Hello Everyone!

Hello Everyone!
Hey guys, might be surprised to see me over here. I'm planning on a few new mods to the Goat and I would like Mike to tune it.
Backstory:
My car was tuned and still is running on the tune from Precision. It runs great, I am happy with it. Jeff has been great. The only issue I have is that it was strictly tuned on the dyno at WOT. A few street sessions were done when I had some type of HPT recorder with me driving, but nothing like the service that proxses offers. Also, my dyno sheet is not smooth curves at all such as Brents or Waynes.
So you might be wondering why I didn't have Proxses tune my car to begin with? Well, I was relatively new to BuckeyeGoats and didn't know anyone from going to meets when I did all the work to my car. I had done a lot of reading about tuning on the big forum, and there were multiple horror stories about peoples friends and what not tuning their cars. Because of this, I just felt more comfortable going to a shop for the work. I didn't know the true capabilities of Mr. Proxses here.

So, questions for Mike.
Jeff had me drill a small hole in my TB for idle issues. I did it because I can easily weld the hole shut and grind smooth. Not a big deal to me. Would you want the TB hole closed? Also my cam is a 239/242 .651 .610 112LSA. Right now it idles at 1000. I would like to get it down to 875-900. Possible?
My car dyno'd 445/403 and it had an intake leak in the intake tube. Once I fixed that it felt stronger. I had a real time with it because the leak was after the MAF and threw the car into safety mode and all kinds of stuff.
If I port the FAST and throw on a Mezeire Electric water pump do you think 460/420 is possible? I might do heads also, but I might save that for another year.
I probably should have talked to proxses before posting this thread, but I figure its a good conversation and activity on the new forum (which BTW is Bad ass)
Have at it fellas.

Oh, and the end result I am looking for out of the car is 490/440 with heads somewhere down the road. Thats why I went with the S2 cam was with the goal of adding heads. Any other major stuff I am leaving out let me know!

Welcome!!
I have no issue with performing the tune. As for the TB, you can weld it up if you like, or we can tune it as is. Brent's is NOT drilled, but Wayne's IS. It actually does not matter all that much. Drilling is just a cheap fast way instead of calculating and adjusting for the changes in airflow.

We will be using that little box a bunch during the tuning process, but the difference is that I will be in the car with a laptop, and actively monitor everything. 8)

Idle will be pretty harsh and lopey down there. I like it in the 920-940 range, but you are the customer, and we can shoot for the lower idle. It will sound crazy down there, which would be quite COOL.

Porting the FAST will provide a nice bump in power, but if you want those kind of numbers, you really need GOOD heads. I would recommend a purpose built casting like the AFR or Trickflow offerings. 205 would work for your displacement. I don't think the CNC'd factory castings can keep up in this case. 490 is a bunch of NA stock cube power, and you need the most efficient parts to get there.

Oh, and with the electric water pump, if you don't have an underdrive pulley, I suggest you get one.

And do you have a digital copy of the dyno sheet? I'd like a look.

8) I am one step closer to a Proxses tune! Woot!
Let me see if I can cover everything...I love planning changes to the Goat! :D

Leaving the hole would be fine, or for experimental we could tape it, see how it does, and try it both ways. Might discover some pros/cons from each method. It really doesn't matter to me.
The lower idle does sound pretty sick when it dips down, I'm not shooting for any certain number but lower with a nasty sound would be cool. At 1000 it idles very smooth.
As far as the heads, I am definitely going with an aftermarket casting. I really like the idea of a 215 cc head and 11.8 - 12.0 compression. Edelbrock heads are #1 on my list as I can run my scorpion roller rockers with no issues. Im not a fan of changing the stock valve angle drastically like the ETP heads or TFS do. AFR or Edelbrock are what I am holding out for, and their price tag is why I am waiting!
I have an ASP underdrive pulley installed. 1 7/8" kooks. With electric pump, heads, and porting the FAST it would be a complete "everything but the kitchen sink thrown at it" n/a build on stock cubes.
I also have 45# injectors currently installed.

As far as the dyno graph, I can upload it Monday night once I am back to my apartment with a scanner.

OH, and I forgot! I have a major issue with the car right now. When I rev it in neutral it revs up fine, then hangs and idles at 1800 rpm. I can then put it in gear, slip out the clutch ever so gently and it goes right back down to idle. I have not taken off the T/B to see if there is any build up, but there doesn't seem to be an issue anywhere except free revving with no load. No check engine lights or anything like that. Weird.

Sounds fine for the TB experimentation. And this ties into the hanging idle. Most likely this is from the idle airflow tables being off.

As far as I know the TFS don't require special valvetrain. They shift the valve angle to improve flow and plug location, then adjust the valvetrain geometry to adapt stock type rockers. I think the only thing you need to do would be to check pushrod length, which should be done with any head change.

