The car is dynoed and going to the track

[fabio420]

Well, I couldn't wait. I got the car dynoed without the new Z32 MAF and the new injectors. Once I finda way to scan the results, I'll post them. Basically I put up at 10 psi and my numbers were 220 rwhp and 245 lbs of torque. I'm gonna find out tonight what that translates to in the track.Here is a link to some pictures of my car. One shot show how I've hidden the BOV.http://f1.pg.briefcase.yahoo.c...om/

[DRIFTEADOR]

the link's not working, but congrats. is that on a safc?

[fabio420]

Yeah, I'm using an SAFC II. As for the pictures, There's something wrong with yahoo right now. I'll try to figure out a way to shrink them and show them here without having to link to somewhere. I'm also getting a new intake and downpipe custom made.

[Jookmasta]

hey whats ur setup? congrats on the numbers..............

[fabio420]

Here is my setup list, followed by the next few scheduled upgrades to come:xs T3 48 a/r ehxaust housing and 42mm on the other side( it's small but full spool @2400rpm!!Stainless steel T3/T4 exhaust manifoldxs intercooler (bar and plate) 3 1/2" thick 27"long 7" tallXs wastegate with a 5.6 lbs springxs BOVSAFC IIGreddy profec II EBCCustom (self -made with some friends) ic pipping and oil feed/return linesPlus I already had a test pipe and full catback exhaust from pacesetter.This resulted in the numbers I've tested at earlier.I am adding to it this week:370cc's injectors (SR20)z32 MAFCustom downpipe 3" and side bend intake pipeWill definetly be getting new numbers then.Oh, and I'm trying her out at the track tonight, so I'll post some times. (My friend has a supre MK3 that he's trying to beat me with)

[Craving4Boost]

if your not using the 370's yet what are you using? fmu?

[eddiec]

he said he's running a SAFCII.

i didn't think the stock injectors or MAF could handle 10 psi. but good numbers anyways.

[Craving4Boost]

your using an SAFC with stock injectors?? and boosting 10psi with a t3? risky...

[fabio420]

In the dyno, It leaned out at 14.1 psi. I'm actually running pretty rich @ 9 psi. The new injectors are coming in, but with my fuel/air ratio gauge and after tuned, it doesn't appear to lean out on me. Couldn't hit the track today because of the rain. I'm DYING over here

[fabio420]

Neither did I, and that's why I didn't run it on my own and waited to try it on the dyno. But in testing I was safely pushing past 10. It leaned out on 14 psi, so I'm running 9psi and my fuel/air ratio gauge is constantly showing stoich to rich. (once I get my hand on a scanner I'll post the dyno sheets)

[Jookmasta]

those a/f guages arent too accurate so be sure to take the data acquired from them with a grain of salt...................

[fabio420]

true! that's why I base it more of the dyno. I only look at the gauge when it is full throtle open.

[WDRacing]

NICO has free picture hosting.NArrow Band AF gauges are useless...use a wideband or none at all. 9psi on stock injectors with a SAFCII is probably a razors edge from blowing up. But it would be cool to see a dyno chart with a AF map plotted with the stock injectors installed.

How?

There is a sticky at the top of this forum...

You do realize that the narrowband AF gauge begins to read rich at 14:1AF most of the time right? I've seen on my car where my PLX is reading 12:1 and the narrowband is reading in the yellow area.

Why didnt' you use a wideband when you were on the dyno?

If I were you, I'd turn the boost down to spring pressure(basically turn the EBC off or bypass it) and prolly not even boost. No offense, but thats just dumb to even attempt to make more than 190whp or so on stock injectors. And why buy a Z32 MAFS before getting larger injectors?

IDK, but be careful man. Don't want to hear another blown KA-T story...

[Florida240sx]

Why we are here talking about safc and mafs. Getting IAP kit.Buying z32 monday N62 model and i got the safc.Getting 555tomei injectors and have a set of sr370 injectors. Looking for 250ishrwhp Probably going to run 10ish lbs. Trying to avoid spending more $$$.Only Dyno in town only reads rwhp. What should I do. I can keep it under 3500 rpms and make a trip to daytona or orlando.To get on a dyno with wideband.

