Well I loved my stock turbo and FP RED Here is my stock graph with red over layed... Both were with minimal tuning time. Basically start it up, a few pulls, and then straight to the track... Great results with the right parts and right tuner...

 

Mostwanted or Mike, can you guys put the two boost plots on a graph from those two dyno runs and post them up? Thank you. What was the parts combination on those two runs Brian?

 

OK. I'll bite. I bought one of those, (HKS BB turbo) and here is my reasoning why, or why I'm hoping it will help me out. My car is 100% street driven, with a kid seat in the back (sometimes 2). I have a 2L motor and head being built right now for it. I run e 85 and V7 on the stock ECU. The big problem I face is that I want to run the stock cat back, and even though I have it set up running SD currently, I like the OE airbox as well, not for legal reasons but for noise control and keeping NE. weather out of the engine.

I'm looking to make about 400 AWT as low an RPM as possible on the new HKS turbo and I could care less about peak HP as long as its strong till 6.5k. I have had a TME on there for the last 50k on the stock motor and I refuse to put anything on that spools slower. I'm hoping this thing will make more power on less boost and not give up too much spool on the TME.

Now don't ask me why I need 400 AWT to drive me and my kids around, but I can tell you that to open up the breathing on the stock/9/TME to the extent that it will crank out that power is going to **** of the cops, my neighbors, kids and the wife. I know, I have tried it.

Finally, it was 1800$ with cams and springs!

 

956307076, haha, yes you did bite! Just kidding. The build, to me makes no sense simply because you've got the car bottled up on both ends, the intake and exhaust side. I semi-understand the idea but of it all but for ME as a car builder it makes little sense because there is more power in those two mods than there is in the turbo upgrade(s) you've done. It's your car though and I sure hope it works out for you and stays quiet to keep everyone happy. Good luck with it.

 

MA. state legislation and the general burden of conforming to society I have seen people spend over 1800$ on crazy exhaust set ups with three mufflers etc to quiet down 35r's. Did I mention I got cams with the package too?

Of course at some level, yes it makes no sense but then again we all insist on messing with cars as well.

 

For me I looked at it like I could sell my BBK and Kelfords and break even to try something that looked like it will perform almost as good as my BBK did.

I know you and Mike aren't high on the CBRD turbo's and it appears you guys have gotten really good gains on the OEM turbo (better then I've seen almost anywhere) but what I can tell you is on my IX turbo setup I was making 385 to the ground (on E85) (DLL.....less on a Mustang/Dyno Dynamics more on a DJ) and after swapping to the BBK Full with the same tuner and changing nothing else I made 425.

All dyno's/tuners are different and I understand that but given my variables the BBK Full made a significant difference.

The reason I jumped on the HKS is because the numbers looked very BBKish (almost as good as the BBK-B coming out) and HTA Greenish but ball bearing (I have PM's from people who've had issues with journal bearing turbos that aren't using the OEM CHRA).

I figured worst case scenario I get BBK numbers but in a BB turbo....I can always sell it and go another direction. I have no doubt with this HKS and Owens in the UK offering BB upgrades to FP stock frame turbos that stock frame BB turbo's will eventually became a norm, but until then........

Lastly the reason I jumped on it is because I cost me basically nothing. I had to take my head off anyways (long story), so I decided to upgrade then. I sold my BBK for 1250, my Kelfords for 350 and my supertech setup for 300. I got the HKS turbo, springs and cams for 1850 and manley retainers for 150. I spent 100 dollars of my own money to do this.........Plus I anticipated that once more of these hit the market and the numbers start coming out and people really start pushing the limits of it the BBK Full's will start going up for sale and won't be worth as much.

Funny thing is I'm not EXTREMELY concerned with response. I am used to it though. I have a certain peak HP goal in mind though. If i can hit it then I'll be happy.......for now.

