toe to toe with a cummins!

[KyleQ]

I get funny looks when I'm flat out banging gears in my diesel. Sounds like a big block until I let it idle - open element air filter FTL.

lol. same here. 3" strait pipe into a 22" long, 4" chrome tip that kicks out in front of the right rear tire. i have no doubt a LOT of people think somethin is wrong with my truck as i come roarin by in cloud of smoke...

 

[Diesel_brad]

Are you sure the other guy was racing?

My exact thoughts

The cummins was driving like on his way to church and blown84 was acting like he was at the drag strip. Not exactly what I would call racing

 

[Danoflapper]

I've lost a race or two against people who had no idea I was 'racing' them. Hahaha

I get alot of people telling me my 460 has a fuel problem and a bad knock at idle (I don't have the Diesel badge on the front)

Or, they tell me my PSD sounds like a gasser

 

[dieselgiant]

Wow, I lost a red light race to 15 passenger van, I did beat a 94 Honda Accord wagon. 115mph is my personal best...downhill of course. One thing I like about our NA diesel's is we will never ever have turbo lag.

Having driven a 94 12V cummins with the 5 speed i would say the cummins accelerates the same as my 7.3 5 speed... *off the line* up untill the trurbo spools up but you can feel that they will pull harder giving a load. Having attemped to "race" the cummins and having "raced" my 7.3 the problem is that with the cummins it accels the same as the 7.3 then you get boost for a quick pull for like .5 of a second then you fall flat on your face on the low RPM governor. with the 7.3 you get more RPM to play with

 

[blown84]

the old 12v cummins were only rated at 175hp, and the 6.9 was 160. with only 15hp difference, weight plays a huge roll.

unfortunately, an 08 has a slightly higher ratin... lol.

 

[Alex S]

yea no i here ya but i was just making a point that we have the advantage of more RPM to play with. Generally diesels with manual transmissions are kinda useless for racing

I outpulled a Cummins coming home from camping yezsterday, he had a smaller camper and wanted to pass me uphill, I was in fourth 2k, 15 lbs, that is my sweet spot all the way to the governor, wife made me slow down. wimmen.
he had some work done as I could here him behind me, we were both coalin a little

But he didnt pass and did give me the thumbs up when we split in town.

What is our govenor at? On my '92 the tach turns yellow at 3200 ish.....does it actually have a governor that i can push it too and hold?

Yup, the pump will have a govenor.

If I'm not mistaken, if one of our IP's dont have a govenor spring they run away, correct?

Mine is governed to 3300rpm's under load, and 3500rpms free rev.

 

[FordGuy100]

The newer common rail cummins have turbo's that the exhaust side has theoretical housing sizes anywhere from 4cm^3 all the way to 26cm^3. 4cm^3 is very, very small, and would spool so fast lag wouldnt be a problem (only problem would be backpressure).

This is why VGT's turbo's are so cool. http://www.youtube.com/watch?v=S33IDPbQcck&feature=related

So how safe is it too push them close to that? I.e i normally dont run it much over 2500

Trust me the wait is worth it.

Thats goin in my sig.

Mine stops at 3300... I've gotten there plenty of times in shifting gears, never run the motor over 2500 for extended periods of time. Thats me personally tho...
