I'm happy with my t-78... I saved a grand over your kkk kit.. enough to by me a haltech.. so a t78 kit plus haltech for the same price as your kkk kit... hahah more than happy... But you do have a nice car though... I thought you were selling it.. what happened?

Thanks. I don't know why people are getting their panties in a bunch. Its not like Im selling the KKK kits out of my living room. I just thought I'd convey my experiences with it. Far be it from me to tell anyone what to buy.
As far as my car,...lol....I kissed the wife's *** MUCHO and she let me keep it....

Don't "Hate the Player, hate the game".........meaning don't be jealous cause ya got junk! Dave at KDR said my turbo made more power at 10psi then any other he has dynoed.
Peace,
Ernie




I think Dave told you that so he can make you feel better since, your motor did blow again.

Correction Boy Genius, Dave blew my motor again. Those days are over as I've got the tuning issue's in the bag. IF ya don't believe me, maybe we can meet at a dragstrip and you can find out for yourself.........whats wrong, cat got your tongue???? Thought so........If ya can't hang with the big boys, go stand with your sister and play Barbie.

Exclamation

Wow, this thread is too funny. It never seems to amaze me what people write on this forum. This can easily be cleared up by having the facts, however, there will still be people out there who are too ignorant to understand the situation.

1. Yes, I was there when Ernie's FD was put on the dyno. I was there with my brother to pick up my FD that day. I had to wait a few hours for Dave to finish working on Ernie's FD so Dave could tune the Blitz unit on my FD.

2. There was absolutely no NOS or nitrous used at all. Hmm...Jason I'm actually surprised that you would even say something.

3. I was there to witness the dyno runs. Also, Kim, Dave, Gaab, and my brother were all watching the dyno runs too. Unfortunately the engine failed and everyone was extremely quiet and upset. How could you not feel bad for the guy?

4. Ernie's FD pulled that hp and his car spools much quicker than most turbos out there on the market.

We live in this world where there exist people that are jealous and ignorant. I'm not saying that everyone on this forum is like this, however, we do have some people. It's impossible to have so many people on this forum that are all open minded.

Wow, this is comedy. I was contemplating going KKK too but the price just wasn't attractive enough to push me over the edge. I went with the T78 and had money left over for a Haltech. To be honest the lag on the T78 is unbearable.

Nice post.

I did some analysis many moons ago when I was deciding on a single turbo. I plotted dyno graphs I got off the forum. Yes, I know many will not agree. Yes, I know a T78 can be tweaked to do better. But, this is what I had to work with when I made my decision.
I went with the T04e for the nice streetable power curve. Maybe I'm right and maybe I'm wrong. But that is what made up my mind, real-world data I had at the time. That was a year ago.

What's the biggest turbo you can get for a FC?

Why I Choose T04e Over T04s

If you look at the previous dyno charts I posted it was between these two kits. That was the choice in the group buy I started last year. I loaded the dyno graphs of the T04S(470rwhp peak) and T04E(410rwhp peak) from the graph into cartest2000 and did a drag simulation. Due to the great low end power curve the T04E kit won the drag race. Not by much. But I wanted streetable power and it won hands down. If I had to race to 150mph the T04S would have won. You can tell that by the drag race. See the pic.

I've got a question for you guys......is everyone comparing apples to apples? Is everyone's car the same? Are we all running the same setup?

If a person has a T78 and can tune really good.....isn't it possible to cut the lag down compared to another who just bolts the kit on? I mean there are a bunch of variables that affect lag right? It all depends on what your setup is designed for. If your going for all out power then how the hell can you beat the T78 or T88? It just comes down to tuning. Just add some timing and play with the fuel.....make sure you have a nice manifold design so it gets good flow to the wastegate. Is the wastegate directed back into the downpipe? At the right angle......downpipe size? Are your intercooler pipes too big? Is your intercooler too big for your setup? Boost controller plays a big role in lag......the list goes on.

I know turbo's vary in efficiency.......but when your comparing a couple of the greats.....i think it might come down to the individual.

I hope i'm not too out of line.......if this sounds stupid please tell me. I'd like to know if i'm right or wrong in my opinions.

You are exactly right in my book, tuning is the key, that's why some blow their engines trying to get it right and others get it right. Too many of our beloved cars are improperly tuned. Spent tons of $$ and not tune it and you waste your money. Tune it wrong and you either don't have optimum or you blow your motor. That's why I added water injection to my mods over one year ago. Lately Rice Racing has verified my decision with his experience with it. I'm on my last step of getting my car back. I have Dave at KDR doing the final stages of setting up my Aquamist 3d mapping water injection system. Then dyno tuning to whatever boost he need to get 425rwhp. This is the max rwhp that Rice racing and LaBreck said I can effectively use on the street. I will not be at the strip. Rice Racing will be assisting Dave with the programming of water and tuning water at high boost(over16psi). GMONSEN is assisting as well.

I might be an old hick from MN, but I know who to get involved to get it right.

If they pull it off, Kudos to KDR, LaBreck, GMONSEN and Rice Racing.

It certaintly was not me. I'm a hick from MN.

Of course Kevin Wyum is about 15 miles from where I live, so I guess, we are not all hicks in MN.

Had to throw that in.

470 * 1.1 * 1.18 = 610bhp.

Welp, since there's a pointer to this thread from the big list, I might as well put in my 2&#162.

*ErnieT's dyno run shows what a properly tuned Haltech can do with a big turbo.&nbsp It's on the high side, but it's within realm of what a properly tuned stand-alone EMS can do.

*I think one of the BIG difference that zayrx7's set-up has is the PFS SMIC.&nbsp I think this IC is too small for this application.

*LUV94RX7 had posted a pic of an Excel graph of a bunch of turbos, but I don't know if this was averages or he just picked them at "random" due to convenience.&nbsp The Mitsubishi turbos should be pretty similar (GReddy does have turbine A/R options if you know where to look), but I put money the Garrett turbos all didn't run the same (turbine) A/R with the same turbo exhaust manifold with the same (type of) engine porting.&nbsp This makes that comparison almost completely unusable.&nbsp silvr94r2 makes a good point that different levels of tuning can drastically swing the numbers.&nbsp Interestingly enough, the graph is consistent with what I've seen with the listed turbos:&nbsp Mitsubishi turbos are not efficient (down low) versus the Garrett turbos.&nbsp The T04S04 is not as efficient (down low) versus the T04B/TO4E (i.e. 60-1).

Yep, that is all I had at the time to go by.

Not saying your numbers are not possible, but I think the run may have started out 10psi, but the boost continued to climb some during the run. If you look at your torque curve you can see this. Your torque should peak and start to taper down if the boost level is stable, yours just climbs. Almost the same with the HP curve. But if that run really was only 10 psi I'm impressed. As far as t-78 not being any good, I'll have to disagree, I've made 570+rwhp with that turbo. When you make that with your KKK I'll be sold and switch over Ernie are you going to the battle of the imports Saturday?

i guess, i'm getting a T04E then.

Most of my driving in the city is done below 4k. Just cruising the canyons same.

But I want to make at LEAST 400rwhp. I know that is a little difficult with the large 18" wheels and a t04e though.

A smaller sized turbine housing on a 60-1 can take you there with the right porting. You would get good boost responce and your goal of HP
