Yes please. I have the TS 7163 IWG on SR20. Interested in others results.

Cheers

It is on a single scroll manifold I think and stock camshafts, solid lifter conversion to head, will be on E85.

We don't care about peak power, how does it drive?

Only going off the info I had on hand at the time (an email that came through).  How does it drive? Can't comment on how it drives now but as it was said earlier, "un optimised" it was a significant improvement in every way compared to the -5's. That's been said a few times now though so it's going to be interesting to see how much it's improved again in its finished state.

Treadstoneperformance (TRE) you can weld 3" on the inside of theirs and 3.5" on the outside.

3" assembly:

Both 3 and 3.5" flange:

I would not waste my time going 3" again

Nah, exhaust is sorted and am getting 3.5" made, was wondering about the compressor outlet flange, if you hack the end off its a vband, but not all v bands are created equal, (eg one my fabricator has bulk sets of has rubber sealing rings), just trying I figure out what people have used with success.

Thats what Hypertune did on mine, Pete. 2.5 inch to 3 inch 90 degree elbow.

Careful...you will break down on the last lap of a race like Toyota at Le Mans when you use Wiggins clamps :)

 

Looks neat. A friend who has owned a few ex Gibson cars say that over time they can vibrate open so not a bad idea to just put a cable tie around them. Seems odd but i am not going to argue as mine are all hidden by diffuser etc and not accessible and be a head fark if they ever opened.

Nicks car just in.

-5's 424 rwkw at 24 psi 

8374 1.05 462 awkw at 24 psi.

Same setup, same engine. 3.0, 9.0:1 comp, 260 poncams. No graph yet.

Wind it up to 32 psi mate - should see 500-520kw :D

I'm gagging for those SR20 results. A fair few results on SR22DET or SR20VET or SR22VET.... but not much with a more 'simple' smaller cam, standard-ish SR20det setup. Would love to see what poncam, e85, t4 ts mani and EFR 7163 would look like (graph)

Ok here are some results.

SR20DET, forged bottom end, sold lifter conversion stock cams I think or maybe baby ones.
EFR 7163 IWG on old school manifold not sure if twin scroll, T4 twin scroll exhaust housing ( not sure of size)
E85 run in tune made 270rwkw @19 psi, 305rwkw@25 psi. Makes 16psi @3000 rpm and looks like it is a response monster.

I think the owner will get it back to shake it down before they lean on it anymore as it's a fresh motor.

Sounds good. Would love to know if you could confirm manifold and cams being used. Was expecting a LITTLE more if it's a T4 TS mani. SR20's do love a cam increase, so will hurt it alot if running stock cam.

 

Got a dyno sheet?

It was a manifold built 15 years ago so I doubt it is split pulse. No dyno sheet yet.

I also assume the ignition is very light on for this run in tune, also don't know how good the exhaust is as it's 15 years old (but has only done 5000 kms)

stock sr20, 260 procams, E85. TS T4 7163 IWG on fullrace mani and dump.

Boost issues.

Dropping boost on top? Mine was on the medium cannister. It's almost as if these things should ship with high boost cans factory. Was cool to see my car make 376 whp on 11 psi though!

Yeah been a bit of an ongoing stuff around. FR shipped the wrong high booster cannister for TS frame. So then got a turbosmart dual port locally. It wouldn't hold boost. So changed EBC to one which can have different duties at different rpm but apparently made no difference on the dyno. Pretty much I don't think tuner likes the turbo :blink:.

Yep. No way to keep boost high enough on top end without changing duty cycle throughout rpm. Mine is almost linear on duty cycle for rpms after it onsets.

    • You need the kit turbo taipan has shown you because that manifold ia designed have side feed injectors 
    • @johnnysr22 did you end up installing the little screen thingy and did it work ?>   
    • There is a LOT of stuff that can be done, it all depends on how much time and money you want to spend on doing in.  Not all ECUs will be able to do it, and the more control you need the more time and knowledge needs to be put into making it work.  If you're willing to spend the time and money and have the right hardware and skills involved there's a lot that can be done. 
    • I am impressed with all this level of adjustment. I didn't expect all this possibility
    • Correct.  In the case of the 500kw dyno plot I showed you the car actually runs two boost control solenoids for boost control and a 5psi wastegate spring.  It allows me to control how much boost pressure is applied to both sides of the wastegate valve at any point and fairly accurately control boost target as a result. I've tuned it so that it's able to target anywhere from 5psi to 25psi depending on what's needed.  The target tables I've set up in that car are Gear vs RPM, so every gear has potential for a different boost (and torque) curve.   First and second gear have quite low boost targets, third gear actually has different target boost all the way through the rpm range as it's a stock RB25 gearbox - the boost targets have been chosen to maintain a peak of 600nm (what the owner has set as the maximum torque he's happy with putting through the stock 3rd gear) but it carries that to the rev limiter.   The boost curve to achieve that is something of a ramp up, then hold, then ramp up again and the power curve looks more like a flat line haha.
