250rwkw is dangerous on the R33 320/370cc items.

I've known rb20 injectors to be pushed to 243rwkw on 17psi of boost.

The car went on to run 12.8, I can't remember the TS. :(

It was Clint32's old 'street' R32 before he attacked it. :D

I don't want to start a dyno argument here, but...............

12.8 for 1/4 = 311 horsepower using the heaviest weight I have ever seen an R32GST plus 120 kgs for the driver. That's around 180 rwkw, which is what I would expect out of a set of standard RB20DET injectors wiht a bit of extra fuel pressure.

Therein lies the problem, I see all sorts of miraculous horsepower claims from standard injectors. But when we run the car on another dyno or down the 1/4 they amazingly come back to what the calculator says they should make.

:D

I'm all too aware of different dyno figures.

Especially the difference between corrected (shootout) and non shootout mode read outs.

Next tune I will have this done on Boostworx dyno. Lets see if the shootout mode reads higher. :D

I suspect it will.

Exactly why I stated the power figures. :(

The car also wasn't kicking you in the arse until 5000rpm.

So you think my 176rwkw with basically 100% duty cycle is around the mark? :D

I can't see my bosch pump having issues supplying fuel at that power, especially considering its only using 9psi to make that power.

But.. you never know.

Sydneykid - fyi there is no way in hell an R32 with 180rwkw is going to do a 12.8. Not even close. Maybe a low 13, but not in the 12's. My S15 with 195rwkw ran 12.74 @110mph with a very good 1.94 60'.

"the obvios answer tho is if you want to make over 200rwkw its alot safer to upgrade your injectors etc"

If thats the obvious answer then the answer to your thread is obvious.

As I mentioned I made 187rwkw and I got a call from the tuner ( I said I would be happy with 200rwkw) telling me I could have my 200rwkw if I wanted an a/f ratio in the 13s but he wasnt going to take it there.

After a long drawn out slog which I wont get into in this thread I got my car back today with 235rwkw (rb20) using 510cc injectors,standard reg and a GTR pump.

I have seen up to 80 psi on the fuel gauge under full load/boost, and have not had any problems with fuel leaks in nearly 3 years and 50,000km while my car has ran high pressure.

I dont see the point in him upgrading his injectors if he can acheive the power he wants with the stock ones, he has said in post `1' he would rather not upgrade due to lack of $$$.

It's not "my" 180 rwkw, I just used the trusty (well sort of) Moroso Horsepower calculator. It says 311 bhp, and based on my trusty (very) calcs that's 180 rwkw. Blaim Mr Morsoso not me. :P

BTW, our R34GTT ran an 11.9 (at 120 mph) with 265 rwkw, which is within 20 bhp of the horsepower Mr Moroso reckons it would need to do those numbers.

I think it comes back down to the old 'Average' power

Yes, I reckon it does :uh-huh: :uh-huh:

I run 114mph with 215rwkws, and there are cars at the drags running 11s with 108mph:(

If you need to get a major clean up of the tune id say grab the injectors (may mean saving up). If the bloke tuning it says std injectors are ok, and he will stand by his tune then i would begin to consider...the guy tuning should have the final say as you dont want to turn around and cook a motor and have him say "i said you needed injectors":(

    • Crazy how good the aero bar looks compared to the stock one
    • Yes, but you will need to rewire all the things that are different. CAS, coils, etc. Yes, but there is no IAT. What? You can use anything you like. It just has to be hooked up so that it will work.     Or are you wanting to just plug and play without having to do any thinking/work?
    • It's been a little over a decade since I bought the S15. As I did on my socials, I'll share some of my favorite pictures from over the years further below. If you haven't realised, pretty much all the pictures in my posts are ones I've taken.  In terms of updates, I don't have pictures, but I acquired a near-perfect pair of fog lights from a friend of mine, so those got swapped in for the pair I already had. As for the JZX110, I just got it back from being fixed. A few weeks back, I was on the highway when I suddenly drove over something with very little time to react. It was probably the size of a soccer ball, but it went under the car and banged into the underside pretty loudly. I pulled over and realized the fluid leaking was fuel, and of course, it was right near my exhaust. This required replacing the fuel tank. If you happen to be in the same predicament, thankfully this car shares a fuel tank with the JZS171, IS200, and IS300, so it wasn't too painful to replace. Enjoy some pictures as mentioned above, including the carnage from the fuel tank and a bonus picture I came across which shows how ridiculously shiny the Bugels are on the 110. So many more pictures I could share of the S15 but this will do for today, enjoy. 
    • Welcome.  Was the mistake the car, or joining us? 😏
    • Yeap, was me and the daughter getting coffee before heading to the new joint to measure up the fridge space and taking some pics that the solar installer wanted of the switch board
