ACURA~

Hey guys just thought i would get a conversation going on about acuras. Pretty sure the acura integra acura type r dominates alot of shit. but the acura rsx dominates almost everything. its got a 2 lt. vtec k20A3 motor with a 5 speed tranny. Thats the specs for the base model. Anyways It one of the best street cars for cornors i can throw my rsx into a cornor at 60 and dont skid or slide in my seat a inch. anyways. What are your guys thoughts on Acuras

I like em as long as you don't put a upside down Honda badge on it.

Is yours a base a typse s? I haven't seen a type S with a 5spd unless its completely aftermarket. One of my friends has a 94 EG Hatchback witha K20/K24 engine and 5spd tranny in it, its N/A and he runs mid 12's with it but his trap speed is low compared to most cars in that category. I used to own a 2006 RSX Type S. I miss my little DC5 but I like my Z a lot more but heres a few picks. I had Toda Race Header, Vibrant Cat Back, AEM CAI, Innovative engine mounts machined in red, and ITR stage 2 cams. It made 227fwhp over 162 stock.

I thought the 06 Type S was 210hp stock???

The baseline and results at the wheels. Its 205hp stock and on a DynoDynamics it produced only 162hp at the wheels which sounds about right for how FWD cars lose power to drive train compared to AWD and RWD. So it was putting an estimated 267-277 at the crank. The sad part is because I had 4.10's in it, it pulled as hard my Z did stock to 60 from 5mph!! The after 60 my Z took off by about a car in each gear. If I would have gotten rid of the Type S seats and it had no sun roof, it would have the same lb/hp ratio as a stock 370z touring which is pretty good compared to most cars you see. I pissed off A LOT of mustangs while I had that car haha now I don't even waste my time with them unless its a Roushe/GT500 or terminator.

This is interesting. A Fwd car loses MORE to the driveline than a RWD or AWD? Logically to me that makes little sense. I always thought the extra length and rotating mass of the propeller shaft going to the rear wheels, plus the loss to the front wheels in an AWD would be way more than a FWD... assuming both were manual transmissions. Hmmm...

If your stock crank hp is 205, and you pulled 162 to the wheels, that's over 20% drivetrain loss and seems quite high compared to most other dyno results I've seen with FWD cars... now my head's hurting.

To answer your first question, FWD lose less hp than RWD adn AWD. From what I have seen from multiple dynos, it goes in order FWD<RWD<AWD. And AWD takes a hard hit! Look at the mazdaspeed3 vs the mazdaspeed6. The mazdaspeed6 gets to 60 faster but the speed3 catches up by the end of the 1/4 and will continue to pull ahead due to a better power to weight ratio and drivetrain loss.

The dyno dynamics I went to for my DC5 was a notorious "ball breaker" dyno by it produced the most consistent numbers from the forum members feed back. The main thing a dyno should be used for is to show progression through mods or tuning. If you try and compare a dyno jet to a mustang dyno the numbers will vary extremely and the same goes when trying to compared the exact same dynos. All dynos are calibrated differently and give different loads on the vehicle. Also some places don't open the hood of the car, some use 3 fans while others use 1, some even take off the front fascia of the car! All these can and will produce varied results if not consistent, and ambient temperature is a big factor as well. When I took my 370z in to the dyno shop out here in San Diego the guy didn't turn on the fan at first and I made sure he did. I even went as far as writing the make/model and last 4 digits of the fan to make sure the next time I go he uses the same fan. Even if my Z dynod at 250hp I would be a little bummed yes but after all the mods I add to it and it dynos at 285 I'd be happy. Even though most other Z's are putting an average 280 to the wheels, I added 45hp to it from the mods. Basically meaning from the stock 332hp at the crank, its now making roughly 377-387hp at the crank and some people would say itd be even more than that due to much more than expected drivetrain loss. My Z didn't dyno at 250 but made average gains if you compare the dynos but like I said, you can't really compare differewnt dynos even if they are the same type. DynoDynamics tends to read low for most people but the place I went to had both a Dynojet and Dynamics and both produced nearly the same results which supprised me but all I needed it for was a baseline which is important. Some dynoshops have been caught adjusting their calibration loads on their machines just to say their part you bought for $3,000 worked and made 65hp over stock! The owner doesn't know any better and thinks his car is much faster after he just bought the $3k exhaust bearing!

Hah ok so I'm not going crazy. Yeah I always figured it was FWD/RWD/AWD when it came to drive train loss. Its no wonder most of the R/C speed records used to be made with RWD squirrely sedans with fat foam tires as opposed to AWD which is a bit more common now. But that's another tangent.

Yeah I understand what you mean about at least having a baseline reading with something to compare against with mods etc, and needing consistency over absolute accuracy in that sense.

I was just surprised when you said something about you losing all that HP to the wheels on your Acura and that made me think you were saying FWD loses more than the other drive trains.

I think my 20 hp muffler bearings aren't working. Good thing I only paid $175. They're supposed to spin smoother than the poly bushings I was told, which lets smoke go out faster = faster car.
