That's were I can only hope my 3076 will end up on ca 91! #hopeful #wishful thinking #gojamesm

I've also seen Crawford's car dyno on the same dynapack my stock car put down 159 on... I don't pay much attention to numbers though...There's 4 street class hondas sitting in the parking lot here right now that all run from 8.0 to 9.0 in the 1/4 mile and i dont' think a single one of them could show you a dyno of the power they make at the track.

Regarding my issues, I will add that it put me in a difficult position.

I went to JDL for their IP, their experience, the way I had seen them handle issues with the early design headers.

But I'm not a fabricator, a mechanic or a tuner; I'm an enthusiast. I may be say 60% of a mechanic, and I've done things like install turbo kits before. But that was on beater 10year old cars, not a new car. I don't want 60% jobs done on my car, I'd rather dip into my pocket and pay for the best parts and best people I can find. (To a point)

I didn't notice these issues, my mechanic did. Now he knows I'm particular, which was why he mentioned it. I then went to the fabricator I use most of the time, and he was hesitant to say anything, citing that he didn't want to be that guy critiquing another's work. But after some prodding he gave in.

And in case his opinion was biased, (and still thinking to myself that JDL from what I can tell have a better name for quality than he does) I took the kit to another fabricator - Racefab. These guys send almost 90% of their work overseas, basically because no one locally wants to pay for their quality level. I've used them only a few times, once on the gt86 for all my rear suspension arms, $3500 worth. He had the same opinions as Simon (first fabricator)

I then took it to nzefi, the local tuner shop, they said the same thing. I then sent shots I took to another tuner I respect, he said the same thing.

Whether the flat flanges will leak or not, and whether the linishing / belt sander on these flanges was necessary, I can't say. I have JDL and a few here saying they're fine, and many others saying no.

The mismatched size flanges are the particular thing I don't like. If it should work that's fine, but I'd MUCH rather have been given the option to have the matching tial one on there. I also am not even sure how you would do up the vband when the sizes are mismatched, do you have to centre it by eye as you are tightening? Anyway doesn't matter.

I also understand the justification behind using these flat flanges, that it gives some slight play to ensure it fits most people's cars.

The point I'm trying to make, is who do I listen to?

The mismatched flanges, I'm definitely not happy with, so will be putting the tial one on there. The downpipe to overpipe flanges, again I can see the reason why they're flat, but I'm going to get them replaced for my own piece of mind.

Take my comments / reviews for what they are. An honest expression for others to learn from and make their own decisions from. I didn't ask about these flanges prior to being sent the kit, so obviously I didn't ask or know indeed what I wanted.

Heck, I can even understand the business decisions Jdl have to make with these types of things. The market will spend $4000 on Avo type garbage, and quibble over spending a little bit more for quality. So they probably have have to watch just how much that $ difference is. (If that indeed was a consideration JDL were/are making. Generic/flat flanges being slightly cheaper, using them on the downpipe so it matches a few turbos, not just the specific one chosen to save on production time by being able to make the dp's in runs)

Realistically it hasn't put me out. Kit was going on till next week anyway. The locating type vbands only cost me $45 a set. The tial male flame to the turbine I couldn't find one in the country so had to borrow one off a friend that had one sitting around; that I'll need to replace. (Any tips on where to get that..?) And it's probably going to cost me a box of beers to have the flanges changed.

Overall i'm still happy. The rest of the kit seems great so far. And it's probably pretty rich for me to complain about the overpipe anyway, as I was given that for next to nothing as Jesse wanted confirmation that their 3" OP fits rhd.

I just want my 250ft/lbs at 3500rpm now dammit! Lol

The Dynapack can display crank HP or WHP. I think that plot may be showing both with the higher lines being the calculated crank HP? The other thing to watch out for is the "TCF" value which is a correction factor and multiplies the output. Most dyno shops use a 1.00 as the TCF otherwise it inflates the values. So if you use a 1.0 TCF with the red line values you are looking at 288/222 which is also not out of line. Guess we'll have to wait and find out.

Crawford has a crank HP correction. Non crank corrected that was SAE corrected was ~320-330WHP on 8.5PSI with 11:1 CR and a stock midpipe. The tune was fairly conservative and we were doing a lot of toying around in maps and never sat down to try to really push the car. We did some play on E85 but I actually ran out of time before finishing up. One of my last pulls was iirc 375 TQ (i forget if it was WTQ or BTQ i have to check!) and still rising but hit a load limit in ecutek. I didn't get to finish that but was expecting ~ 480-540 BHP @ 14-16PSI on E85 based off the graph we were seeing.

Regardless of everything 8.5PSI making 320+WHP on 91 octane seems pretty damn stout when you consider I was using a stock mid pipe! I'll be pushing the car a bit more tomorrow with street tuning on pump gas again and then moving back to E85 and fixing the load limit issues. I am sure it won't take me too long to get some higher HP dynos posted. =)

Are you sure it was load limit and not injection volume limit? Remember my issue...

It is your issue I just didn't wait to type a full explanation as most won't understand.

Gotcha!! Let me or @jamesm know if you need any help!

[jamesm]

I'll be posting a screencast that covers the injection limit very soon. Already done... just gotta send it to youtube.

Well done mate, brilliant numbers already and lots of promise for more to come ......

Another kit was on the dyno yesterday out in San Diego. GTX2863 equipped UEL kit. Hopefully we'll have some dyno sheets and sound clips soon.

Cleanest kit was an understatement. Not to mention it made the most power out of all the kits we've tuned on that dyno, and one of the smallest if not the smallest turbo! Looking forward to working something out on that twin scroll kit of yours

I'll be out there next Friday to have Bill work his magic as well

[Shit Luck]

that setup looks damn near identical to what I have going on as soon as they ship.
