Rb25det 230kws Vs Sr20 190kws

[geraus]

Hey guys how are ya's. I recently went in my mates s13, The Geforce felt really strong to mine. Why is this? Like the power was unbelivable.. compared to my 230kws RB25DET in my R33.... is this because its a heavier car? and lighter car?

Just wanted to know your opinois boys...

Has a lot to do with how the power is delivered. The SR20 provides more of a turbocharged 'hit', whereas the RB25 is a lot smoother and more progressive in it's power delivery.

Weight has a bit to do with it also, as does whichever dyno each car was run on so don't take the figures as gospel unless they were both run on the same dyno, on the same day one after the other.

There could be many reasons why the "Geforce felt really strong". When you’re the passenger everything feels different or were you driving the S13?

Big pot 4 cyc, light weight, always going to 'feel' snappier.

Also depends on what turbo each car has and so on.

a ball bearing turbo usually feels more progressive, where a bush it 'all in at once' from my various turbos over the years

as said about are you the driver or the passenger in the S13? as when ever a mate drive my car it feels 10 times quicker than when i drive it and visa vera with there cars.. just a wierd thing that happens i think

+1 for passenger seat feeling faster

Well you know how fast your car is, and you know when you are expecting to give it a hit, your mate might just give it a quick boost before you relise!

anyhoo,

after driving my old r33 with 254rwkw (gtrs turbo)- with truck loads of torque, it felt quick, but as Ash said, not "snappy!"

I then drove s13deviats 210rwkw s13 with s15 turbo, and it came on boost hard and quick. the s13 felt quicker mainly cause of this snappyness, however top end the r33 would just keep pulling hard with no issues of struggle.

now I have around 70rwkw so everything else I drive seems like a rocket haha

+1 for passenger seat feeling faster.

never ever been in my passenger seat in my car.

i trusted someone enough to let them have a go with 350kw.....and i always call my mates pussies when they scream.

i can honestly say i havnt been that scared in a while lol.

Thats it! Im going to swap my front seats over then if the passenger seat is faster

If you’re driving and you put your foot down, you subconsciously brace yourself. Where as if your the passenger it just hits you all at once not being expected. Driver and passenger are two different experiences. Of course how the boost kicks in makes a huge difference as well.

Too true. Quite a few times I've let mates drive my car which I'd say is slow but when I'm the passenger it's a different story. I've also been the mates cars and thought they were complete animals until driving them myself.

+1 to all of the above. Other thing to note is that the r33 would be putting down a higher % of its power down to the ground then the s15, thus making it feel more linear and progressive.

Both cars are an absolute jewel tho!

[kralster]

The passenger seat always feels faster.

i drove a s13 putting out less power than my 33 at the time and it felt a fair bit faster, however as far as times over the 1/4 went they were pretty much the same. as people said, it's all about delivery. the sr20 kicks in much harder and faster, where as the rb25 is a bit more like a NA where the power is there from very low so you don't go from having a bit of acceleration to a lot of acceleration in a hit.

back when i had my 180sx (turbo sr20), the missus SSS pulsar (natro sr20) felt (and was) a fair bit faster coming out of most slow corners in second gear. since the stock s13 turbo doesn't really get up and going until close to 4000rpm, the pulsar would just pull away until the 180 came on boost and started to catch up. pulling out of our street and flooring it up the hill, the pulsar pulled much harder below 4000rpm but as the revs got higher you would be waiting for the kick, where as the 180 felt sluggish down low but then felt much quicker up top once the boost kicked in.

Yeah Passenger seat is where it's at.

I let my mate drive my car once from my place to his joint. I backed it out of the garage and put it on the street, and turned the boost down to channel 2 on the EBC which was only 12psi. We drove sedately until the temps got up and then he asked if he could hit it. We were just coming out of a roundabout onto a wide open stretch of road (1 lane each way, but had big parking lanes on each side) and when he stomped it in 2nd I nearly lost my shit. It sorta almost took my breath away, I made him pull over straight away so I could check the boost controller and couldn't f**king believe it when it actually read 12.2psi.

Major difference in the perception of speed and accleration from driver to passenger and I can now understand why people get out of my car shaking.