[fabio420]

I actually got the Z32 maf AND 370 cc's (SR20) injectors. The car was dynoed with a wideband sensor. I can't explain to you why the car didn't lean out until 14 psi, but in the dyno, with the wideband sensor hooked up (that's how i tuned it) that's where it pushed till. Maybe it is because I have an 8:1 rrfpr. I don't know. Like I said, I am installing the bigger injectors and MAF and new downpipe, but the temporary setup I'm running right now has been taken to the dyno and tuned with the SAFC using a wideband sensor.

[nissanfanatic]

The 8:1 fuel pressure increase is why you didn't lean out... But you do realize that at 10psi, your fuel pressure is 123.5psi right? And at 14psi, it was 155.5psi? I can't remember exactly where the map was, but there was a flow map for the walbro. And at the points I just listed, supposedly the walbro wasn't even flowing anymore. It leaned out because the fuel pump was no longer flowing anything.... Or because the pressure on the pintles of the injectors was too high so the no longer opened and/or opened as far as the should.

Any AF ratios? So if you "got" the 370cc injectors, install them... No point running the 8:1 FP rise anymore with the 370s. You'll be able to run safe fuel pressures again.

[Red-KAT]

At 50psi FP my 370's can baraly eek out 13psi at redline, were talking 99% duty here... (note this is 1:1 so 63psi)

With stock pressure you should be eek'n at 10psi.

[fabio420]

So here finally are the pictures of the car. I'm working on getting the dyno results scanned and postedhttp://nissaninfiniticlub.net/...age=1

[Craving4Boost]

looks good, not bad at all. wow it seems as if the KA-T is really booming in this forum. it's great

[sanioll]

very nice. Your homemade heatshielding technique is spectacular. Taking the fact into account that, heatshield will heat up, and then stuff underneath will abosrb the heat too. There has to be a little airflow under that heatshield.

Your air filter too. Make a ram style air duct forwarded towards the air filter.Custom made larger intake can be fitted under the bumper lights. You know the small plastic grill under the bumper light. you can collect air from there, and direct it towards air filter.

Closer the intake charge air temp to ambient air temp, less chance of detonation you will have.

P.S. also, do not push it hard for long on a stock radiator, especially when it is summer.

[fabio420]

Thanks for the kind words. I thought about the airflow issue, and that's why I chose that box design. I am getting a couple of custom pipping made for the intake and exhaust, ad I'll be taking your advice into consideation. Also, I was planning to put a similar metal plate aroud the base of the air-filter, to create a separation between it and the turbo. I figure with this disruption the air in that vicinity should get a little cooler, and it's an easy design. What do you think?

[s86d]

Dude reroute that hose coming off the turbo inlet coupler that looks to be hooked up to your (looks at picture) WTF IACV!? (first off it looks like its about to become FAN FOOD, second isn't that supposed to be routed into the coldpipe going into the throttle body?) If you are having stalling issues that would be why, but at the least get zip strips.-Dave

[Red-KAT]

The hose to you're IACV should be from a pressure sorce... Or you will have 10psi on one side and -5psi on the one you connected... If you attach it to pressure you will have 10psi on both sides and yer IACV will last longer. (from what i understand)

Like this... little black hose on the right of the cold pipe.

[fabio420]

you are 100% correct, That was just the setup I had when I was first running the car. I have a piece of pipe with 2 nipples on it now. What does the skinny hose that's originally attached to the intke pipe do? I've been riding my car without it being connected for 5 days now and no problem. I'll put up some more pictures after I go to the track tonight(MOROSO), and some new dyno results.

[s86d]

If they were vacumn line small then I would say vacumm sources. I plugged them up. The large vacumm line that went to the carbon canister can be used as a boost source I tee'd it in to my wastegate signal instead of using the common brake booster vacumm hose on the firewall (WARNING TO ALL) Nissan discontinued the preshaped brake booster vacumm hose.

So, should my idle speed control hose be near the turbo, or by the throttle body? My buddies tell me it should be on the turbo side because it shouldn't have boost in it. I'm running mine now with a real pipe with fittings(nipples) and I have no idle prblems or stalling out, so the way its running now works. Is it wrong? Should I even bother to change it if it is?
