Smoking motor update...

[2KWhiteSnake]

Well, the block is chewed up. The #4 cylinder is the worst, but there is a bit of damage on a few more. Lester found fine metal bits in the pan and around the rings which almost feels like sand. Needless to say, MAC will be hearing from me about their longtubes. They won't own up to it, but I think I should be heard.

The block is being shipped to Modular performance the end of the week to be bored and re-sleeved to a 5.0 "big bore" with 304 cubes. It will be honed and installed with Diamond pistons, manley rods, and ARP studs will be added before being line honed. In the interim, Lester will be doing a port/polish/valve job on the heads and installing FR500 cams and valve kit. I also sucked it up and decided to put the FR500 race intake on it (ouch at the price). It should put out anywhere from 425-475 rwhp depending on the tune. We'll be upgrading the fuel pump (focus pumps) and injectors. I guess I decided (with the help of John Pearson, who my wife reluctantly sends hugs and kisses) that it's cheaper to do it now, than down the road.

The block should be back within 15 days, so we should be rolling within a month. I'll keep you OT guys updated as to the progress with some pics. I hate I missed CMP, but I guess that's the way things go sometimes.

Thanks again for all the input!

It'll be a killer piesce when it's done!!!!! :thumbsup: :thumbsup:

Tell April I said hello....then run like hell. :rotf:

[beerkat]

I will keep your motor in my thoughts:D Just have it by June first so you can break it again, I mean break it IN before Roebling.:thumbsup:

[blk04cobra1]

Damn that's a quick turn around...we need to start sending our blocks there...good luck with the build, sounds nice :thumbsup:

[2KWhiteSnake]

Btw.........I just ordered BBK longtubes. Anyone want some used MAC longtubes for a 99-04? I would recommend doing an EGR delete before putting them on. :thumbsup:

Which MAC long tubes did you have? Did you have the HTS coated versions or the ones that are polished ceramic coated? I have heard of a few horror stories from the MAC long tubes in the past... but none here as of recent times.

I've had the TF9902 ceramic long tubes from MAC on my Cobra for two years now with no problems whatsoever. Has never used a drop of oil in 33,000 + miles now and has made in excess of 600 + to the tires for almost half that ;);)

Sorry for your troubles... it will be better once it's back in it's rightful place :)

[2KWhiteSnake]

I had the HTS coating :) Destroyed my block. I ordered ceramic coated BBK's. I hope that will be OK. I'm scared to death. :eek:

[Blown96Snake]

Wow, that motor should be a BLAST on track...well, pretty much anywhere!

Hope things come together quickly, we've been down that road too...make sure you get a really good tune. Its probably one of the most important aspects, IMO of course.

Dave

[2KWhiteSnake]

Yeah, Lester is going to be with the tuner when it's getting done. I've requested that much. :)

Update:

5.0 big bore block should be finished and shipped back to me by the end of the week. I have all parts, FR500 valvetrain, BBK ceramic headers, GT supercar fuel pump, 42lb injectors, MSD window switch (for runner controller on FR500 intake), Billet oil pump gears, Diamond pistons, Manley rods, ARP studs, Cometic gaskets, and ATI super Damper. FR500 intake due to be shipped May 16th. It should be pretty nice once it's all said and done. I'm sure Lester is going to have a blast with it! :eek:

Craig

[beerkat]

I hope that you have a blast with it.

[2KWhiteSnake]

Hey hey Kim,
You got the boat outta the water yet for repairs?

[beerkat]

Yes got the boat out of the water for repairs and have decided that it is time for it to go away.

[2KWhiteSnake]

I hate to hear that, but from what you tell me, it's a very expensive hobby. Especially with fuel prices the way they are.

:thumbsup:

[beerkat]

Well it will give more time to play with the car. We will get back to boating in a few years. Talk to you soon:thumbsup:

[tgentry]

That 5.0 sounds like a fun track engine! Good luck with it. I'm putting my BBK's back on this weekend after doing a r/r on the tranny. I noticed there had been some leakage at the header gasket and a couple bolts were loose so I got the Stage 8 header bolt kit. Cheap insurance.

Yeah, I'm going to need to do that too. Did you do the EGR delete on your headers? I'm terrified about running headers with an EGR anymore.

Craig

[tgentry]

The headers were on there long before I bought the car, and EGR is connected. I don't recall anyone having that problem with BBK's or Hookers, only the Macs.

BTW, ceramic coated is the way to go. Mine were the chrome finish and it was badly pitted and surface rusting in spots. I just got done bead blasting and painting them.

[2KWhiteSnake]

Mine are ceramic coated, but there is a ton of slag (you can see and feel it) on the insides. I hope that ceramic coating will keep that stuff glued to the headers. :eek:

[tgentry]

What would it take to delete the EGR? Can we just remove it or is it somehow monitored by big brother (OBDII)?

[2KWhiteSnake]

Honestly, I don't really know, but I'll ask Lester about it.

