Thanks for the link. I'll call them and check it out.

This is impressive! "About" how much did this H/C set up cost you?

Patrick G

iTrader: (14)

It was more than a little and less than too much. PM geoff and he can work you up a quote based on your needs and specs. The parts themselves aren't too expensive, but the labor and dyno-tuning can add a lot to the bill if you don't do them yourself. Thunder plans on selling a complete mail order package including pcm tuning if you're interested.

Mill our logo off the front and drill it, mill it, etc. (carefully) to accept a factory freeze plug!!

yes thats true but its not as cut and dry. the real power of this package are the heads and they were not cheap, they arent box stock 205's, they been heavily ported by someone who knows what there doing as evident by the rediculous flow numbers.

sure you can mimic patricks combination with out the box 205's but i doubt you'll reach the full potential like he did.

WTF?! JRP I think you are confused with the SAM heads that Patrick was initially plannig to run. After much discussion it was decided to run the AFR 205's as this would be a head that we could more easily sell instead of some one-off special that wouldn't be easy to reproduce. These heads are out of the box 205's that have been milled .030". Other than the flat milling these are the exact heads that AFR sells to anyone else. There is noting unusual or special about Patrick's heads.

Also we are planning in the next week or so to put just the cam in another car that has the same set of boltons as Patrick's car minus the cylinder heads. This will show the potential of just the cam. Right now this other car is basically making the same power as Patrick's with the boltons. This other car also has the stock manifolds, cats, and y-pipe.

guess i missed the part where he changed from the SAM head that he posted earlier. THAT was a killer set.

I don't know about all that.
Some people like the lope. I love it.
I already pass emissions without AIR, EGR, or cats with a large cam.
Cheaper? How in the HECK do you figure cheaper by half?
Economical? How so? Gas mileage??
A properly done big cam high stall car WILL run better times.
It doesn't sound liek you really know what you are talking about. Especially if you think it will run 12.0, and even more so if you think that 12.0 would be a good time for a heads/cam car and would make a big cam/stall driver cry.



Not to take anything away from what you've done. That would be one HELL of a sleeper. Would be very, very fun to have in it's own way.

I'd be interested to find out how you pass emissions with a large cam and no cats. That is some magic!

As far as ETs, 12.0s are easy, in fact 11.0s are certainly a possiblity with more gear and better traction. Economical yes, but only from a fuel economy standpoint. Getting 395 rwhp within the contraints of stock exhaust and stock driveability cost twice as much as doing it cam only...but for me the extra investment was worth the lack of headaches the other way often brings. I like how reliable and quiet stock cars are. Don't fault me for trying to keep it that way but increasing power by a large margin. Like I said in the original post, I don't expect this approach to be everyone's cup of tea, I just wanted to lay out a new way of making power with fewer downsides than most modified cars face.

blkZ28spt

OBDII plug in diagnostics. Haven't you heard? It's very common. Little LS1 edit can go a long way towards passing emissions.

I didn't mean to say it would only run 12.0's, I am sure it can do better than that. I was actually using the fact that he seemed to think only 12.0 against him. This is assuming you can drive.

I am sure it cost more to do it this way, unfortuately the guy I was responding too didn't get that. You are right, it isn't everyone's cup of tea. Neither is a 4k stall converter with a 237/242 cam in a daily driver. For what you wanted, you got a helluva setup there.

Patrick G

iTrader: (14)

Yowza! Now THAT'S a manly cam for a daily driver.

blkZ28spt

I love it. Just my cup of tea. I'd love to have something set up like yours as well, though. Would be even more fun if it had some forged goodies, better fuel system and a larger shot of n20.

I'd say I'm a fan of going ***** out in whatever direction you take with a car. Whatever you want it to do, go all out doing it. I want mine to flat out haul *** while sounding like a pro stock dragster. If I didn't do that it'd be a total sleeper, I kinda like the sleeper aspect. That's why my car doesn't have any badges on it and looks like a V6 to a lot of people who don't know much. Check link to cardomain in sig. Little over half the voters say they'd think it's a V6 if they saw it parked.

Same as the OMC lobe?

Intake lobe is the super fast OMC lobe. Check your PM.

what was the head gasket thickness?static compression ratio?

Patrick G

iTrader: (14)

Thunder used the GM MLS gasket. Combustion chamber cc volume was 60cc. Pistons were not flycut. Static compression comes out to 11.0:1 and dynamic compression is 8.53:1 based on some reliable programs (thank J-Rod). This is one of the reasons why the new motor's torque is higher at every point of the dyno vs. stock. Even at 800 rpm in 6th gear, it feels stronger than stock. With higher compression, better flowing heads, and ports with higher air speed, I shouldn't be surprised the street manners are even better than stock.

Using the stock exhaust manifolds with RANDOM TECH cats and larger diameter Y pipe might free up some power. BASSINI also makes a larger diameter Y pipe with cats package that will fit OEM manifold. The cats are welded in the stock location with both of these kits.

That small OEM exhaust pipe welded at exit of the OEM cats looks very restrictive to me.
