M35 Turbo Upgrade.

[Intense m35]

The inlet track to the turbine is opened up all the way around. It even injects air under the turbine by about 40% Do you think this is why I have 20psi at 4700rpm and when running 25psi it goes from 25 at 4850 to 18psi at 6500..

Yes this is partially why I think you have lag issues, it is what's referred to as exhaust gas interference. The reason your boost is decreasing in higher rpm is due to the loss of efficiency through the interference.

On the video you've uploaded earlier, I've noticed the right hand actuator has a spring hooked on to the base. Will you be able to repeat the test with that spring removed?

Here is the standard actuator travel test as requested... Travel identical as per the external spring.

Here are the long awaited results of the intense billet rs... The dyno graph shows the intense billet rs (blue) vs Hypergear ss2 rev 2 (red) both running just under 30 psi on pump e85 with identical settings and dynoed within days of eachother.

That's a bit disappointing.

I don't blame him, it sounded like an admission of guilt.

Too bad most of us already saw it.

Thanks Rick.

Pretty stoked with how the new turbo feels on the road, The car feels light and responsive in comparison which surprised me given the increase in power. Now I have a genuine 300kw with the response we all chase.

This works well with the stock converter, I am able to easily push 10+psi at stall when stationary allowing a decent launch. Looks like we built the perfect turbo first time around.

Hopefully I can get some time to head down to Calder or Heathcote for a 1/4 run soon, I suspect this will surprise.

That's a 3000rpm convertor?

[Intense m35]

That's a 3000rpm convertor?

No! I'm certain scottys car has the standard converter. He can confirm just to be sure.

[scotty nm35]

That's a 3000rpm convertor?

I sold the 3k converter to Fishingfreak with the GTX kit. My current converter has a stock stator with a beefed up triple Patrol lockup clutch, which I ran to a 12v switch for tuning purposes. It should react exactly the same as a stock box in manual mode 3rd gear.

The blue line stops at 7k, the red was 7600 revs to compare the speed axis.

[BoostdR]

In that case 10psi on the stock convertor (2200-2300rpm?) is a huge improvement over my 2psi. I would expect launch control/ignition retard would work also since 10psi is already in the spool zone. Onto a good thing there.

Is it ball bearing?

Looks like a KTS billet compressor wheel which responds better than the GTX copy billet wheels from what I have tested due to the slim root(lighter, larger blade area per wheel diameter), extended tips(more flow for minimal rotational mass increase), thin blade(lighter, higher efficiency) and high blade design(blade area increase).

Happy to give you a call to discuss it Matt, PM me your number.

It's still a bush core highflow, but there is zero shaft play unlike the Hypergear offerings. I can only assume that's why his require so much oil flow, these do not. I don't think Tao understands VQ25's run over 10 bar oil pressure, even though I have explained it to him many times, why he insists on running such loose shaft tolerances I have no idea, it only forces him to give the turbine/compressor wheels more clearance from the housings which is detrimental to efficiency. He is stuck in RB land.

I would like to get the launch ignition retard working, but I will do that on the Link, my tuner isn't confident on the HKS to get that operating, and I would need a speed input. Time for another ECU upgrade.

[BoostdR]

it all becomes clear. I did note a fair clearance on the comp wheel side...as you say for end float compensation.

Yes speed input is required. I used the yellow wire with black trace from the TCU(it's close to center).

EMU settings: 16 pulse and 32% correction factor.

Tao is quite determined to make up for the previous lack of on car evaluation. We should see some new products coming soon which is all good for us M35 owners..

"how we react after we have made a mistake defines who we are"

yes it got a bit messy while the facts were coming out but we are all flawed in some way. I'm not one to hold a grudge if the offender is willing to make good.

No, The red line was not from the a SS2 Rev 2, its just your turbo running longer dyno ramp.

This is SS2 Rev 2, running 22psi. E85 fuel limited to actuator travel. Compare red n red then Blue to Blue to yours.

The new turbo doesn't appears to be more responsive on paper unless there are other changes made to the car.

[scotty nm35]

lol, someone's a sore loser. I'm getting more and more disappointed with you with every reply.

I only did what was asked of me, I legitimately went out of my way to test the differences between the two turbo's, discounting the fact that my SS2 was a noisy pos shagged turbo anyway. The noises it made at nearly 30 pounds were absolutely hilarious. I couldn't wait to get it off my car. I can't believe you tried to tell me it was normal.

Now you have decided to call me a liar? Shame on you Tao, I was a good customer of yours until this debacle, now everyone is seeing you for what you are, full of crap. Go and check the graph out if you like, as my tuner has advised you want to, try and prove we somehow fudged the figures. Infact why don't you put your car on the dyno and show us how responsive your latest development is.

PS, learn to read a graph, that one is in RPM which isn't very accurate with an auto gearboxes at the best of times... You have a lot to learn mate.

[Ben C34]

Wow. This thread is an eye opener.......

10psi on stock converter with 300kw is a fantastic result.

[Intense m35]

No, The red line was not from the a SS2 Rev 2, its just your turbo running longer dyno ramp.

You really have no idea when to stop do you tao? Calling myself, Scotty and cihan liars just goes to show the level you have stooped too. We have put in a huge amount of work into this development and I think it is very unprofessional for you to be making accusations without facts to back it up.

Fisrt of all. I respect who evers work and efforts in developments of a new product. I certainly not calling any one lairs.

Because the shape of the curve appeared to be quite different to an earlier run I have seen and the comparison had identical ramp up shape down low. Hence my suspicion and questions.

Of course Im not quitting til I beat your result. Further researches will be conducted.

As I read your post " no the red line was not from the ss2 rev 2 it's just your turbo running longer dyno ramp" says you are calling me a liar! There was no suspecision, it was a outright accusation And also if you believe our turbo isn't more responsive and what not, let's just settle this by you coming for a drive!

[Cihan]

While doing our best to keep out of the tit for tat - as both Scotty and Hypergear are Etuner customers - I can confirm that Scott did in fact bring the car back in for another dyno session to be able to demonstrate an apples to apples comparison between the turbos.

14th August : 8495S - 271awkw ; un-locked converter SS2 turbo 22psi
19th November : 9524S - 281awkw ; locked converter SS2 turbo, maxed out
24th November : 9546S - 303awkw ; locked converter new turbo, maxed out

Both are no doubt very stellar results from a "bolt-on" turbo on an otherwise internally standard engine.
