A little of dyno time
-
So since I moved to Ireland, i have been doing a little street tuning on some Hondas here since not very many people tune anything other than Apexi, and no one really does turbod Hondas. So this is an ITR that I street tuned back in October, and has been daily driven since then at 14 psi on 91 octane. It is a stock sleeved, built bottom end ITR engine, with a GT2871R. Today we got some dyno time to see how much it is making and do a little fine tuning since it had been running great anyways, really didn't have to do much tuning on the dyno, since we were already past our goal of 350 hp.
380 hp and 286 ft-lbs torque at the hubs (using a dynapack) on 14 psi.
I was very impressed with how much power this turbo made for pretty low boost, and how quick it spools. I will get some pics of the car up in a little bit when I have time to upload them.

good job, what turbine side is that on the 71r?
Also this pack dyno's read a bit higher correct?
sounds like all is going well over there.
-
I believe the owner said it was the .82 A/R housing. Dyna pack is going to read a bit higher because there is no loss for the weight of whees and resistance of tires, but Im not entirely sure how much and how it compares to other dynos. All the results that Full-Race puts out are from a dynapack (Locash Racing's) as well as all of the results from Jeff Evans Tuning.
And it is a Honda, what do you expect it to have for torque....

yup, dyna packs have no load bearing on the rollers. There are some dyno jets that you put load on, and MD's are somewhat adjustable as far as how much load is put on.
Sounds like you are having fun, what were you tuning with? You should throw up a dynosheet, possibly some logs from the tune you did.

Zac, Dynapacks are loaded. We did some steady state tuning and then you can adjust the ramp up rate, and there are no rollers on it since it is a hub dyno. Most dynojets are not loaded, and all mustang dynos are loaded.
It was tuned on Hondata S300. I did post the dynosheet on top.

Zac = dyno guru now..........
nice work trevor! P.S. Cant wait to c ya agian

Oh, I didnt see the sheet (govt filter). Dyna packs are goofy.
there is one dyno jet that allow for load bearing. i dont recall the model number, but it one that my car was on a while ago.
I know that MD's are loaded, i just said the amount of load is adjustable.
-
I am perty sure from what i have read that with a dyna pack you loose just a set amount of hp regardless of the amount of hp being produced....... instead of loosing a % of the hp on like a dyno jet
but yeah a typical higher reading on the dyna pack..... IMO a better dyno
-
Yeah, i have been on a few different dynos, but haven't done any tuning on the dyno, and the dynapack was great for it. Steady state mapping is SO much easier and quicker than street tuning.
And I can't wait to see you either Travy

You dont loose HP on a dyon that reads lower.
In all reality, numbers dont mean much...if anything at all.

I too like to see the comparisons from dyno to dyno. I like the MD's

there aren't any inertial losses on lets say a dyno jet huh :icon_scratch:Why would there be? they are both inertia type dyno's.
assuming thats what you mean.

he is saying it takes power to spin the huge rollers, unlike the small hubs on the pack dynos.
correct z brown?
