Back from the dyno part 2

[shadow88]

Part 1 showed a lack of fuel supply, that has been corrected with a 255lph fuel pump and a set of +40 injectors. Thanks to GLHSKEN and Simon.

I took some detailed notes and thought I'd share them.



Runs 1 and 2.
Run 1 stock smec 12 deg. ingnition timing, 32 psi fuel pressure (how I drive it to work) Made .8 volts of knock, boosted 19 psi by 3800 rpm's and fell back to 16 by 5800 rpm's.
Run 2, same as before but added 2 deg. ignition timing to total 14.



These are runs 3 and 4.
Run 3 mopar performance smec and 14 deg. ignition timing. knock output .74 volts. Boost pressure 21 psi at 3800 and fell to 17 at 5800.
Run 4 same as before but added 3 psi static fuel pressure to a total of 35 psi. Boost was the same.



Runs 5 and 6 used a custom cal and 3 bar map from Dean Stillie.
Run 5 had 35 psi static fuel pressure, no knock voltage, and 22 psi boost at 3800 rpm's falling back to 17 at 5800.
Run 6 added more fuel pressure to a total of 40 psi static, same boost pressures.

More.

This is runs 5 and 7 together.



Run 7 still had the custom cal smec, 40 psi fuel pressure, no knock, 14 degrees timing advance, boosted 22 psi falling back to 19 at 5800 rpm's. This is a back to back reference of running with an exhaust cut-out.

I'm very happy the car stayed in one peice, and I have to imagine the manifolds I made for this car were totally worth while.

thanks for looking. Any feed back is great.

good pull im glad to see you got it tuned to run right

Not bad at all,

What turbo again? lol. My memory is going.

Stock turbo 2 garrett. Maybe time for a better one?

[devlish]

Over 250whp on the stock turbo2?? not bad i say. everything seems in check as well. why is the boost falling off 4psi by 5800 though? is it spiking at first or just the turbo too small to stay put at higher RPMs??

Very impressive. Its never a bad time to put a bigger turbo on,

Yep, turbo is too small or the wastegate can can't hold the puck closed due to exhaust pressure.

[shadow88]

As far as the boost pressure goes, there's 3 washers worth of tension on the waste gate actuator bracket. It spikes to 22 and falls back as the need for air grows I suppose. A liitle bit too small turbo, a little spike.

I hope the runs 5 and 7 help with the "how much power will a cut-out get you" debate.
After mine, a buddy's srt-4 stage 2 ran 270 whp and 315 wtq. the battle continues.......

You hit the nail on the head. Boost falls off because the engine is swallowing it...

I also back to back tested a cut-out. 11 whp and 22 ft lbs was my gain.

Yep, I had mine locked shut with a vacuum pump,

[shadow88]

You lock your wastegate closed? No wonder you make such silly boost.

I did on my stock engine with the TIII turbo. I would sit around 22-23 psi at the track.

This new engine with the T3/T4 will boost over 35psi with the wastegate unplugged,

Hmmmmmmmmm, hybrids sound like fun. Are they the same size as stock turbos? I don't have a great deal of space back there.

Yes, they are fun. They are larger than the stockers of course but will fit with no firewall issues. Some fabbing, grinding etc is needed. I used some rubber elbows from a RX7 and no grinding is needed.

Is a hybrid worth it over a S60 on pump gas and 21 psi?

[cordes]

Is a hybrid worth it over a S60 on pump gas and 21 psi?

At that boost level I would say so.

[turbovanman²]

At that boost level I would say so.

I would agree,

[shadow88]

This is part of my dilema. I've picked up 6/10ths of a second and 7 mph since making my new manifolds. I really don't want to loose that by going with a stock exhaust manifold or a TU manifold.
This is also why I was looking for feedback on the super 60's here. http://www.turbo-mopar.com/forums/showthread.php?t=7551

I already had to hammer the firewall back a touch for the tbi header to fit. And had to make my own swingvalve. I was hoping to use a turbo that took up *about* the same space and used the same swingvalve bolt pattern because then, I'd just bolt them on.


Can any users of either turbo (s60 or hybrid) confirm the swingvalve compatibility, and odd ball chrysler flange bolt pattern, and aproximate size comparison? Thanks-Jaim

If you get the Turbo Mopar specific turbo's then the stock Garrett or TU's 3 inch SV all work. If you get the T3 flange, then all bets are off and you have to make a custom setup or use a Ford SV and the FM elbow setup for the R/T.
