Parts (Importdps, Xenocron, and Verocious)
Tuning (IMW)

The purpose of the original thread was was to make a manifold that would produce power power and not creep excessively. I would say on both accounts this effort was successful.

See link below.

And the plots





The next step is to turn up the boost via manual boost controller. For this step, I plan to use either e85 or C16.
We plan to see the power produced at the current wastgate pressure (11.2 psi) and approx 18 psi.

We have a tuning appt on 6/11.





Side note: I guess all motor cams don't work very well, LMAO.

 

I forgot pics of the set-up in a 91 honda civic HB

 

Just out of curiosity, what's up with the dip in the torque? Must feel kind of weird to drive with that there, kind of like spooling twice lol. Is it from the cams?

 

^^^vtec should be set higher but 7k is a little harsh on the vt at that high of engagement. No, it does not feel weird or spool up twice. Lol, a 10 ft-lbs drop and I should start over.

 

pretty flat torquecurve IMO

 

Looking forward to this Saturday.

 

your vtec should be set to 5250. That dip needs to be tuned out, afr or timing. Can rev alittle higher

 

nice

 

good luck man hopefully my set up will be done soon ill let you know how it goes.

 

is that a AEBS intake manifold? mind sharing what internal work you had done to the intake manifold? looks like it was cut open.

 

id almost bet that the dip in the power band is from the cams... i tried a set of pro1 and pro 2 back to back on my turbo car and the pro 2 did the same thing.... made more power everywhere with the pro 1 and the HSL made more compared to both. just a thought

 

That cam setup is probably a good start.. you'll want a exhaust cam with a better ramp angle and ramp speed.

The exhaust cam needs to snap open the valves quick enough to let the exspelled gases out, but not so long to where boost is actually blowing out on the overlap.

Good setup non the less, i'd try something like the pro2 intake and pro1 exhaust...maybe a s2s3 exhaust, possible.

 

i have a dip like that using ctr cams, but it comes on a bit earlier, around 6500.

all in all it looks good, especially for 11psi. the setup holds tq well to 9000. it must rip in the ef

 

This website is F'in incredible...he is at 11psi and making 380, he's happy...why the hell "should" he need to change anything?

John Kerr and IMW are competent people, and they were THERE when the car was tuned, you werent. You dont have to tune out any "dip" ... its there, its called VOLUMETRIC EFFICIENCY, Google it

Nice job Marcell...must feel nice!

 

I honestly wasn't saying anything "against" the build or setup, or even tuners.. i was just suggesting something else, to what someone else was.

@ 11 psi making 380 is very respectable.

 

Thank you for saying that. I love how everyone is a better tuner over the internet. John and Derek know what they are doing and would have tuned out the dip if it was a simple fuel/ignition issue. This car rips for sure and the 10hp dip isn't even felt.

 

Oh yeah?

Please, come tune the dip out for me. I've never tuned a car before.

Wow, this thread has some comments.

As Furyof4 said, thank you xenocron for your comment and yes it moves pretty good. Sometimes, HT can go a little off kilter.

Also, I appreciate everyones input.

Fred and All motor, I am considering what you said seriously.

GEN2_LS, the manifold was hand ported by Tonio on here.

As for the dip, please observe the plot below. It is a comparison of Boost vs NA



The "dip" was there when it was NA.

Let me make this as clear as possible, I have all of the confidence in the world in my tuner. He knows exactly what he's doing. This motor has seen more than a hundred pulls on that dyno. It's still going strong. I think we can all agree on this point. There are several factors which enable this engine to last so long: (1) the motor is well taken care of, (2) the quality of the build is good, and (3) the tuning has always been excellent.

Finally, I have a car that my wife thinks is fast.

 

+1 for D-rob
+1 for a awesome setup

I'm working on a set of cams now for a turbo car, should be posting up some good results here shortly.
Made 857 @ 35psi on pro1's and he just bought a set of my stage 1's so we'll see how he does, i'm using the idea i gave to you, with a smaller exhaust cam with a faster ramp speed.

 

I hope this is a track only setup.

 

^^^lol, why?

 

my bad, I didn't know who tuned the car. I didn't realize you'd get all butthurt.

You couldve just said that dip couldn't be tuned out.

 

LOL, yes, I'm very butthurt.

I'm just trying to figure out where your magical 5,200 RPM high cam engagement engine speed came from. :facepalm:

 

Lol. 5250 is where I think vtec should engage. Where did u set it at? Am I wrong?

 

That's fine and dandy, but why?

Where in the torque curve do you see setting VTEC at 5250 would benefit it?

And can you tell me where VTEC is currently enabled?

Trust me, setting it lower that it is now kills the curve. Horribly. It could still stand to go up another couple hundred RPM, but I'm not into over-working the low-cam rockers.

What about this graph?



Where should VTEC be? And where does it come in at currently?