[Hazman]

You can do an EGR delete. http://www.need-4-speed.com/nfs.htm has an nice billet EGR block-off plate. You will need to have the car dyno-tuned to adjust for the mod. Check with the guys at http://www.pro-dyno.com/ or leave them a post in their vendor forum here on our site http://www.svtcobraclub.com/forums/forumdisplay.php?f=78

:thumbsup:

[2KWhiteSnake]

Thanks for the links. I'll order the EGR delete tonight. I'm guessing it will fit the FR500 intake also, since the intake is "sorta" a direct bold on.

Craig

[2KWhiteSnake]

Motor is in the car. Should have it "fired up" sometime this week after hooking the computer, etc. up.

4.6 to 5.0 liter Modular with FR500 cams/valve train and FR500 intake. We are hoping to tune it this weekend. Looking for around 425-450 RWHP Naturally aspirated. I'll keep you posted.

Craig

[2KWhiteSnake]

Well, the car was fired up today. Had to put a lightning MAF on it just to get it started. It's running so rich it's having problems running, but it'll idle. I think we're going to have to do some mapping for the 03/04 cobra fuel pump/tank that we put in also. Will be tuned this weekend or first of the week and will have it's first laps at NASA CMP next weekend. I'll keep everyone posted.


Craig

[2KWhiteSnake]

Dyno tune scheduled for Thursday at 1PM with Carolina Performance in Charlotte. Gonna be pushing it for NASA weekend at CMP, but she'll be there come hell or high water. I'll just dump the oil on Thursday night and get the brake system bled. I'll keep you posted Thursday night with Dyno numbers.

Craig

[tgentry]

Good luck. I'm anxious to see what your beastie puts down.

[beerkat]

We will see what happens Saturday at CMP:thumbsup:

[2KWhiteSnake]

Lester actually took it out on the highway today to give it a little break in time. It's running pretty bad, but he managed to keep it running. It only ran well if he slowly eased into the throttle. He said the tuner's going to have his work cut out for him. The FR500 intake runner control actuators are working fine, so I'll be picking it up Thursday AM and heading to the tuners.

Craig

[Big Daddy]

Good luck with it Craig!! Hope the beastie does well and get's the BIG NUMBERS! :D

[2KWhiteSnake]

Thanks Greg! I won't be putting down the power that you are, but if I can break 400rwhp+ on a N/A motor, I'll be happy.

Craig

Craig

Actually that probably is what I'm putting down N/A so if I were you I would be really happy with that!! Good Luck!! :thumbsup:

[2KWhiteSnake]

Aight, picked up the car from Les at 11 this morning and went straight to the dyno. The new motor has but a few miles on it, so there's still a way to go with sealing the rings, etc. Ended up having to put an SCT Big Air 2400 mass air on it, and a makeshift pieced together intake tube for it. We had to piece a bunch of things together because the MM strut tower brace doesn't allow for big intake tubes. Only 355 rwhp on first pull with STOCK intake plumbing and stock MAF (we could see it running out of air at 6000 rpms). With that, we changed to the "pieced together" intake and Big MAF (30HP increase from that alone). As the day went on the car got stronger as it started to break in a little. The FR500 intake LOVES air, and needs plenty of it.

Bottom line:

For now it's at 406 rwhp @ 7200 RPMS
359 lbs Tq from 2800 on (VERY flat torque curve)

I need more air, so I'm going to probably have a custom strut tower brace made so I can get a bigger intake tube under there. We also need another throttle body, as this one isn't cutting it. I'm very happy with making it in the 400's N/A. I'm sure with this weekend of NASA @ CMP it'll be broken in good after a few sessions on track. I'm going back for another tune in August when we make those other changes. It's got a very mild/safe break in tune to get me for a while. A/F 13.5 and timing at 26 degrees overall I think it was.

Btw.....a few technical notes for anyone that might want to get an FR500 intake.

I have the short runners triggered to close at 2500 RPM's (goes to long runners). Then short runners are triggered to open at 4800 RPM until redline of 7500 (and yes, we did run it to 7500) . That setup seems to be the best for most guys running the FR500 as the long runners on the intake stop producing hp about about 5000 rpm's. I use an MSD window switch to control the runner actuators.

I'll be seeing some of you this weekend. For those of you that won't be there, have a safe and wonderful weekend!


Craig

[Big Daddy]

Sounds like you've got the makens of a real nice N/A motor Craig. Take it easy on her this weekend and break her in right. That way you won't be paying for another mistress soon! :thumbsup: ;) :D

[tgentry]

Nice numbers Craig, and I'm sure you'll find some more hp in the fall. Have fun and be safe! :thumbsup:

[2KWhiteSnake]

Thanks,
I was hesitant about running her hard on the dyno, but I didn't have much of a choice. I'm going to do a few easy sessions at first this weekend, but I'm not sure if it'll change much of what I've already done. We ran it to 7500 rpm's all day yesterday, but like many engine builders say..."drive it like you stole it"!

Gonna change the oil and filter out today to see how things look.

Thanks again!

Craig