I have a itch to do a built BR motor and BR FF HTA turbo kit. That will be a few years from now

 

Is it counterproductive to run huge cams with a small turbo? if so, why? I am only worried about power, not spool or dd

 

I think ER has ran GSC S2's with stock frame turbos and had interesting results. You might need to search for the thread.

 

It is not counterproductive to run big cams with a small turbo, we do it all the time and the cars make great power.

I am not down on CBRD or the turbo's. The turbos are produced by Blouch and we use the Blouch Dominator on most of the EVOX's builds and I used the Blouch GT600r on our EVOX also.

 

Let me be more specific. the BBK series for Evo 1-9's.

 

Very inspiring results. I really don't see myself needing more than 400whp for what I need the car to do (street and autoX). At this level how much are the cams worth?

 

I personally like the idea of the HKS turbo for a couple reasons and it all revolves around altitude. Not all of us get that Ohio air that is like 10% denser than any other air you'll find in the rest of the America. We've had the altitude conversation before, but I don't care what you think, the engineering, math AND RESULTS is there to prove undoubtedly that a turbo up here chokes up and greatly limits the HP potential of the turbo.

Take that IX compressor flow rating of 42 pounds/min and multiply it by 0.85. That is where the IX chokes up at my altitude. 36 pound/min! Take that same 42 pounds/min and multiply it by 1.05 and that 44 pounds/min is about what you get in Ohio on a brisk fall day. Just going off 10 HP/lbm, that is 80 WHP difference in airflow potential!!!

The highest HP I have seen on the IX turbo in my area is 385 WHP (uncorrected) on E85 (actually, we only get E70). I've done everything I can to grab those last few HP on my car while still running 91 octane. Forward facing turbo inlet, tubular manifold, head work, ported manifold, tuned to the absolute edge, blah blah blah.

End results is 360 WHP on 91 octane.

The stock turbo on my car will not hold more than 19 psi at 7500. If you look at manifold pressure, that is the same as ~16.5 psi at sea level. 16.5 ****ING PSI! I've pulled the exhaust and ran without a filter just to make sure those weren’t choking anything up, it didn't make an ounce more boost.

I can pick up some more HP with things like the HTA cover and maybe a cam change, higher compression, alcohol, etc. But it isn't going to come from higher airflow (save for FP compressor cover). That extra HP is coming from improved efficiency and nothing more.

This is when something like the FP White comes in. It gets the compressor flow up to 47 pounds/min. Correct for altitude and it drops it to 40 pounds/min. Hum, that FP white still doesn't even perform as well as a stock IX turbo down in Ohio in September...

So, the white is still less powerful then a stock IX turbo at sea level. Ok, how do I get more power but maintain spool? Hum... HKS GT7460 I've heard is rated around 52 pounds/min and offers stock like spool… 52 pound/min corrected to 44 pounds per minute, HOLY **** I'm actually up to where a stock turbo in Ohio performs now...

Not all of us are blessed with air density that is, well...spectacular...record breaking...amazing...

Summary, the only reason you have pushed an IX turbo that far is because your local air conditions. I don’t say that meaning to start a fight. It is SOLELY THE TRUTH. Do I think you could come up here and make more HP and run faster on an IX turbo then me? Probably. Would it be ANY WHERE NEAR what you see in Ohio? **** NO!

I don't have a boost plot for this tune but I have one for my last tune that made 380whp on the same dyno and I can post that graph/boost plot if you would like me to. I also have a graph from what I made on a RRE's dynapak on the tune that I made 380whp with as well and I can post that up if you want me to also. IIRC Bryan told me the car was making 27psi right before 3300rpm on the power/tune above.

 

Another car requiring E85 to make 400whp on a Mustang. Dave your 93 octane results just don't seem normal. Hopefully more people will post up sheets so we can get an average.

 

He is on 10:1 compression too...so that will help with power for sure. However, typically it makes running straight 93 octane tough...but if you tune it carefully, the results can be as shown.

I really don't think he would make up these results, lol. What does he have to gain by that?

Awesome 93 octane stuff David!
