Ok thats kind of scary.......I logged 440 g/s..on one of my logs in 3rd gear and i though ok that is ridiculous. I agree i need a baseline. Thanks Brettus

 

/\ Gregs had similar numbers but ended up with 290whp - so yeah .

I've noticed a LOT of people around here show MAF numbers out of whack with what they get at the dyno .

 

At one time I had maf readings of 320 g/s with 260 whp on the dyno. It made sense. Flywheel hp with say an 80% drivetrain loss. Tuned by MM.

I ran well over 400 g/s at the last dyno but had some unknown problems above 6200 rpm, netting less than 250 whp.

in truth, if you want to know your numbers, take it to the dyno.

 

I am days away from ordering my turbo kit!! Getting pretty excited but I'm not planning on doing the install until the end of the summer. So AccessPort and guages will be ordered throughout the summer months. But to carry on from something we were talkin about in another thread, if I am using the stock cat with the turbo kit and an AEM UEGO A/F guage, is the guage sensor going to be safe in the greddy downpipe bung or will it get too hot. NGO was saying that he has his stock wideband in the downpipe bung, does that mean I should put the AEM Wideband in the stock cat bung?

 

That is where mine is - but my cat is gutted ...

 

Yeah I figured the Cat would cause problems for the aftermarket wideband... is this just because the stock WBO2 sensor is designed to handle a higher temperature?
Brett I'm assuming you gave it the old "hammer the pipe down the cat and shake out all the debris" trick to gut it... I imagine this is what I'll do for a temporary fix until I buy a single resonated midpipe with no packing in it *cough BHR cough*

 

Well, I've been to the bank and my money should be in the proper account by Thursday at the latest so I can order. Going with the GReddy turbo kit, HKS SSQV venting to atm., Cobb AccessPort with MM tune, AEM UEGO AFR and an Autometer mechanical boost guage. I will be gutting my stock Cat, moving the stock WBO2 sensor to the GReddy downpipe and the AEM WBO2 sensor to the bung in the gutted Cat. This is just going to be my initial setup and I hope to later add a BHR midpipe and Ignition upgrade with an eventual turbo upgrade as well. This will be my first time with an FI'd vehicle and everyone here has been a great help... so a big thanks is in order to all!

 

scaling is off, simple as that

 

or a boost leak

 

Turbo Kit and BOV ordered from BHR!

 

cool - what turbo are they supplying ?

 

Ordered the GReddy kit from them... and SSQV. Super pumped to go FI but I'm probably not going to do the install till September so that I still have my car for the the summer, after all it is my summer vehicle. Also I am away from home for the summer, this way in Sept. when I'm back home I will have my truck to drive while I do the install on the 8.

Edit: Also just ordered an AEM UEGO A/F Guage.. gonna gut my cat and put sensor in the cat bung with the stock wideband going in the downpipe bung.

 

You will find this a right royal PITA - unless you enjoy humungous backfires .

 

It won't be leaned out when you get MM's custom maps for the accessport? If not I'll have to buy a recirc. piece for the BOV if it gets too annoying.

 

/\ you can't tune it out . The air vented by the BOV causes the maf to report more air consumption than actual and way more fuel than required is injected .

The other drawback is that you can't tune your bov to crack earlier (under part throttle). The boy racers wont care about this but it does make a difference in drivability .

 

^ Yeah I understand what happens... just didnt know if you could tell the pcm to reduce the fuel injected when you release the throttle or not.... well I guess we'll see after it's all installed if I want the recirc or not.

 

Can anyone tell me what the typical fuel pressure readings from the stock fuel pump are? I am thinking of going with fuel pressure for the third gauge in the Lotek pod but I need to know if I'll need the 0-100psi or 0-30psi ranged gauge?

 

You would want the 1-100 psi. a properly working OEM pump is in the 45-55 psi range.

The Walbro supplied in the BHR pump upgrade is 60 psi plus at the fuel rail.

 

Okay thanks.. and an upgraded pump is probably on the horizon as well...
