2001 24v horespower increase

[baccoman]

I am wondering what would be the most cost effective add on to my 24valve that gave me a noticable increase in horsepower, and yet was affordable, and didnt require automatic transmission upgrades?? any comments appreciated

You could do a "plug in type" (Ez or VA) or go with injectors. Adding one or the other would be ok for the transmission stock. Add both of them and you will need to look into the transmission issue.

If you spend some time looking for info on this topic you will find more than you care to know.

Happy BOMBing.

Injectors are the best bang for the buck. Check out www.dieseldynamics.com for more details. #ad

I think the best bang for the buck here does not matter... he doesn't want transmission upgrades, so he is limited in the amount of power he can add.

For autos, it seems the best upgrade to do is 275 injectors (dynoed at about 45 HP) or the VA at 42HP, or the EZ(or DD box).

As far as "bang for the buck", how can you beat 275 injectors? Do the simple math. Less than 300 dollars, for about 45 HP.

DD3s give 100hp, cost 1000 dollars(boost module required) $10. 00 per HP.
275s give 45HP, cost 300 dollars. $7. 00 per HP.

Rob you forgot about the DD1's. Stealth at no xta cost,better performance than the 30 hp, 275 warranty voiding Boshes, and 50 hp. @ $10/hp less 20% TDR discount #ad

Jnutter... OOPS! Forgot about the 20 percent discount for TDR members...

But, the 275 injectors have been dynoed on autos at 50HP, same as the DD1s. Its all in whose dyno you want to go by. Auto transmission shows a better increase for the 275s, but even an ETH was recently dynoed with a 42HP gain on 275 injectors.

The stealth thing is a factor, but is it worth it? Everyone has to make their own judgements on that!

 

[Evan A. Beck]

Rob, don't forget the at some trucks see no HP gain with the 275's. Remember James' truck? Gained about 100 lbs of torque, but no HP.

Baccoman, check out the 275 injector comparison on DD's website. It gives an accurate side-by-side comparison of what the 275's are capable of.

Evan... I really hope you don't believe that is true! Just like many of the other runs that day... do you believe that the guy that BD installed 275s for LOST HP? Or the guy with the propane, PE and EZ only has 330HP?

I still maintain that dynos are a good measure, but they can have error, too. Just like the chart I posted a while back, showing a friend's 500+HP, when we all know it is not that high... but, the dyno says so!

 

[NDRamrod]

How can you put injectors in and still get boost? yes you can plug the waste gate. But the computer shuts the truck down over 20 psi???

All I am saying is the gains with just 275 injectors are very inconsistent. Some guys get 40, some get 10. The readings are all over the place. The reason being, is the injectors are not a balanced, matched set. You are getting 6 random Bosch injectors.

45 HP is an awfully big gain with just 275's. I know yours didn't feel like it gained 45 HP when we did injectors. Combined with a VA or fueling box, the injectors give a pretty healthy gain, but by themselves, 25-30 HP is typical.

It would have been interesting to see what James' reading had been if they had timed the truck for parasitics. Seems the readings are far more accurate when they do that. They did that both times I dynoed my truck up at BD. The second dyno trip I spent about 40 mins on the dyno. 3 runs, plus parasitic timing.

Here's a dyno chart comparing injectors on a '99. Note the 30 HP gain with 275's. Don't get me wrong, 275's are a great addition to the truck, and they really show their potential in conjunction with a box of some sort. But by themselves, the gains are just too inconsistent to say you will get a gain of 45 HP.

I would agree that the matched set of injectors do better... one of the reasons I changed to DD injectors.

The one point in my thoughts is: Is it the 275 injectors that make the inconsistant dynos? Or is it the dynos that make the inconsistant results? I believe it is both. I have seen way too many dyno runs that were way off. I have even posted a few here.
James did not have the luxury of spending that amount of time on the dyno... and the dyno for these guys was an average weight, etc. This is not a fair comparison. Also, with his topper and accessories, he is probably as heavy as my dually!
One thing we should all remember... Dyno Days is a blast, but the dyno results can not be totally accurate when there is 100 guys waiting to dyno, and they are rushed in and out like that.

You are right, tho, the difference in the smoothness of idle has convinced me that if you go with matched sets of injectors, you will always be better off. I have seen this in several different trucks now, including my own!

I can tell you a box like an EZ will be much more noticable driving (seat of the pants) than was my injector change. !!!!

Dyno Days is a blast, but accuracy is a concern. Lots of variables to take into account, and due to time constraints, some have to be overlooked. It was nice having it correctly dynoed, though.

Maybe we can do it right at the NW Dyno Day that you and Vaughn are thinking of, Rob?

Remember that the type of dyno used is just as important. I understand that the BD dyno is a load type, not the inertial type like DD uses. The inertials are a lot more repeatable and consistent from dyno to dyno, since operator error isn't involved.

Also, RV injectors seem to give 25-30hp on an ETC truck, roughly half of what the DD1's do. On an ETH truck, they do 40-45hp, or again about 25hp less than the DD1's.
