Dynoed At 9 Pounds Of Boost

[turbonatormr2]

I am going to re-tune my car perrty soon on 100 octane. So I took my car to get dynoed with no boost just the wastegate at 9 pounds and this is what my car made. I also had an exhaust leak on the exhuast manifold. At the dyno we found out that one of the 4 bolts that hold to the exhaust manifold and I was leaking boost.

This is what I got.

Wow, very impressive... nice job!

Yeah! the guy said If I did not have that exhaust leak I should make around 315 Whp on 9 pound of boost. I'm in the process of fixing the exhaust leak. Cant wait till I dyno it at 22-24 pound on 100 octane.

What kind of turbo are you using?

[JekylandHyde]

What turbo that makes 300+ at only 9 psi can be run at only 9 psi?!
The least amount of boost I could run on my T3T4 and my GT35R was 13 psi (even with an 11 psi spring).

I assume you are using a pretty big turbo since you are hitting 200 rwtq so late.

Your A/F looks great What are you tuning with?

Looks like you are using the stock cams - correct?

I suspect revving all the way to 8500 rpms sounds nice
My new engine will rev that high, but I think shifting accurately above 7500 rpms will be a chore.

I am using the following Turbo.

Turbo
Garrett Hybird GT30 dual ball bearing turbo center section TS04(T58) compressor housing, T3 (.82 a/r) exhaust turbine housing with 3inch round outlet. Custom 3 inch down pipe with a tail 40mm waste gate with .9 bar spring Waste gate down pipe that dumps to air

As far as the tubo goes look at the previous post and I listed what kind of turbo it is.

What do you mean by tunning with?. Do you mean octane, or what kind of dyno I am using or what kind of EMS am I using.

Here it is. Octane 91 octane
EMS (Nemesis)
Dyno machine I will have to ask.

No my cams are as follows
272 Intake HKS
264 Exhaust HKS

Acutually it Revs up to 9000 RPMS but I just have it set at 8500 RPMS.

That turbo is some $$$$$$, nice job again! I have a GT28R on my ride, but still have to tune it to 20psi...

Do you happen to have any pictures?

edit: or Video?????

Okay, things are making sense now

You were NOT running 9 psi. Your .9 bar spring will give you at least 13 psi.
The size of your A/R (.82) explains the lateness in hitting 200 rwtq.

If you get your cams degreed, you will drastically change the rate of torque growth.
Look at my graph:

red is stock cams (looks like your growth rate)
blue is degreed 272int and 264 exh:
Look at that growth from 4K - 5K with the degreed cams!
I suspect your cams are just installed as per HKS's specs.

I was asking about EMS choice. Nemesis is a good one

Anyway, nice results.

Yes I have a .9 spring bar but since I had a really bad exhuast boost leak the guy who dynoned it said the car was only making 9 pounds of boost and not acheving the wastegate potential and they said that it only registeted to 9 pound of boost. They were really impressed witht he car.

Also the car was dyno and tune by Ricy-B before the exhaust leak. I took it to they dyno to see why my car felt so slow and wanted to know what it really made on the wastgate only. this was one pull only. They found the bad leak was coming from a missing bolt from the exhaust manifold. I was surprised that it made that much on 9 pounds of boost becasue of the leak. The people who dynoed it said "wow" who tuned this car? This thing is tuned to perfection except for the leak.

Here is the previous dyno chart. This one was done on 14 pounds of boost and 91 octane no exhaust leaks. But you are right I probably need to adjust the cams. Also hyde what would you recomend for my cams? becasue of the staggred set up.

turbonator (what's your name man? ), I am assuming the exhaust leak is what caused your torque to come on late. If you look at the other dyno you posted, you hit 200 ft lbs at about 4400 rpms or so (I hit it at about 4300), that is what I would expect. In your "new' graph, you are in the high 4's and that seems real late.

Did Ricky wrench on your car? I would think he would have degreed your cams.
I do not have the numbers off hand on what they should be degreed at, but Ricky would know.

The exhaust leak did cause the torque to come late. and caused it to only boost to 9 pounds on the .9 spirng wastegate was not going to it's potential. The cams do need to be adjusted and I have not address that issue yet. Ricky-B is the greatest and has not had time to degree my cams yet but that is next on the list. The reason why I asked you is because I wanted to know what degree you had them at to do a comparason with mine and yes the fist dyno garaph was at 9 pounds of boost only to much boost leakage. The motor was built my Chris-K
