit on its entries, the Z-28 was available to the public solely to qualify the car for racing. Advertised horsepower was listed at just 290bhp, which was not very impressive until one hooked it up to a dyno and got actual readings of 360-400 bhp. The Z-28 also came with a competition suspension, broad racing stripes on the hood and trunklid and could be combined with the RS option package. There was no Z-28 badging at all, lest it attract to much attention. The Z-28 proved to be difficult to launch on the street because its high reving engine was lethargic under 4000rpm and worked best when it was shifted at 7500rpm (!). Once it got going, the Z28 was tough to beat and boosted a 140mph top speed and numerous racing victories. Only 602 Z-28s were sold in 1967, making it a truly desirable collectable."

Hence, where I get my 7500 RPM from.

Jeez, wish I lived in USA, love the sound of these V8's.

Thanks,
Dave

Yeah forgot about the TA race motors. The 283 Gm motors could be spun that tight as well as the ford 289 HIPO. Dodge/Chrysler had a 300-ish ci motor for trans am as well.

Yep, 6K to 6,250 RPM's sounds about right for the stock 426 Hemi.

I belive the mopar engine was a 305. 340 with a custom short stoke Dan Guerney crank. As for the Z/28's turning 7500 revs it's very true. One friend of mine back in the day was turning 8300 thru the quarter mile traps with a 6:17 gear!! Oh.......it was his daily driver as well. I had a rather boring ride. lol 71 340 duster. Gold with the black stripes. custom interior with front buckets. My only mods were hurst competition plus shifter. Mopar 4:10 gear set. hedman headers. ran mid 13's at York US 30 dragoway thru the mufflers with street tires.

6000RPM would put you in the ball park. Here's 2 links, one being an actual Dyno test from 1965.
