Get your own facts straight...

the Norris Evo makes 550hp at 23 psi on 97 octane unleaded (sold at the pump in GB). 608hp and 574 ft/lb of torque at 30 psi.

It makes 715hp at 30 psi on 101 octane gas.
As quoted in SCC in the August 2003 issue.

 

Oh, and before any ---it was on this dyno or that dyno, etc.

It ran 10.99 at 132 to back up these dyno numbers.

Maybe I am missing something here - or maybe I just can't calculate moon dyno figures

But - I am making very near 420 whp on pump gas with my HKS 3037s - at 20 psi

Your telling me that this guy Shiv tuned made 30 less whp at 10 psi more boost????

BTW - I don't think I ever hit 30 psi yet on my turbo - 28 was the highest I went

here is 20 psi on pump gas

 

I love how you keep acting like you dont know whats going on. You are familiar with how much power it is on a DD.

 

My thoughts are that with the stock engine - 30 psi would push the head gasket or cause the piston to colapse

All of this makes little or no sense

You would have to try very hard to make less than 450 whp with a 3037 at 30 psi

 

Absolutley nothing should be taken away from ND! I think either you are ignoring certain facts (like Al) Its nowere near the same tubo that was used to incorrectly compare to. Or you buy Als goulash hook line and sinker. There is no relevance to the norris in this thread as we arent comparing the same thing.

 

Once again, Norris' accompishments using a GT3240 turbo have no bearing or relevance on the discussion at hand regarding GT3037 turbos.

 

AGAIN You are not stating the obvious what tool are you deriving your majic 450 WHP from?? A DD? I think not

 

Thank you for having the patience and understanding to spell it out for our brothers.

 

ya know what's funny is that hks of japan never rated any of their gt3037's at 500+ hp... the most I've seen is 480

http://www.hks-power.co.jp/products/...urbinesho.html

(look at the first row of numbers... hey, japanese class finally starts to pay off ) now there are a few that are hitting that magic 500 number, but it takes a whole lot of work to get it and a huge a/r like 1.01 or 1.12(which the hks tsukuba super car uses) so I honestly think for their turbo which is small in comparison to all these 3040's and 3240's bla bla, it does it's job pretty well

 

FWIW, according to the Dyno Dynamics Shoot-Out software, the car, at 390whp, is estimated to have 488bhp. Man, I love it when numbers make sense.

925 too

 

Peak cylinder pressure, which is the cause of most mechanical failure, has a lot more to do with spark advance than relative boost pressures. In this case, running just 1 or 2 degrees more than is necessary to acheive MBT results in unneccessarily high peak cylinder pressure. High enough, as you've seen, to stretch rod bolts, turn rods into pretzels and rupture head gaskets. This is possible even without the presence of detonation. So the trick is to keep peak cylinder pressures low as possible while maximizing mean/average cylinder pressures for maximum torque output to the wheels. Without the availabiliy of in-cylinder pressure transducers for actual pressure readings, tuners often rely on dynos to make educated guesses as to where they are on the MBT curve. Some tuners guess right and make a lot of power without blowing up. While tuners who don't usually guess correctly have to rely on NOS, strengthened internals and frequent engine rebuilds to make up for it.

I agree. That's why we are making somewhere over 500whp on one of them thar AWD Dynojet.

We chose to use a dyno as a tuning tool. Not as a comparison stick for those more interested in seeing how they stack up to the competition than actually tuning. Judging by our first time out at the drag strip, I think our method worked pretty well. Besides Al, you are aware that Dyno Dynamics Dynos are more ubiquitious world-wide than Dynojets? They're widely used in Japan, Europe, Australia, Asia and are becoming increasingly popular in the US for obvious reasons. In fact, this time next year, there should be more AWD DD dynos in the US than AWD Dynojets. While 'going with the crowd' isn't high on my priority list, its worldwide popularity as a reference does speak of its merits.

 

Nah, I got it the first time. I'm quick like that...just pointing out that the big numbers they made were not on c16 as you stated.

I will now stop with the thread hijacking...please continue......

 

Al--
Since you brought up the Norris Designs EVO, I should point you to the following link:

http://www.adyscars.pwp.blueyonder.co.uk/videos.htm

Check out the videos of it being tuned/tested on the dyno. Recognize the dyno they are using? Yep, that's a Dyno Dynamics AWD Dyno. Just like ours. The Norris Designs EVO put down 543whp on the DD Dyno. Doesn't sound like much for those who are used to bloated US Dyno whp numbers. But, as you know, the car is quite fast. Despite being tuned on a 'moon dyno'

Cheeers,
shiv

 

This might help explain things to those that don't understand too well, but a Civic I turbocharged made 250WHP on a Dyno Dynamics dyno and 316WHP on a Dynojet at the same boost pressure with absolutely no other changes, about two days apart.
My own car makes 430WHP on a Dyno Dynamics. My calculations put that at 544 Dynojet WHP. From a 1.6 VTEC. I wish more people around here had Dynojets!!!
