Toddnos's JWT pocharger and heat shield

[toddnos]

I highly doubt that your intake mods have improved airflow so much as to bring your rwhp up to the advertised crank power.

The closest I've seen rwhp to advertised crank is on my coupe with the JWT flywheel, k&n drop-in filter and blox spacer. That was 273 (advertised at 298).

I usually like intakes for two main purposes. Throttle response and to hear the engine. I think the intake (heads up) can definitely be improved, but I don't think JWT, Stillen, or any of the other manufacturers have really figured it out.

i never claimed specific numbers, but i was thinking near 250 hp.thats what i believe the car to be rated at, and i believe my mods have brought my to the wheel Hp to that number.

like i said i have had plenty of cars strapped to the dyno....i believ what i say to be true, and like i said when i started this conversation it was one mans opinion,....

now keep the Honda Tech style "joke of the day" commments out ,and the constructive discussion going...thanks!

Dude, there is a 15% drivetrain loss (the GTR has 10% loss) of power between crank and wheels. if you have 280 stock (with the 6MT) then you are at 238 rwhp. If you have the revup you are pushing 298 that would be 253 rwhp.

if you have the 5AT you are at 221 or 238 with the revup.

dude like i said...221 plus the agreed 20 max HP with the mods i have,,,puts me near 250 where i said i was.

you guys toss around numbers like crazy...

Brent, cool off. Telling mods to get out of your thread (figuratively) isn't a good idea.

I'm giving you facts. Your 03 auto sedan was rated at 260 crank hp.

Stock rwhp is around or under 220. Two things need to be considered. Most of the intakes make power up top, so you CAN add the 5-6 hp to the 220 to give you 226. The plenum mods on the other hand, make power in the mid range. Actually, the 5/16 spacer takes a loss up top, if I'm not mistaken. The larger spacers 1/2"+ (comparable to what you're running) gained a few ponies up top, but lost a decent chunk in the mid-range. So, let's say you get another 6 hp up top. Now you're at 230 rwhp. That's still 30 hp away from advertised crank numbers. Your exhaust and my grounding kit aren't going to gain you 30 hp. I'd be surprised if you were even able to make the 20 to get to 250.

When you look at it clearly, it's the integral (area under the curve) that is more important than peak power. Otherwise, you end up with something like my wife's 1zzfe with low torque, and high peak hp.

i hear you nate, and i know the guy is a mod..im a mod on another board, and i wouldnt come on a guys thread claiming his opinion is the joke of the day...its unprofessional.

im gonna go down on this swinging....im claiming near(just under) 250 to the wheel(peak HP)..and this bench dyno talk is pointless...when i go to the dyno, i will come here and rub it in all your faces.

so on that note:

[Sentientbydesign]

It's ok bro. You can rub your 250ish rwhp all you want, and I'll show you my 270+ rwhp and do this

Even though, when you calculate the weight difference, we'd be about even.

see you at the track punk!!!

[RED_DET]

15-20 hp is the difference between flywheel and to the wheel horsepowerso i hold my claim to be true. and it seems you agree by your statement above.hey if you dont want to discuss it ,,,,then dont discuss it anymore, this is a thread started by me, and i will discuss it all i want.

your the one who is fooling themselves claiming the jwt popcharger actually loses tq/hp by installing it.end of story.

I could care less who's thread this is or who started, so lets get that straight before we go any further.

Next you need to get a calculator and punch in the numbers 220whp + 21whp(which you didn't get out of those mods) but I will play along. I believe the final number comes to 241whp, last time I did my calculations. So NO, I don't agree with you because you are quite short of the "guesstimate" you have came up with. You are claiming you now have the advertised 260 BHP to the wheels. I'm telling you thats a "joke" and you are fooling yourself if you think so, especially if your car is automatic. The drive train loss on the G35 is around 18% for a m/t and even more for an automatic (20%). So the difference between bhp and whp is greater than 15-20hp. The 03-04 g35 sedan has also been proven to under-rated, dyno after dyno. The dyno's show that they are closer to 270-280 bhp depending on transmission. I have my own dyno to back up my claims.

Lastly, I never said the pop charger lost horsepower, I did say it lost torque and gained peak horsepower, which you agreed with in another thread I started. So before you go quoting me on something, please put the correct info. I didn't cry like a little kid when you said that I was silly for believing what I believe, so get over yourself when I tell you that your claims are a joke. It's my opinion just as you have one.

ok, enough said, i called you silly, you called my opinion a joke...lolbut moving forward:I still think there is no loss of Torque or HP with the popcharger install.None, not anywhere in the powerband.Thats is my claim. The powerband is shifted, but i believe there to be no loss at any point.are there dyno charts with a loss attributed to the popcharger?

[RED_DET]

I'm trying to find more information as far as dyno's go. The popcharger is very prone to heat soak, more than the stillen cai or the stock airbox. That alone will rob you of power.

I'm not trying to be a d!ck, I'm just stating facts and my opinion. I had the pop charger for awhile and loved it in cool weather and hated it when it got warm/hot outside. I just think there are better/cheaper options other than the pop charger.

When do you plan on dynoing your mods? I put down 233whp with just a pop charger about 2yrs ago.

I hear ya its cool outside here for now, but when it does get warm, i may opt for a true cold air intake with the filter down in front of the front tire..or, if your modded stock box with the z horn works out nicely, that could be an option..Actually if i had known about it before i may have tried that instead of the popcharger. I already had a drop in K&N in my stock box.

Id like to dyno as soon as i get 600 for the reflash. I dont think i will be doing much more modding to the engine until i can tune. Until then its shocks and sways.

[RED_DET]

No exhaust before the tune?

[toddnos]

No exhaust before the tune?

maybe, i like the way it sounds now.I removed the huge resonator box, and it seems to flow better, and rumbles nicely....i may do the y pipe, and then an axle back if i can find something very quiet.I would really like to improve the handles....it needs shocks before anything else im afraid. Then brakes, then sways....

[RED_DET]

I agree 100%. I have the suspension setup already. Now for the G37S brakes and maybe FI in a year or so. For now I'm going to see what the HR Y pipe is all about.
