Front set up I have is available with 13" rotor meant to work with OEM A mold. Rear set up I have (12.8" rotor) fits inside 11" wide A mold.

Okay, great. Thanks Yun! I'll get with you and see what all the options are.

It required some massaging to make it work including parking brake cable bracket under the car being cut/welded by 3/4" and having to shave outboard brake pad by 3/16" and adding 3/16" thick aluminum piece to shim inboard pad. Otherwise, this was the simplest parking brake solution I found and it works!


Thanks I will look into it and start saving now :-D

Hey Yun,

I just got off the phone with Kevin from Revolution Brakes. After your issue in 2013 the brackets were corrected with the next order. The kits from Revolution Brakes are good to go now and direct bolt on with no modifications. Great news and I'm in! He said they can also powdercoat colors for those that don't want the Wilwood black for some bling.

Thanks again!

That is good news because I wanted the same red calipers as I have up front. Now to save my pennies

That's great! I'm glad to hear my feedback to Revolution Brakes actually made them improve the product.
Let me know if I can help as you move forward.

Like GC, I have to save those pennies. Kevin sends his regards and wishes they could have fixed your issue; but he knew you are an Engineer. Like -=Jeff=- said, no mods should have to be done to a specific application kit. You are a pioneer. My problem is I think I might want to put stock wheels back on (for what reason, not sure other than to track?) so very limited and this is the best option I have seen so far. Thanks again! :saluting:

It was long day for sure. My whole body is aching from wrestling with 700 lbs of motor and 100 lbs transmission...

She'll be running come Saturday.

10/17/2015 update:

Started with cleaning under the car. Took advantage of Dempsey's lift and Touched up areas I can't normally get to.
Finished installing injector housings, and with Dempsey joining me later, coils, plenum, etc...
http://i658.photobucket.com/albums/u...psubtbangd.jpg

Oil pressure is 45 psi at operating temp at idle and no strange noise from the motor.
On the way home car was missing most likely due to plug wires being plugged into wrong coil terminal. I was too tired and in a hurry.
Ordered new set of plug wires and spark plugs.
Can't believe I had to do this twice but it's done and behind me.
Great big thanks to Dempsey, Phil, Rich and all WAZOO gang for incredible help!

Looks awesome Yun and glad to hear the good news. Like Lee said, can't wait to see the dyno results on a 380. On another note, thanks for the info on the Revolution Brakes and I should receive them next week or so.

Thanks Craig. Once I sort out spark plugs and wires, I need to do some data acquisition and have Marc touch it up.
If you run into any snag with the brakes, call me.

Finally installed new NGK iridium plugs and replaced spark plug wires. I had crossed #3 and #5 wires-explains why she was missing bad returning home from Dempsey's.
All's great now.

Congratulations and great news Yun! :cheers: You reminded me I need to take a look at the plugs in this new to me 95.

Good question for all. For me, just the bigger brakes and headers and I'm stopping........ha, ha. Seriously, I'm going to slow down on mods and concentrating to retirement savings.

Re: Second time for Secondchance
 
Drove into work today. Even with .425" intake cams, when running right, LT5 runs really smooth. I didn't go too crazy and kept it below 4000 rpm.

Check out that oil pressure!
http://i658.photobucket.com/albums/u...psxjhjpyud.jpg

When oil temp is at 197 the gauge says 38 psi. This reading is with Mobil 1, 10-30.

Probably this is no big deal to most. However, having endured not knowing why my pressure was like 12 psi at idle, and more importantly, wondering if the low pressure was damaging the motor for 8 months, this is a big deal for me.

Lookin good Yun!!!!!.....break it in right and bring it back to me to do the oil change and oil analysis !!!;)

For sure! How about check for detonation per Marc's procedure using Tech 1 and some data acquisition every 1000 rpm so that I can turn to Marc to touch up my PROM?

rkreigh 10-28-2015 07:54 AM

Re: Second time for Secondchance
 
I think it would also be cool to run some traces with EASE and send them off to Marc if you are going to do a chip reburn

I have it on an old laptop if you'd like to give that a try

I would before you dyno it and even get a wide band 02 installed to see what WOT AF ratio is doing for you. they are cheap!!

we should do a wazzooo tune on this bad boy.

