Redyno a little better this time

Yellow4g63 · 07-03-2006, 11:02 PM

Went back to the dyno after changin out my core cams to my spare SR16 ones. Mods are the same 2.5 exhaust with a 2.25 cat lol, Stock SR20VE header and warm air intake.

Run number 8 is the SR20VE cam dyno from last time.

Nice numbers

Get a 3in cat and exhaust, it help me alot. I went from 2.25in to 3in and there was a noticable difference IMO.

Yellow4g63 · 07-03-2006, 11:18 PM

I would but I just don't want it loud. The car is sooooooo quiet with the 2.5 it's not even funny. If you watch my vids you can't really hear my car most of the times.

hey man how much does it cost to get a dyno?

BORNGEARHEAD · 07-04-2006, 12:42 AM

Wow, I really like the way that graph looks with the sr16ve cams. Nice increase in power through the rpm band. Now I really can't wait for my 16ve cams to arrive.

Nice job.

Down here it's $40 for 3 pulls with the wideband. $100-$125 an hour to tune depending on what you have to tune with.

hmm i see...thanks for the info....

Peanuthead · 07-04-2006, 12:57 AM

What are the cam switch points?

tHe iLleSt RiCe · 07-04-2006, 01:57 AM

nice to see the power doesnt drop at 72xx like the sr20ve cams! Man, now you HAVE to hit up the track this weekend too man! haha

Isnt that switchover a little too early? I recall guys recommending late switchover in the 5400 range??

Cheers-

Edit Note: What the hell is up with the huge jump in AFR??

Yellow4g63 · 07-04-2006, 02:46 AM

Not really if you look at a few post Andreas set someones VE with 16 cams to switch at around 4kish both cams at the same time.

Wicked R · 07-04-2006, 02:48 AM

Thanks for that info... I've got 16 cams in my VE motor thats waiting to go into my SE, so thats good news to know...

Cheers on a job well done!!!

Also note that I wasn't there to tune just to get 3 runs in. So he let me do a few changes. If I had paid to tune I would have tried everything lol.

billc · 07-04-2006, 09:13 AM

I'd be very pleased with these results. What ECU and MAF are you running?

RB20 MAF and Calum ecu with some minor changes to his base map.

Just curious, what changes did you make to the calum map and what are your impressions? Ive been running mine for a week now and im really happy with it compared to the JWT. Gas mileage is improved slightly and my low end torque feels much better (it doesnt surge like it did before after 5k). I will be tuning mine after my cams are installed and i get some funds.

Also, why the stock header? Are you holding out for something? The autochrome ones seem to be pretty good and they are dirt cheap. Nice looking curve though, the cams really hold the power up top.

I changed the fuel maps on mine. It ran very rich when I got it. 10.8-11.2 lol. Then I had to mod the injector lag time a little too. I haven't really played with the timming at all yet, the stock VE map looks pretty healthy. I'm holding out on a header made for the VE. I talked to Pro-tech about making so thats why I'm running the stock header right now.

my problem *** vvl is the tq drop why does it drop off like that. nice hp numbers btw but can someone please explain what the problem is?

Yellow4g63 · 07-06-2006, 01:28 AM

Not sure what you mean. From DE dyno's I have seen the tq drops off too? I don't have aftermarket headers either so it's not helping TQ either.
