What sorta power should i be getting @ the wheels out of my RB20DET ECCS with the following mods :

* 3 inch dump pipe into a 3 inch hi-flow cat, 3.5 inch zorst from the cat back

* 10 psi of boost

* k & n pod type air filter

I got it dynoed and wasnt too impressed with the outcome, not that i was expecting big horsepower but this wasnt much of an improvement from the standard power output. I got 160hp @ the wheels.

You guys reckon this is a pretty accurate reading or is the something wrong with the car?

cheers

sLo :P

power? you should use 240V AC if your in Australia.

Seriously, don't worry about comparing dyno figures except with your own from the same day and dyno.

Is 160rwhp too low? Probably not. Why don't you see how fast you car is. If it's too slow for you modify it some more.

If beating other people in a dyno comparison is what you like to do then knock yourself out.

I had exactly the same mods and made 109kw at the wheels with 10psi.

I will not put my car on the dyno again unless I have added a substantial mod and want to see what I have gained or am getting something tuned at the time.

Trying to keep a handle on maintanence negates me modding extensively at present.

I feel slow sometimes and when that happens I go drive my g/f's mirage or someother sh*tbox and then get back in my car again. Trust me you will feel the difference!

edit-sorry, tell a lie I only had a catback on the dyno.

slo-32 - I got 114rwkw when i had mine done last Thursday. Had the same problem as you with timing i saw in an earlier post of yours, except my timing had been set wrong. Started at 70kw and i thought what the! after that they realised the timing had been set wrong and ended up getting 114 :( very happy with it.

Mods i have are pod and turbo back exhaust and running 14psi i think on the Apexi AVC-R i had installed on the same day. Nor unless they did the power run at 12psi, but dont think so. Cant wait to see what it'll do with a few more mods i wanna do like cooler and bigger turbo :D

BTW - what is conversion of hp to rwkw?

Mine was 143rwkw with Trust element in the stock airbox, HKS Super Drager cat back exhaust and Supra front mount cooler, stock boost.

With a pod filter, front pipe, custom FMIC it made 153rwkw at stock boost

Chris

itsallgood : 160rwhp = 119rwkw i think...well around that

... 153 rwkw?! You sure you dont mean hp? Surely a FMIC doesnt give you that much power does it? Correct me if i'm wrong.

yes u r very wrong, fmic gives u about 30rwkw gain at same boost level over stock cooler.

Stock cooler is the biggest restriction in the whole system.

I remember alot of ppl saying a fmic doesn't really do shit with a 32? Either way i should have mine back (fkn taxi ran me off the road) in around another month. She comes back with a micks metalcraft 600x300x76 so ill be able to comment :P

With stockbox, 3" exhaust str8 thru, 10 psi, and timing on around 30 (no pingage pphhoaarrwww) we were on around 138rwkw.

What have other ppl noticed that have swapped to a fmic in a 32?

I've run 35degrees base timing on regular bp98. About 25-30degress at the moment.

fmic will always make a difference. The peak power will be higher for sure. The only problem is some 'oversized' fmic packages will lose response over the factory and make the car slower to accellerate over 400m.

people who say fmic dont make a difference obiliously dont have one or have even had one!

I agree with you totally, though from everything ive read, suggests that without say a new turbo etc, changing the IC on a 32 doesn't make a great deal of difference.

Now ive seen 100 of ure posts saying "omg my fmic gave me 30wrkw" :D, im just wondering what i should be expecting...5? 10? 30?

Yes INASNT...I have never had a FMIC. In fact this is my first turbo car and still learning alot about them. And I am learning a great deal from you guys at this forum.

The only reason i questioned the power gain from a FMIC is becuase i've been in a s14 with a cooler and one without and the one without went alot harder / better. And they pretty much had the same mods. But i now know there is many factors that could have made this be.

Thanks again

sLo :D

I never dyno'd it with the stock cooler, but I reckon it was around 120rwkw. As I said before, with the 7MGTE Supra cooler it made 143rwkw, and with a proper custom job it made 153rwkw. All with no change to the stock boost.

Currently its making 198rwkw with a HKSGT2510 and a re-mapped computer and decent intercooler.

I'd recommend a bigger intercooler to any one with a stock cooler, the amount of extra grunt thats lost through the stock cooler is a joke, and retaining it is also a joke - bigger is better!

    • Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!
    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
