hi

i was just wondering if a light weight car would make more horsepower or not?

just thinking if a light weight car would have more power but would it make more horsepower on a dyno

i have asked lots of people some say that it would because some dynos are specially for engines and it gives you engine horsepower and the normal dyno gives you horsepower at wheels

so what do you think

Mate I would have a go at re-writing that

But I know that when they strap a car down, how hard it is strapped will have an effect on the power reading but i think its fairly marginal and would eliminate most of the "weight issue' that your talking about anyway

Your not talking about power to weight ratio? I cant quite understand half of your post.....

Yeah I really think he must mean power to weight ratio or something. No one could seriously think that an engine makes more power just because you remove two fat chicks from the back seat.

Weight has nothing to do with power. You will have better acceleration because there is less weight to move - that's it.

There is a car club in the USA that got a standard Nissan sentra and started from standard weight and pulled a 16sec 1/4 mile pass. Then completely stripped the panels so it only had the engine, floor pan and running gear and pulled a 12sec pass.

weight goes not change the power of the car the power is what the motor is putting out !!.

but a lighter car will allow you to make more use out of that power for example if you have a 300hp patrol and a 300hp minni the minni will be faster because theres less weight for the 300 horses to pull

I think it is safe to say this does not need to be discussed any furthur. I think 99% of people understand that a car that is lighter will be faster than a heavier car with the exact same horsepower output.

yes, is this very much correct. A Lightweight Car Make More Horsepower because The "torque loss" sensation is a similar phenomenon, except it's mainly a problem with driving habits.

if i fit 22s on a 33 will it also make more horsepower?

Don't know about that one...

But it has being proven that if you paint your brake calibers red it will increase your power by 25rwkw & putting those flower stickers on the back window (like those you find in those Hyundai Excels, Getzs driven by girls) will furthur increase your power by 5rwkw per sticker.

a cars weight has nothing to do with "torque loss".

a car making "1000nm" will make it whether the car weighs in @ 1tonne or 2tonne.

drivetrain differences *might* have an impact, but it'll be minor for the sake of this topic.

And everyone knows there's 10rwkw in a TBI pod filter (the dyno graph on the back says so), and they're only like $15! So for $750 spent on TBI performance parts you can gain 500rwkw!

      RB25DET with solid lifters - which cams ?

      By TurboTapin · Posted

      Yea that's a fair assumption. I'm presuming they call them solid lifters as they have no moving parts like hydro lifters.

      Why am I hitting a power wall with my stroked RB25?

      I believe you're confusing WMI with water injection. Looking at that graph, the 93aki+WMI car is making more power than C16 race gas. Boost juice, which is what I also run, is Snow Performances 50/50 premix.

      GCG is a good company, they're a major distributor for Garrett in Japan as well.

      Nah, OEM washer bottle and brake fluid reservoirs are fine I don't know what it is with the plastic that Mazda used, some plastics, like the washer bottle and brake fluid res are fine, and still look new after 20 years use, where as the coolant expansion tank, and PS reservoir, that I replaced with new OEM items when I first got the car, turned yellow and started getting brittle a few years later If the dirty yellow stained plastics didn't trigger me there wouldn't be an issue, but they did, much like the battery bracket....... Meh As for going back to work full time to support car stuff, nope, why, because I own a Mazda NC MX5, not a Nissan R series Skyline 🤣

      I've never heard of CJ-motor, so can't advise you on them. I'd just go straight to GCG for a GCG highflow though. Seems no point to use a middleman. I'm somewhat surprised that the price on the CJ site is lower than the GCG retail price. Even though CJ would get a discount of some sort, you would hardly expect them to give up so much margin. Maybe the price is out of date? Having said that "I'd go to GCG"...when I did my highflow, I went to Hypergear. I did this https://hypergearturbos.com/product/rb25dethighflow/#tab-dyno-results with the R34 OP6 450HP profile. With the BB centre (extra $400) and intially with the standard boost actuator, but I eventually got him to send me the high pressure one when I got to the point of being able to actually use it. Ends up costing the same sort of money as the GCG highflow, but this is, of course, the turbo that I KNOW has a shorter length core and so moves the comp cover rearwards. The GCG apparently doesn't do that. My mechanic also swears by the GCG highflow, given that we have another turbo rebuilder who does something essentialy the same as theirs, using Garrett wheels. He says it stands up at really low revs and makes good power. I haven't pushed my HG highflow past ~240-250rwkW yet (should have a little more in it, but unclear how much) and it does have a fairly gentle boost ramp. OK, it's much better now that I have gotten my boost controller tuned up on it.  A lot of my earlier unhappiness was because I couldn't keep the wastegate flap as closed as it needed to be (including some mechanical issues). I'd still prefer it to boost up nearly as quickly as the stocker, and it certainly a bit slower than that. So maybe the GCG one is worth the first look (for you).
