Stroker;

I totaly agree about the lateral G's. The G tech isnt so good with the lateral Gs because it doesnt have a pitch correction for how much your car will roll in a corner. It is good for tuning your car to achieve maximum Gs in the corner, but you wont know what the lateral Gs really are until you drive it on a skid pad. A 200 skid pad can be made in a parking lot. Basically time yourself around the circle and calculate what the G force must be to maintain that circle and time.

That being said the forward Gs are much more accurate since the new G-meters have a correction factor that can be calibrated against real runs to hone in how much your car will actually pitch during take-off (so many degrees per G sort of thing).

With nice ZR racing tires (properly matched for your cars weight distribution, ie. 245's in the rear) and a suspension kit on your car you should expect to reach somewhere just over 1 G in the corners (like 1.05 to 1.1 Gs) but dont expect to reach anything over .8 Gs with street tires. Please also note that tuning suspension geomatry is a topic way to involved to get into in this post. Let's just say there are a lot more things involved than just installing a kit and going.

EDIT-------------------------------------------------------------------------------

I'm editing this post because after reading this post again, and after further consideration, I really don't think it's likely that a street legal fiero is going to reach 1 g let alone 1.1 g's. I think .95 is a much more likely number.

Your only limitations are set from within, by a lack of vision.  But to have vision alone leaves the process idle.  Ergo, without action your thoughts are worthless.

So , hows everyones project going? I drove mine home from oakville to kingston without fault. Took it to a 2 day long car show in kingston and Won my class and Peoples choice for the whole show.

Going to pull it out this winter and swap the heads and cams.

Also ordered a Wideband O2 meter with data logging

Nice job...

...so I take it the cams and such aren't for sale anymore? That's okay because I'm not going to have the money for a while anyway.

Congrats again.

As far as the projectI have the idle working nicely, but I find that after a long run (say 30 min or so) the intake air temperature is getting a bit higher than Id like it to and its causing the motor to run a little rich momentarily when I let off the gas.  So two things next on the list is, change the radiator for a Nova rad, and insulate my cold air intake.  The car doesnt run hot but it is running a little hotter than Id like it to by about 10 to 15 F.

The Nova rad is a drop-in replacement?

no, it requires new brackets because it's a few inches taller.  No big deal really.  I'm going to try and find a copper one with a single wide core.

Ditto.  I bet the stock v6 radiator would work if it were brand new, but on a nearly 20 year old radiator, I think mine's a bit overloaded.

I've been watching this thread for a wile now and picked up several good tips for my own swap in progress, so I figure it's time for some pay back.
I had been having nightmares trying to figure out why I couldn't get a decent idle from my stock 98 L-37 with 950pro ecu. my idle problem was very erratic and would sometimes sneek up to near 2500 for no apparant reason, then snap back to near normal.  I knew I didn't have an air leak as I could seat the iac and unplug it and get the motor to chug along at ~500 rpm. I tested and retested for shorts and poor connections to no avail. After 2 weeks of frustration I finally happened to check the voltage of the switched wire to the ecu from the ign switch and noticed a voltage loss of about 1/2 volt from actual batt voltage. it traced back to the ign switch itself. I just put in a new one and now have a good solid idle at 1200.

ymmv,

 I was going over the thread again: it's been about 6 months since I last checked in. Did you ever make it to the dyno. I didn't seem to find
 that post and i was all ears ( all eyes in this case).

Just took a week off and worked on the car.. Took the engine out , redid some engine mounts, powdercoated the valve covers wrinkle red (like a ferrari) and painted the engine cover Gloss black. Also added Supertrapps with 2 Bolt Flanges for easy removal. They made a huge difference and really quieted the car down.... but when I want to be annoying and loud the flanges come off with 2 bolts and Im running pretty much open exhaust.

Cradle was all repainted , tranny was repainted , changed the oil , just little things really.. I had the motor out in 3 hours.. Friend of mine took off the week as well to work on the car...

Got the motor out Monday and it was back in thursday night and all buttoned up by Friday , coolant purged...

a few little things left to do , bleed the slave cylinder , Tidy a few things... other than that she's done... Just waiting for my Wideband  02 from Innovte (LM1) and off we go... Tuned to perfection.

i was told the 4.7l would drop right in and my 4 speed trans would bolt right on and there was no real fabrication needed

Huh

Depends on who you are.   I don't think it's that big a deal, but some aren't qualified to finish.
