turbochargers for 500hp

[Rusty]

Well done chaps, you ignored Paul's request for calm and once again it's the same members arguing away...

Get a cup of tea and calm down.

Thread closed.

on a .63 housing the backpressure will be to big. a .68 would be better.

[A80Avant]

1.8 bar at 4000 rpm on the graph. Worse spool than HX35.
With lots of surge at slower ramp rates due to the 0.63 A/R hotside as well.

0.3 bar does not change much on a 0.63 A/R as expected, as backpressure is through the roof.

Yawn.

Sticking waste gate piston!!!!

How many times do I have to say it?????

This is turning ridicolous...

Yes, of course, nothing I post has any value. Your car is the only super duper car in the world.

Post that graph.

Thankfully our forum members do have brains and realise how fullishly you are turning this thread from a general view to a personal one.

That's OK. Makes your 'business' look very good.

Small correction then 464.8 crank.
Here are the curves from 2011 with no wmi, nitro, race fuel, red bull, morphine, or cocaine

You can see boost and lamda.

my road measurement was not far off with the whp measured at the time.

Once I dig out the 2 bar to 1.9 that I have now you can compare the whp figures and if you are good in arithmitic you ...may notice the difference[emoji12]

And here is the difference. Given that all my road results were within 2% away from my dyno results I trust them. (You don't have to)

Of the 468hp?

I will look for it sure.

What's the point though? Your posted graphs mean nothing anyway.

And if you ever looked into to detail you'd mention that my spool is also worse due to heat porting and larger valves than your stock HX35S examples.

But no you don't mention that as it messes your point, doesn't it?

[prj]

Could we see your awesome dyno graph?

[A80Avant]

Blah blah blah.
Dyno's have SAE correction based on IAT. Enabling WMI instantly lowers the actual IAT in the intake, while the dyno sensor reads the same IAT at the filter, resulting in higher numbers.

So as I said. 468hp with WMI on your car vs 520-530 on HX35, until proven otherwise. I like to post actual numbers, not make them up.

I never used WMI on the dyno ! Nor on my road power runs. And when I did for testing I never get more power using it.

Hahahaha

I only use WMI during hot summer days.

Let's what else you will make up...

[prj]

Where did I ever say I use WMI tuned for it?

Blah blah blah.
Dyno's have SAE correction based on IAT. Enabling WMI instantly lowers the actual IAT in the intake, while the dyno's temperature probe still reads the same IAT at the filter where it is placed, resulting in higher numbers, as it should be.

Cool, so HTA3076R/0.63 with WMI 468hp. HX35S with WMI 520-530hp.
And spoolup is quite similar.

Good to have closure.

I don't so stop making assumptions to prove a point that is not there.

Also as I said my boost curve was a mess due to the problem I mentioned. So again it's nice to see how fake you truly are in this forum and you are doing it on your own with minimal of my effort.

Maybe it's time people started to talk up about your failures on uk forum member cars rather than your 1xx cars you have succesfuly tuned... and still run (??).

@s2 central: I'm sorry but when provoked I won't stay silent. I think it's about time to leave this thread and people realise what kind of person they are getting 'advice' from. The elephant in the living room has overstayed his welcome...

have fun

[Biturbo]

We now doing one car with holset 35s (56mm billet compresor wheel and hot side 8 cm).Turbo from FCP engineering,car should be done next year so will see how quick spool and what power will make.Target 500hp street car for fun

[prj]

I have, you dork. It made 468hp crank on 1.8bar falling to 1.6 and a sticking waste gate due to poor reconditioning.

Cool, so HTA3076R/0.63 with WMI 468hp. HX35S with WMI 520-530hp.
And spoolup is quite similar.

Good to have closure.

Guys - lets keep it friendly please... there is an aggressive tone in this thread which is thoroughly unhelpful. Nobody likes to see such threads turn into "technical handbags" or about bragging who has most experience on this, that & the other.
