I went to the dyno today

[bakes]

This has always been the opposite for me, I always make more boost at the track than on the dyno. (Well, except for the last time out! lol)

Same here the more load and longer the shift time the more boost i could make between shifts

[boost geek]

The turbo he is running can easily hit 40+ psi on a 5.9 Cummins diesel engine, so he should be able to hit that boost on a small 2.2L.

But do I have enough exhaust flow or energy to spin the large turbine housing and wheel to 40 psi? Is a tube header needed?

[bakes]

Oh a tube header is always needed!!!!!!

LOL, well I always seem to be the odd one out,

Well boost is a measure of restriction, and your spooling that sucker up around 4K, so yeah, you should easily be able to make 40 psi, unless my understanding is wrong.

Agreed with Bakes, tube headers are always good,

Yes, Yes, Yes.
Your canister just isn't holding shut, then you start creeping because the holset wastegate holes are too small for gasoline engines.
If you don't believe it, wire that thing shut. Just don't kick me in the shin chan when you are done.

[boost geek]

OK, I guess I know what I have to do next.

Or use a vacuum pump to lock the gate.

thanks Brent for you help ( ps you need to come up for a weekend when you get some time 2 hours away from Misson)

10 mins for me,

Before you go wiring things shut and changing spring, simply unplug the W/G can and verify that your boost controller is capable of cutting the signal to it.

It always baffles me why so many think internal W/Gs are so bad? I would never waiste my time with all the extra piping/hardware of an external W/G when an internal works just fine.......

Hey that will be fun, junkyard, vs toolshed .... get vids!

[shackwrrr]

If the pickup is wrong then your torque numbers are wrong but your HP is correct. Meaning your torque is inflated. That should be obvious to you since your HP is still going up at 7k rpms, meaning your torque is NOT dropping off.

Actually its the other way around, the dyno measures the torque then uses the torque x RPM / 5252. So his torque numbers are as measured from the dyno and the HP is calculated. Either way the line is correct, just compressed to the left. Hp can still rise even when torque is falling because you have such high RPM numbers in the equation and anyway his torque is not falling it going flat so same torque with higher RPM ==== higher HP.

Yah, hence why the running joke about "Honda horsepower" torque blips, but the revs go to the moon...

Exacarry.

I'm generally not impressed by horsepower, but that damn James Watt makes it something we all get excited over.

Stop with the sillyness already, you know by now your doing it all wrong,

It will happen, maybe even the next Street Legal, muhahhaha

i wonder if the alky system is to much streaming and not enough mist! and water droplets are putting the spark out?

Not sure how much he's using but Marko uses a multiport setup on most of his builds now, he's ramming thru gallons of it.

[boost geek]

I don't think there is spark blow out.
Alky doesnt come on till about 22, maxes at 27 (3) bar.

What's your alky setup again?

[bakes]

devils own . he drilled out the nozzzle and turn up the pump my worry is is it misting or the jet streaming.
