Jim... relish in the the glory of the car.. stop the put downs to make yourself seem more reliant or helpful here, because to me, its just a bunch of noise.
i have a bunch of serious racers here that have been at the top of their game for many years LAUGHING hysterically at what YOU in particular are saying.
i cant tell you what they are saying, but trust me.. just go away Jim.... quite frankly, you sound like an idiot

Default Racing the 928 at Laguna Seca today pics

These look like small bush league cars Jim??

even that Evo came all the way up from LA to run with us. full pro support. the mustangs ... same thing

on the pole for class , and 4th overall..... with a few cup cars behind.

the best part of this, and you and greg dont get it.... is this is the MOST fun you can have with your clothes on! And ive done WAY more than most anyone I know or have met, Ill gurantee you that.

Happy to be the idiot and glad your "peers" find it laughable..... given that this entire thread is a JOKE !! Did you share some of your manifold design theories with them Last I looked Carl's intake was just 8 holes what does that matter ?

Jim, just stop acting like one, oK???

Look at what you wrote... these are the best guys in the business . why wouldnt they crack up (in a "is this idiot for real?" kind of way) over what you said...and yes, i asked about the intake. they are all behind it and have fabricators all over.
yes , its expensive. heard about some frankenstein projects that did yeild great gains. its not impossible. I dont know jim, it might not work. im not the expert here, but ive seen some results out of lesser engines and so have they.

carls intake is just 8 holes... perfect amount! .... we are talking about mounting something to them, right Jim???

How you can draw the line from that to our engines and saying a new manifold will fix everything is beyond comprehension. The text in green: Um NO! It is not stock!
the larger intake valves was what ford did. the only thing that is there that is much better than a GT for example is the cam and its higher lift by 3mm.
but also keep in mind, this is getting 450rwhp out of a 5 liter. if at the top of the RPM range if we take the cam and 1 point of compression out of the picture, it points to all intake. and quite possibly, a little of the head work. but still, even half of those gains are probably in the intake .

again, all im saying is that the intake is 30hp for the stock S4 and 60hp for more of a modified 928, (or stroker). nothing more than that. its not crazy talk here. I believe as we have seen even with Jim's GT, that a bolt on intake can make it happen AND quite frankly, probalby more power than im estimating.

If you can say the oversized airflow meter and dual throttle bodies are just a "hole" and not relevant to the performance of the Carbon Intake.....then Carl's intake is just 8 holes too.... But I still keep coming back to the Salsbury 4850 D for the plenum. Big Mustang boss 302 throttle body , switch to MAP instead of the mass airflow to eliminate that restriction that YOU already pointed out....
I have no doubt that YOUR engine desperately needs more air. Never have doubted that. Also needs more camshaft since as displacement increases the same camshaft effectively is more MILD. What is radical in a 2 liter 911 is a tractor cam in a 3.6....

sorry, i should have been more clear. the "holes" for the TB and lower manifold are critial for reduction of pressure drops, but the intake is the restrictive element and there is a lot of gain to be made there. when you lose the MAF and can do things as run ITBs, the power is HUGE. we are putting a box around that, to make it more production component controled as far as spark and fuel..... its a proven way to increase power in a big way.
a 3.5" MAF , getting expanded to a 4" MAF using the Homedepot parts as mark did, AND a bigger TB , like 3.7 to 4" as well, does a little, but not much as Mark saw as well. BUT , when he put that intake, it was SHAZAM!!!! 100hp!

bottom line, i dont want to argue with you ... its my theory that the intake will give a bunch of gains in conjuction with a bigger maf and TB,but its not a requirement.... those are easy things to make larger.

OK you are first in your class...aren't there like 50 classes in a typical SCCA event ? Fourth overall in your group race of what 8-10 classes of cars many admittedly lower performance than yours. So exactly how many cars are in YOUR class ?? Lets see how big that pond really is

Try to remember that Mark is more concerned about horsepower over torque. I personally think that the Salsbury 4850 D plenum would be too small for Mark's race engine.....even given his smallish camshafts.

Many times the "pond" was over 25 cars in class. we had many races with over 40 to 50 cars ...ITE was the most popular class. anything goes on DOTs.
you know less than nothing about it Jim... you are now just looking a little green
With the economy what it is today or other factors. the car count is down like nothing ive seen in 15 years. normal class size for ITE was between 10 and 15 cars if i was to get an average. but that was for the first 10 years. I bailed when this changed and then started getting frustrated with classes, and went to the American V8 class, and when that wasnt full, went GT2. last 4 seasons have been funny with car counts. but the good news, i race with the entire group 3 which is the fastest group and has stock cars, cup cars, etc.. im always in the mix with the front pack and plenty of wheel to wheel racing to make it real fun

well greg, as ive said many time, and this indisputable. right from newton himself.
acceleration is proportional to HP, so yes, its average hp i care about

acceleration = power/(mass x velocity)

this means that basically power is what determines acceleration at any speed.

torque? do you even know what torque is greg? torque at the rear wheels after the gear box multiplication or engine torque. if its engine torque, you are way way off base. it would be great for you to understand this, before making judgment of what i want or what anyone wants as far as a HP /torque curve .
just say'in

So what about tomorrow ?? how many cars in YOUR class and your race ?? I could care less about last year or ten years ago. Also with so many alternative race and DE groups putting on events SCCA has a lot of competition. Congratulations on going 4 seconds a lap faster than you have ever done...that is a HUGE delta ! Has to make you rethink your decision NOT to buy tires since 2001....or is there a special class for cars on worn heat cycled out tires ??
Cool thing about SCCA is there are so many classes that nearly everyone gets a trophy....a bit like T-ball for the kids.
But you are right I do get confused, when you say "ITE anything goes on DOT tires " ....how does anyone cheat ??

It's not necessary to attack everything I say, Mark.

Just pointing out, in my opinion, the Salisbury plenum is too small, for your needs....but perhaps you've studied this more than I have.

BTW....Jim's thought about SCCA being like t-ball for kids, where everyone gets a trophy, pretty much hits the nail squarely on the head.
