08 Duramax Vs 07 Titan

Titanequipped · 04-16-2008, 03:27 PM

O.K. Guys here's the story. I have an 07 C.C. SE 4X4 with 325/60/18 Toyo Tires, Injen intake, Magnaflow exhaust and 2 degree timing. The Duramax is a 07.5 (LMM New Body Style) 2wd 2500 all stock except the muffler is cut off and a S&B intake, NO TUNE! I know this, because this is my brothers truck and I've been wanting to race him and I finally got him to give in. Rolling start at about 30 mph I give him a jump then bam I'm a good 1 truck ahead of him, I thought I was just faster, turns out as soon as he floored it, his truck downshifted twice thus my jump. So we start from a dead stop, I give him the jump and bam there he goes???

We were side by side I could not pull nor could he???? I thought I would definitly blow by him. NOT THE CASE! He is soon going to be adding a mild programer with wider tires. There's no way my truck can keep up after this. What else can I do for performance that will help??? Cams are not available for the 07 and talking with uprev, it won't do a hole lot for the 4X4 any suggestions... He agreed on the race as long as I raced him after the programmer is installed.... What do you guys think, I need a SC or a shot of N02????

a stock new dmax runs 15's in the quarter just like your titans. that truck will run 13's with a tune without a tranny for awhile...youve got a lot of work to do....hes got 10 mins of programming to do...

my dmax i traded in ran 13.10's as a daily driver with a tranny and a tune...the new ones make more power and with the same hot tune are in the 12's...

Titanequipped · 04-16-2008, 09:10 PM

Yeah that's what I thought. He's only going to put a mild tune he said, somewhere around 60-70 hp and that's it. I think that would put him right past me. I just say a post here with a DMax running 10second wow that's fast!!!

You better tell him to take it easy on that tune or he'll be buying a new transmission VERY quickly. I ran a tune that was around that and could feel the transmission slipping badly.

What are you running now. He's got the allison trans in it. He talked about getting more plates put in the tranny, but was told with a mild tune like 60-70 hp he wouldn't need it. He want's it for towing and when some little ricer comes rolling around bam black smoke in the face...

he wont need a tranny for 60-70...some of the newer transmissions are holding up to around 450hp but they wont do it for long.... as i said there are some newer dmax trucks in the 12's just with a tune

the 10 second truck has lots of money in it you dont need to worry about that one...it is street legal though and PULLS his vette to the track with it...its faster than his vette right now.

The DMax has a power adder and you are NA, with that being said, if I were you I'd get a power adder, my choice would be STS Turbo.

A friend of mine has a '02 DMax. He replaced the factory air filter with a K&N, replaced factory muffler with a Bullet Muffler, has a Bully Dog programmer on highest HP setting, and a Banks BigHead waste gate. He had zero trans problems. Then he install propane, and after using that a while the trans started going into limp mode in 4th gear on the allison trans (if I remember right). Needless to say he got rid of the propane and the trans is still working good. Once he completes the updates on his race car his is going to put a converter and rebuild the trans on the DMax.

I've ran him on the street a few times and although his truck is 1 sec and 10mph faster in the 1/4 mile, I can still beat him 0-80mph because of the traction problems he has. So try to race your brother right after he gets the programmer, if he is not used of the new power and has traction issues, you may just pull him off the line enough to where he can't run you down by the end of the 1/4 mile.

why does it always come down to the turbo? if its a factory turbo then its factory its not something added....if the titan came with a sc then it came with an sc...diesels do not come WITHOUT a turbo....

also, the dmax stock air filter is good for 500rwhp, the aftermarket just adds turbo whistle....

I guess I wasn't clear.....what I posted had nothing to do with the "but he as a turbo excuse". Titanequipped asked what he should do to hang with or out run the dmax and I just suggested he go with a power adder. I said that because a programmer for the dmax would pick up approx 100hp, so I would think Titanequipped would need to pick up approx 100hp also (power adder).

Diesels today may be all turbo, but not very long ago many diesel engines came WITHOUT a turbo.

The DMax with the K&N doesn't sound any different that it did with the stock filter. Also, I've talked to a few turbo diesel owners at the track and asked them why some stock turbo diesels whistle more than others and everyone I spoke to said it was from running either no exhaust or just a straight pipe.

didnt mean to jump on you but the way you said he has a power and you are NA i thought you were talking turbo...

100 hp on a diesel is 200 ftlbs of torque. not so on a gasser so even if he did pick up 100 horses, if the diesel hooks hes gonna leave titanequipped sitting there.

exhaust does play a big factor in the turbo whistle but believe me, unless youre going above 500 hp the stock intake flows the same and filters better...

Since my brother cut his muffler out on WOT his turbo whistles loud. I helped him put a S&B, but not very good quality or should I say fitmit. With those 2 things done, not much performance gain he can feel. He's waiting to get new wheels with small lift and a programmer. Urghhhhh

I'll cheat and jump on it and once he starts to catch up I'll let off... HEHE

yeah the new stuff is pretty loud but cutting the exhaust off helps a lot. he'll be hard to catch with a programmer...

IF he gets the right programmer. For instance....a friend of mine and his dad both have 02 DMax with the same mods except for programmer. My friend has a bully dog programmer and his dad has superchips. My friend runs away from his dad in the 1/4. The only other difference in the 2 trucks is the Dad's truck has approx 3 inch taller tire.

youre comparing diesel to diesel which is fair.... the gas motor to diesel with tuner is not...

Titanequipped · 05-10-2008, 10:05 AM

Seems you two are the Diesel guys here.... Anywho I'd thought I give you an update. My truck has been in the shop the last 3 weeks getting some stereo and alarm stuff put in and changed so I've been driving the Chevy. Wow, it's a cool truck. I love how you can hear the turbo an feel it when it kicks in. The truck is smooth and has lots of power, it's very noticable when climbing long grades. I have to push the pedal very little to fly up the grades. What I don't like is because this thing is a 2500HD, it drives like a 2500HD. The Titan is a much better ride, especially since I have DR's in front and rear. I know just like you can't compare a gas to diesel, you can't compare 1/2 to 3/4 ton either. Other than that, I really really like the 3/4 ton diesel... Oh and BTW driving on the highway in the diesel has yielded 20mpg vs 15 on my Titan. Although diesel is at 4.59 a gallon urgh.....
