2000 variable intake, injectors & TB



The redlines are from my previous dyno before the VI swap.
Not sure on the SAE correction factor but dynojet correction is 5%
I was tuning w/ a VAFC and it took a while to figure out so I think it could still be better but that was after 1.5 hrs.

~174hp & ~186tq

 

Hmm Ive got 4 more HP and 2 less tq....w/out a VI or 370's

flywheel
intake
2.5" straight thru exhaust

 

Try a lower activation RPM for the VI.


What type of dyno is that on? Could be why your #'s are higher hard head.

 

That's great, you have under 150hp at 6500, he has 175hp. His TQ curve is much smoother than yours too.

 

yeah, I don't know what correction factor SAE woulda gave but the dynojet correction gives me 195tq and 183hp

tried every 200RPM from 4400 -> 5400 on the VI activation, that is the smallest dip at switchover

those are only 290cc injectors btw

 

Sweet looking curve, mean gain in the midrange, something us MEVI folks cannot say.

 

Hmmm.. this was on a DynoJet? 5% is a lot of correction.. but that A/F looks really rich. Try leaning it out a bit to 13-13.5...

 

No this was not on a dynojet, a dynojet will read 5% higher than this one.
We tried leaning it out, that was the best we could get it 33 pulls later. Took a while for me to figure out the VAFC settings. So after an hour drive to get there and then 33 consecutive pulls, she was a little warm...

 

Oops sorry... misread it. Yeah I guess heat soak would play into things too. You're running DE-K injectors right? How far can the VAFC adjust the a/f?

 

Well if any of us knew how to use it properly, prolly as much as needed. Didn't have the manual w/ me, didn't think i was gonna dyno today. Only reason I went to this place today was because that's where I did my base runs. They are mainly domestic... LS1, Mustangs, etc

 

Hmmmm, Ive got 31 more hp and 18 more tq than you.... without 2000 VI or 370's. You know better than to compare numbers between different dynos and cars and areas of the country. You and me on the other hand, went to the same dyno. You do need a VI though, I have almost 60whp more than you at 6500rpm.








to stay on topic, nice gains from the 2000VI jmeister.

 

So I take it you'll be doing another session soon then... I haven't dyno'ed since my swap but I will be in the next week or so and I'm curious how rich my A/F will be after seeing yours... I don't have any piggybacks at the moment but as a quick fix I may get JWT to reprogram my ECU for the 100 bucks.

 

until the jwt or ts is installed

 

But he doesn't even have the ECU, so imagine if he did ...

 

True might get an upgraded ECU myself or at least a SMT-6 or SMT-7. Anybody know how much they cost?

 

smt-6 is like 400 i believe. dunno about the smt-7. Im debating between saving my money for a 5 spd, or going for an ECU...errrr

 

I wasnt trying to brag...just pointing it out. His numbers seem kinda low

 

That is one funky looking graph.

You guys should not let that graph fool you. That mid range gain is not due to the 00VI, it is mostly due to the AF raito being so rich in the base line pull.

I would not be happy with that curve. You power drops from 4K-5.5K then goes up slightly to redline. The dip at the switch over is not good at all. I am sure with better tuning the power curve could look much, much better.

 

There may be some afr issues, but I also saw a very nice mid range gain after installing the 00vi, and so did BSwithTF.

 

But that was over an MEVI correct?

 

Yes, that's right, I forgot about that.

 

Actually the dip is where the VAFC switchover is set @ 4800, the actual VI switchover is set @ 5000, I believe, or 5200... can't remember. I didn't have the VAFC manual and didn't realize there were 8 more correction points for high cam so the dip is where the VAFC is controlling AFR up to 4800 then it cuts out and then the ECU is trying to correct after that. The next screen we didn't even see/use for the AFR at high cam settings, that's why no matter how much we tried to lean it out after 4800 it never would.
So basically I wasted a lot of money for something I didn't know how to use at the time and neither did the shop. Need to talk to those guys and see if they'll cut me a deal or something to tune it again.

 

Just had my first dyno done on a Mustang Dynamometer and got 200 tq & 183 hp but I did not go to redline only to 5300rpms If I can find a scanner I will post it. My A/F goes to crap as the rpms climb, starts from 13.1 at 2300rpm to 10.9 by 4500rpms. My tq goes from 195 ft-lbs to 90 ft-lbs when the A/F ratio drops to 10.9. I definitly need to do some tunning.

 

Went back this week and got it tuned better.
AFR 13:1
205Tq
195Hp

 

I just got my VAFC 2 today so I will be hittin you up to see how you set up yours.

 

Graph?

 

Just had to make me scan & upload huh.
Sorry I was a bit wrong on my correction #s and I'm still not fond of the switchover dip set at 4800. Previous baseline graphs on page5 of my homepage.

 

very, very nice.

 

Nice numbers, you need to raise your switchover by about 4-500rpm though. You are missing quite a bit of area under the curve from that.

 

Yeah, I realize the loss in torque but it didn't make much difference when I had it set at 5200, might need to go higher still.

 

If I remember correctly, my switchover is at 5500-5600rpm. I had to go that high to get it to smooth out. We have alot different mods though, each one person's will be different.
