Finally got my wideband and EGT in. EGTs under long, full-boost runs never goes over 1000F. AFRs at full boost are between 10.2-11. Highest I've seen at WOT was 11.1 which I think is really decent. Maybe too 'safe' for some of you, but for the 2.4 people, I think it's just right . This is at 15psi.

So the run down, I got this setup with an S60R mani, 3" downpipe, 16T, white injectors, speedtuning stage II tune and other little mods that don't make a difference. I think with this much fuel it could easily handle 17-18psi, but I'm not planning on trying it anytime soon. She's plenty fast to scare the crap out of people already.

Anyways, just thought I'd put it out there for any of the LPT guys. There's a lot of debate over what tune, injectors etc. to use when going HPT. Just found a setup that works pretty decently.

Thats great. Thats the exact same set up Ill be running. Cant wait just need my injectors to get here.

werd hmmmm .

PM me your address again I am going to UPS tomorrow to check on the tracking they should of been there today

Hey wagoneer85...have you taken your car to the track with your current set up? Interested in seeing if you improved your 1/4 mile time. 14.3 wasn't bad at all.

[matt b]

That's the same set up as mine. Isn't yours a manual too, now ?

16T, 3 inch exhaust, blue injectors, IPD Stage II tune, I think I hit 15 psi on this set up.

[adamjjohn203]

Me too...I have whites stage 2 IPD etc....I'm hitting 17-18 PSI.

Haven't been back to the track yet, I'm hoping too before it shuts down though. Should be within the next month. I think whether or not I improve will be down to my shifting skills. The manual is tricky to launch. I've done a few runs with my iPhone and it's been pretty consistent at ~13.8@103.

I think so, I've got three pedals

I was thinking about blues just to be safe, but it looks like whites are pretty capable at this level.

You have an AFR or EGT? Interested if my results are like others' with similar setups. You're brave running 18psi, there's very little room for error in tuning with the 2.4 block. Honestly, I don't trust the speedtuning tune yet until I get it on a dyno and see the graphs.

[adamjjohn203]

Yeah I need a wideband for sure. I'm pretty confident with the tune Lucky set me up with! I ran that tune for over a year and had the engine gone through and there was no sign of damage. The boost is limited in 1st to 7psi and 13-14psi in second....right before it shifts to 3rd is when I see 18psi.

I ran 17lbs on a 16T, stock injectors and exhaust with an IPD T-5 tune for 3 years. Car was scary fast. I believe the GLT's are geared differently.

Stock injectors? My reds couldn't flow enough at 100% duty cycle.

GLTs don't have different gearing, the TCU is tuned differently. My car reacted a lot differently than my dad's 854 T5. Then my indy found that all the LPTs have a different TCU and the throttle positions are different.

[Yellow95]

Sorry but a TCU cant make the gears shorter. It can only effect shift points. My opinion is that the gearing is different. What told you that your reds were at 100% duty cycle and at what maf flow?

Never said the gearing was shorter? Or was that what you thought?


Did some highway testing. At cruising the AFRs seem to fluctuate back and froth from 14-16... constantly at a perfect interval. Is this normal? It's annoying at night, lol. No fluctuating during boost, just when cruising. Also, the AFRs are a lot higher on the highway, obviously from always being at higher revs. It settles around 1200 but reaches 1400 when accelerating. Is this normal? What do other's have?

Fixed.

AFR fluctuation is normal. EGT 1400ºF is OK under constant accel, if your probe is right after the exhaust housing. Temp should drop off fairly quickly when you back off.

When do you plan on doing the dyno?

I'd be interested to see the hp/tq and to know how this would work with the auto trans in the S60 2.4t. What do you guys think?

it only gets up to 1400 while accelerating on the highway. As soon as I'm back to cruising it goes back to 1200. And the probe is as close to the DP flange as possible.

There's a group-dyno session going on with a local car club in the city, I'm going to try and get a spot if I didn't already miss it.
