1) An NA build is more than I/H/E, plus there are plenty of guys here who have picked up way more than 10/15whp with just I/H/E and a tune 2) I'm talking about speed, that's what a 1/4 mile is, a test of speed. That's where the gears come into play -- an NA car with 4.77 gears, I/H/E, clutch/flywheel, short shifter and a tune and a good driver could keep up in the 1/4
Ahh yeah that's their new dyno -- they used to have 3 sheets on the product page, the one you posted (2004 AP2) did that, but it's an AP2 that historically dynos 15-20hp higher than AP1 cars. Their original dyno did 248whp on a MY00, they dropped that one I see
SC vs Gears, I/H/E, Tune, Clutch, Flywheel, and a GOOD driver. from all those conditions we should take out GOOD driver, since the driver is not a modification, we are assuming both drivers are the same if not it not worth the comparison.
I am not critizaing the NA set I would love to have a prepared engine but I live in Spain and this make it imposible, this was the main reason of why I sold my 2.5L stroker kit. But in term of speed a SC would beat a NA car, Speed means HP and a SC engine always has more HP

Not so, he simply asked if he could build an NA car that would keep up with a SC car. He did not stipulate the extent to which he could build an NA car, and I'm sorry that you don't have the opportunity to do so in Spain, but it is very possible in the US.
One of my friends has a SC'd MY01 that runs 13.5-13.6 at the track. With 4.77 gears alone a decent driver would be running that fast, there are some stock S2000s in the US that run 13.6-13.7. This is just an example of a part that does not increase overall HP but still increases speed.
I am not telling him to get into a dyno contest with a SC'd S2000, but with quality mods (J's Header, 70mm exhaust, standalone tuned ECU, 4.77 gears) he should be able to keep up with a SC'd S2000 at the track.

248 whp in a MY00?? it is hard to belive, the first time that I went to the dyno I had a belt slip and made more than that
This is my NA dyno, power at he engine, this dyno read very low not many stock cars make the anounced HP figures. All this dynos where made on the same dyno and same weather conditions, and almost same NA mods. NA : HKS Ex Toda Header Jracing intake, SC HKS Ex, Toda header and 2.5L Amuse Ex, Toda header, J' Racing intake
NA
Then the SC with belt slippage, 4psi max
Stroker kit, AEM EMS
This dyno is bizzare -- I'm glad that you have made the conversion yourself to US standards, but it still reads high. HKS exhaust and J's Intake don't do anything on a dyno, HKS has even been known to lose hp on a dyno, so basically with just a Toda header (a decent header at best for peak hp) you made 214whp. That's weird. Then you make 314whp at 4psi? Highly unlikely. There are out-of-the-box kits that do that at 7psi, or almost double your boost level.
Oh and I did some reasearch, the original Comptech SC only ran 5psi, they upped it to 7psi to keep up with Vortech's kit after it came out. So on 5psi they made 248whp, and you are doing 314whp on 4psi. There is probably some dyno discrepency (as there are between any two dynos), but this is a large gap to fill. Either way, if you want to tell people that it's impossible for an NA car to be as fast as yours, then you should go to the track and put down some numbers.
it is not WHP figure it is HP figures. all were made on the same dyno. regarding the HKS I have some friends who pick up some hp with the HKS, lossing power with the HKs is almost a myth, all started many years ago when one onwer "lost hp with the HKS, but I have not seen more dynos proving it. I know that HKS do not make power like amuse o j racing.
Comptech runs 5.5 psi and the aftercooler runs 5 psi. With higher psi the waranty on the SC is void
BTW I do not have a SC right now, I am an Ex turbo. At track is more important the driver and the alignment seting and tires than HPs. When I refering track I and taling about road track not 1/4 mile track.
just to add some fuel to the off topic fire. My friend icemans2k02 has a Vortech SC Ap1. Before I sold my car I was able to hang with him from a roll. I had all the mods in my sig + ACT clutch and comptech flywheel. I believe the gears really helped. I would jump out by a car off the start, then he would slowly come back and pull me by a car. To his defense I think he said he was only boosting 6#'s due to belt slippage. If we ever raced at the track(1/4 mile) it would be a drivers race.
OK cool, if it's HP at the crank then that makes sense. I was told by quite a few people in FI forum that the Comptech SC kit was upped to 7psi a little while ago, dunno if it's just a rumor or not. I know the HKS can't make much hp, and I've seen a couple dynos (one from a guy in TX, one from a guy in LA) that lost power with the HKS, but could be due to improper install or something.
Thanks for clearing it up redlineF22c1, we'll call it a driver's race then.
