Thinking about a dyno run pre/post DT headers

[lexi4darin]

Performance gains are a secondary benefit here. The real benefit is replacing a cracked or soon-to-be-cracked manifold, and upgrading to a better design that won't crack.

If you've got a cracked manifold the benefits might be more significant than you think. Honestly, it's the only thing that really explains why the DT's headers tested so much higher on the dyno than one would normally expect from a header.

It's what also gives credence to doing a couple of tests.

I've sent PMs to those who have expressed interest in this project

Payment sent! Thanks for putting this together Rob.

Payment will be sent later tomorrow. Sorry for the delay. for those of you who volunteered lets get this going so we can get the results. DT headers are next on my list and would like to see some hard data

I am in for $10. Someone let me know where to pay.

I agree with this completely. The number one benefit to me is my world-class, high dollar off road vehicle NOT sound like a hooptie anymore !

But I am interested enough to drop $10 knowing for sure about hp gains.

My headers are in the box in my garage waiting on me to get some time to put them on.

suggestion: Rob just post up your paypal email.. then new folks who are interested can just send you some dough, and spare you the whole PM exercise? Come back and delete your email later if you want..

How close are you?

Nakman, this is from Red's post on the group buy thread. Also, thanks for the contributions. I also made a second one after seeing your donation size.

"Well we should know the final result in two weeks. Stock run will be in a week followed by header install and then final dyno."

 

[2000UZJ]

My contribution is coming tonight Rob. Sorry for the delay

 

[RobRed]

PM's sent. First post updated with contributors.

Nakman I dont want to spam the general thread with my PayPal info. I'm not sure how sensitive the forum is to such things. If we get 5 more ppl we met our initial 200. If we get more than the 200 that will go toward dynoing Darins LX.

After lengthy discussions I would consider a second data point (Same Dyno, Same day) to be valuable and thus we decided to do an inital dyno on his rig as well. If the two are close then no statisical difference... if not we will do an after dyno on his as well. He committed to paying for it but if we can offset the expense as a group I think it's worthwhile to have two. As OregonLC pointed out they are essentially the same car so the initial runs should be within a few percent.

I promise you, the final report will be extensive in terms of disclosing all the factors we can think of so no question is unanswered.

2000UZJ totally fine. This is all volunteer.

Any deck plate mods in these runs? I may have to seal mine up after I see the results. I am just thinking more out needs more air in. Also, based on the pressure drop at WOT that the tundra solution guy experienced.

Thanks again!

didn't we already get dyno results on this from tarmacblack?

 

[uzj100]

I thought it was deck plate with no headers.

 

[RobRed]

Both my LC and Darin's LX are stock configuration. We will be providing detailed reports including age of components related etc.

Ok, great. Money sent via gift.