If we pool our $$ we can afford the gear and then learn together some tweaking

fun winter project!!!

congrats on getting the "black beast from the east" back on the road and help usher in the era of a low $$ LT5 builds!! the 380 is a fantastic combo using the affordable offset stock crank and I think with solid intake and injector housing porting this combo will see over 500 at the tire which is a really good goal.

LPE LSV 36k (includes brakes and B&B, headers ect...) - 508 hp

Secondchance stroker lop a HUGE chunk off that price tag. - 500+ HP

I love my LSV but I sure wouldn't want to pay for it that build!!! (thanks Larry RIP)

I'm very impressed with what the Wazzooo boys have done

along the lines of poor mans power (pardon the hi jack)

I'll send some pics of my lastest "poor mans toy"

a TT 4.8 LS iron block with forged wiseco pistons, gen IV stock floating pin rods, stock crank, head studs, twin t04 turbos, 127 lb injectors, haltech ECM target is 1k hp at the tire without twisting it up over 6500

ok, r u sitting down short block cost ($1230 at lloyds) bought a used engine for $2300 with the turbos & stuff and freshened it up (had a bent rod and piston skirt issue). guy was nice enough to give me another 4.8 too!! I'll be building that one next for a bit more lunati forged 4.0 crank, rods, and wiseco pistons with AFR 225 heads to update the Z06 TTix TT (800 at the tire will only scare you for so long, need another 200, it's chasing the dragon I know but I like dragon rides :)

very happy with the results and cost. I hope to put this beast in a 68 vert vette as the current 350 is a bit below my clearly jaded standards (anything less than 400 at the tire feels slow now :<)

boostamuv!! maybe we can do a Wazoo TT ZR-1 someday. if I can talk robert into welding up those stock manifolds, some nice ball bearing billet wheel turbos LPE style, and a megasquirt doing "secondary only control" I'd really also like to do a cross ram intake with two fuel rails, one for pump gas and then the megasquirt controlling a separate fuel system to bring on some big doggie 80 lbs injectors running meth.

also like to go coil on plug at the same time and the megasquirt can handle the ignition chores with just a crank trigger. I'll live without the fuel range estimates and the security system :> I think the raptor megasquirt thing may have died off but I might be able to talk Phil out of his prototype or at least get corey to do me another one :>

I hope to do this someday right after I sell both kidneys and an arm :o

Re: Second time for Secondchance
 
The Megasquirt guys (www.diyautotune.com) are local (Suwanee, GA) and I hear they are very close to offering engine management computers for the LT-5. They told me recently they just need to test the last firmware version. As you say, it can control secondary butterflies/injectors, coil-on-plugs and more. That's pretty great news, not only for folks wanting to modify, but also considering the lack of GM computers available if one goes bad.

it is the $2000+ price that bugs me though.. if ti eliminated the ICM or had option to run something other than our ICM for $2000+ then that different

our ECMS can still be repaired for way less than the cost for the new ECM

Hey, Ron,

Now that #256 is running again, I'll be at Cars and Coffee this Saturday. We can talk about best option to record data and get it off to Marc.

Amount of money saved - no doubt! Holding and oiling pistons and sliding them into each sleeves - priceless!

I had mine repaired and it was totally worth it...but the guy who did the repairs told me the ZR-1 ECMs come in two type - those that failed and those that are going to fail. He also said he has about a 2/3 success rate with repairs. So going with his logic, buy a "known good" ECM for $800 that will fail at some point, or roll the dice on a repair for under $400. You could easily be out $1200 trying to fix an ECM problem, and then STILL have a broken car. Megasquirt starts looking a lot better.

I agree with Jeff 2k is too harsh. It has more flexibility but the price point bugs me as well.

rkreigh 10-29-2015 03:31 PM

Re: Second time for Secondchance
 
yes, we are paying for the R&D there as the LS megasquirt is 1200 or less with a plug and play harness.

the after market ECM capabilties that is opens up are pretty cool though.

the old ECM is the ZR-1 was a bit of a bastard child and very slow in processing power compared to the new stuff.

the MS without the wiring is only a few hundred bucks.

I'd like to try it JUST controlling the secondaries with a modified memcal and I think that would work pretty cool!

LPE did that on the TT cars very successfully with the aussie LINC stuff.

Graham, you out there!