I'll wait to see the dyno for more.

I am getting these very soon

Great deal on them from Speed Inc. I'll just swap my springs over since they only have 1600 miles.
Now the question is what gaskets? Cometic? Should I have the heads milled or run the thinner gasket? I think I am going with the Cadillac lifters and ARP head bolts. Might not be able to purchase and install everything until summer time though. We shall see.

Odd that the hanging idle is from the tables, I would have thought it would shown up sooner. Oh well. She is going to be a different beast by the end of 09 anyways :twisted:

Really, you want those heads?.... You know that for a little more money, you can buy some AFR's or Trick Flows that really outflow those heads! Edelbrock makes some nice quality heads, but they never really flow all that great in my opinion.

How much do the factory unported 243's flow?

I would recommend calling up the guys at Total Engine Airflow and talking with them. Tell them your goals, and see what they have to say.
The Edelbrocks don't seam to be able to support the airflow needed for your power goals. I would give the TFS 215's a second look. You can run the rockers you currently have. But call TEA.

The Edelbrocks flow right with the AFR 205's until the top end. They make their peak torque 600 rpm's sooner.
Here is the AFR 205 numbers:

AFR
* Name AFR LS2 Mongoose
* PN 1510
* Price $2,479.99
* Combustion Chamber size 66 cc
* Intake Port Size 205 cc
* Valve Sizes (intake/exhaust) 2.02/1.60 inches
* Horsepower at 3,000 rpm 234.3
* Torque at 3,000 rpm 410.1
* Peak Horsepower 547.1 @ 6,400 rpm
* Peak Torque 479.5 @ 5,500

Here is the Edelbrock 205's

PN 61969
Price $2,399.99
Combustion Chamber size 65cc
Intake Port Size 202cc
Valve Sizes (intake/exhaust) 2.02/1.57 inches
Horsepower at 3,000 rpm 236.5
Torque at 3,000 rpm 414.1
Peak Horsepower 535.9 @ 6,700 rpm
Peak Torque 479.6 @ 4,900 rpm

These numbers are from: http://www.gmhightechperformance.com/tech/0701htp_cylinder_heads/index.html

The Edelbrocks I have put a deposit on are partially cnc'd but 215 cc. I might be sacrificing 10 or so rwhp on the top end, but I'm getting the heads for $1500 shipped assembled. Thats really all I want to spend. If money wasn't an issue I would go with TFS or ETP 215's, but they are nearly an extra thousand.
490 was my lofty goal, what I am really looking for is more torque out of this big cam, I think these will help me get some more torque under the curve and stay within my head budget. $2500 for heads on a strictly street car would be to much sacrifice for me with all my other bills. :oops:

I do not like heads being compared with dyno numbers only. There are to many variables to take into consideration, like cam size, cubic inch, intake, humidity, temperature, engine temperature, etc, etc.... Plus magazines/shops can fudge numbers based on sponsor ship.... Show me some hard numbers!

I am not saying that the Edelbrock's are a bad head. I am just saying that there is much better choices out there.... Heck you could also send your stock 243's to TEA and have them ported for less money and better airfow.

I can buy these for $1500, then install the new .600 springs on my 243's and sell them for $500 or so for a total investment of $1000. Is there something that can beat them for 1k? Because from my looking around a great port job to beat those numbers is around 1500 using my own heads. I'm not debating that better heads can be purchased, but for my application these seem to fit.

I believe with the cold weather I had too much time to be inside thinking about heads. Instead of jumping on a decent deal and ending up with the wrong stuff, I'm going to put the heads on the backburner. I need to tie up some loose ends under the hood (running new fuel lines and a few things) that are going to add up $ quickly, and I'm not wanting to eat ramen all year in 09. :lol: :lol:
Still might get the FAST ported and add the mezeire over the winter months, then a proxses tune come april or so. Im heading in the right direction :D

I missed alot on this form.. HI ROB!!!!

Looks like ur getting ready to really open up ur cvar with the heads and the P&P FAST.

Too many mods and not enough cash.
I just bought some pedders parts.
Coilovers, and all the bushings I need for the front, and end links.
Need a set of sway bars then I can install everything up front at once.
And uhhh, that purchase kinda dented the motor fund. :cry:
I would like to get my Fast ported, new fuel lines (not liking the rubber ones I ran last year) and a proxses tune for this year. I'm dumb for even going that far with the way things are looking at work!

Well, I think you will love the coilovers. I have the Xa set on the way, can't wait!!
We can talk about future plans during the tuning session.

once you get these parts, u gonna take the car to the track any? :) would be cool to see what times u get with all these mods.
