Just Trying to Keep Up with Croc

Recommended Posts

I just know that if I make one more upgrade I'll be able to keep up with Croc at the track this year.

 

This times it's high lift Camshafts, top secret valve springs and an upgraded MBE ECU! 13.2 mm of lift should get me over 300 HP (can't let Croc know how much over), 9,500 RPM, plus a broader torque band. I got the toys from SBD Motorsports

 

The MBE9A4 ECU will work much better with the Geartronics paddle shift kit than the Cosworth MBE ECU (aka an old school 992 ECU)

Ooooh, This is going to be a fun season. I just heard from Jeff who is having some work done too. I need to grow some balls to be able to keep up with you big dogs. :cheers:

 

My car is on tap to get some new dedion ears, new slicks, a new clutch, Cambelt Change and a new master cylinder. All preventative maintence as the car is now 13 years old.

9500rpm?!!!!:eek: This is the kit that gets you to about 310hp. Who is going to machine your head for the extra cam lobe clearance?

 

Alas, I am not doing anything like that - just trying to drive faster - although there is one aerodynamic and styling enhancement underway that I will have for this driving season, it does not add horsepower. Consider it the automotive equivalent of "Just For Men." :jester:

 

More horsepower will come with my next seven which is many many years away given I want to restore my old race cars first and bring them to the US to drive properly since I have held them 20 years in storage.:nopity:

 

Anyway, the fastest drivers are not at my NJMP track, they are in the Dominican Republic. I have the emotional scars of having been a passenger from Santo Domingo to La Romana in some Hyundai minivan on the redline in 5th gear at 110mph with a bad wheel vibration. Tom texted me the Spanish to slow down and the driver offerred me a beer in response and then had one himself. :svengo:

I have added a new starter: that should be worth a coupla seconds a lap! And, I replaced the batterry in my GoPro mic, again, another coupla seconds.

 

Karl: 9500 RPM's, wow, I really cant wait to hear that sound!

 

Croc: Dont forget your new on-track Garaj Mahal, and restored vintage racing Mustang, when tallying your racing oriented toys. I think Karl has a ways to go to be up there with you,and that's before counting your Aussie racing toys.

 

Taxi story: LMFAO. Tom to the rescue!

Steve at SBD recommends using a die grinder to modify the head to get the clearance for the taller cam lobes. Wish me luck!

 

Yes, this is going to be a fun season at NJMP!

:eek: Are you nucking futs? Forgive my reaction but I am not sure this is a good idea... You have a precision machined engine component that you are going to just modify by laying into it with a grinder? How will you know you have taken enough off by just looking at it? Or do you have to put it all back together to turn over by hand to make sure it is not rubbing? I think you want a pro to do this for you using the clearance specs of the cam that SBD should have given you.

Wow Karl, you sure sucked Mike right in with that one. :rofl::rofl::rofl: Croc must still be really shook up from that Taxi ride, he's usually not that gullible.

 

Tom

 

Tom, I was serious. The cam lobes may (won't know till we lay them in there) be very slightly too tall to clear the head housing. We are not talking about anything inside the combustion chamber, just the head casting. Anyway, we may end up with the CNC file from SBD to make the job tidy. Just depends on how much material needs to come off, if any.

 

The way this is done is to lay the camshafts in the head and rotate them by hand to see what needs to be modified. Barbaric I know, but SBD assures me this is no problem. They should know better than me.

 

The before dyno run is set up for Friday morning.

 

Anyway, what was going on in the DR? It's a crazy (in a fun way) place to party!

Karl,

I guess you are doing this with the head still on the block. How are you going to

keep the metal chips and metal dust from filling up the valves seats and then dropping it down the bores and or getting stuff hung up on the valves on start up. Won't be very good for the piston skirts and bores.

Sounds like it should be done on a CNC machine, and then put the head in the hot tank for a proper clean up.

Good Luck, Steve

Yeah, it seems to be the place to go for the New Jersey crowd. (Senator Mendendez seems to have made quite a few trips there to sample the local talent) :lurk: FBI is now investigating. Croc be careful the Fed are involved. :jester:

Steve,

 

Thanks for the advice, I wondered about the metal chips. My mechanic has a machine shop that can do the job right.

Power, power power! Is that all you think about??

All I have done is cleaned and restained the seats. Repainted thr front suspension and frame. Remove the play in the steering rack. Instaled new ball joints up and down. Painted the springs painted and cleaned the brakes. I replaced the clutch and had the T-9 rebuilt then put the engine and trans went back in car on Sunday. The electric, plumbing and headers were hooked up as of last night. Collector and exhaust went on tonight. New stainless steel mesh going into fenders vents and then it’s off for alignment and a diff seal replacement. It should be road ready (but not faster) by next weekend. J

Me too. I always enjoy being out in front, or on track day it is also a blast to pass a $250.00 Porsche, ZO6, or a Viper. On a fast track there is only one way to attack these guys....mo power.....plus a lighter car. I like 550 ftlb of torque. It Feels real good.

That sounds much better. Stop winding me up....:dupe: I am a little delicate this week. I even managed to roll my golf cart yesterday when I cornered it just a leetle too fast.... :o

 

I have faith that even with more monster power under your right foot I can use my awesome rear end to give me an advantage in corners to beat you. :p Plus my Caterham is the only one to get airborne on the back straight thanks to the superior aerodynamic shape of its driver....oh wait...:ack:

Had the car on the Dyno Dynamics 450, no wonder I can't keep up with Croc. The Map from Cosworth obviously needs some work. Air:Fuel ratios seem out of whack. Not so close to the Cosworth rated HP. With any luck, the new cams and a good ECU programming should improve things.

Ahhh, the joys of the dyno "Grand Prix". Your Duratec is making abt 75 more hp than my Duratec. So ya got something for all your money. And, normally aspirated cars show smaller and smaller returns as hp goes up for $ spent. If ya really want to go big, do a turbo!!! You have that "large" SV engine bay. Much bigger bang for the hp buck w/forced induction.

 

I am very impressed with how (relatively) flat your curves are between 6-8.5K rpm's. With your 6 sp transmission, you should be able to stay in that large, predictable sweet spot everywhere on the track. So the engine looks to be very ''driveable". That is a tuning goal even more than peak hp.

 

Also big diff between crank hp and rear wheel (aka, real world). Also big diff between what after markets suppliers promise vs. reality. And, every dyno is different. Some are much more conservative than others.

Karl, you have more that enough car to run with Croc, you just aren't as crazy as he is. :jester: If you're trying to stay with Kitcat and Croc, you just need to rewire your brain so that you have no fear. Just look at their faces after a session, they are possessed.
