diesel hot rod association.

 

oh, i think maybe ive heard of them. are they a pulling and drag racing association.?

 

:pc: wow this reminds me of some other threads doesn't it possom. You sure your twin aint coming out to play tonight?

 

If you race in a DHRA class then just say so. Thats not the issue being discussed in this thread. To get back on topic, the issue is that the statement has been made that a daily street driver cant run a low 1.6 time and thats not the truth. It doesnt matter what make of truck it is that does it I know several that can and theres plenty of documentation and witness that shows that. SO, lets get back to friendly discussion about the topic and everyone have a good time doing it.

 

Speaking of twins, my friend bobo that just recently stopped in here at DB is one of the foremost DMax twin tuners in the bus. I think he'll be more than happy to verify the 60ft times of his truck and the many others that he has tuned. Yes, you too can run a 1.6 if your bank account can handle it.

 

I think what Possum is getting at is that it is hard to believe when Jimmy was pulling off those numbers with a dedicated drag truck.

 

Gentlemen, we are an ALL brand diesel truck site - and will not tolerate brand bashing. There is no reason to deviate from a friendly tone. No one is saying that you cant disagree, but please stay courteous. Thanks and we appreciate it.

 

Yeah, I know it doesnt make a lot of sense. Me and a couple of other guys are in the process of slowly putting together a team with a single cab full race LBZ powered truck. By my calculations and many years of racing a stripped race truck producing close to 1000hp should be able to cut 1.5's but they're not. Why? Diesel racing is still young and right now all the foundations are being layed and technology being developed. There are two things that I THINK that causes a street driven daily driver to cut 1.6 next to a full race truck. Tuning is as huge factor for one. David Lott and Nate Dwyer are both personal friends of mine. David had the worlds fastest PStroke for a couple of years. Why is it that he could never break a 1.6 60 time but street trucks could do it right there with him? I think tuning is a partial factor. It SEEMS that you just cant get a diesel to produce torque fast enough no matter what you do. There is a give and take and we just havent got the complete understanding of tuning a modern turbo diesel YET. Another theory I have is that the more we try to develope full race trucks the more we suffer on the bottom end to be able to run the low quarter times and high trap speeds that are being achieved. I can say that on my truck it fell on its face shifting from 4th to 5th at anything lower than 3/4 throttle once I went straight pipe. I needed to lower egt's but I suffer on streetability. I'm just throwing out my personal theories and yes, I'm an Engineer so I approach this from a law of physics stand point. I've been racing for almost 30 years and some things in diesel racing has me baffled. BUT, there are a lot of people out there right now that are figuring it out. Just gonna take time. We just recently gained technology in the DMax community that will allow our engines to survive 1000hp + and it took 7 years to get that done. I cant explain why things are the way they are in the sport but I dobnt trhink its going to be much longer before we get these issues sorted out. Possum, I never meant any disrespect for your work and hope that you break the 1.6 mark, but that doesnt change the fact that a well equipped street truck can run a 1.6 60 ft time. Why? I still dont know.

 

I was joking about the chevy comment. I dont think its cause we cant get the torque at the low end it could be weight or the fact we tend to spin to much on the line.

No andy i save my twin for kydtr when it needs to do some adjusting. And this is a friendly debate but like i said i will pay more attention this weekend at bowlinggreen

 

Ok, but just as long as you know that ya gotta be smarter to tune 8 cylinders than 6. j/k
Actually, now that you mentioned it, I was having a conversation with someone a few weeks ago that also mentioned having traction issues at the line because of not having enough weight and the power coming on too quick. The discussion ended with doing some experimenting with the fuel and boost tables to retard the turbo for a moment off the line and then let it come on full boost just before the 60ft.
