our CA made 260KWs

Post by **cortina-mk1** » Mon Jul 12, 2004 11:50 pm

just had our new engine on the dyno

we made 260 KWs (348HP) @ the rear wheels @28 psi

we made 200KWs (268HP) @ 18 psi

pretty pleased

Very impressive! Congratulations!

Those are some very nice results! What turbo are you running?And where can I get some more pics like the first one on this page- http://www.cortina-mk1.com/engine.shtm ???

pics? as in cutaways ? or ..?

have now uploaded dyno sheet

you can find it herehttp://www.cortina-mk1.com/engine.shtm

348 whp on 28 psi??!! Is that tuned well? or just a baseline run? What turbo?

Post by **nab911** » Mon Jul 12, 2004 11:50 pm

Maybe those are lower compression pistons... and if they arnt then i didnt know the motor could hold 28 on stock rings.

I hope its base run.

Post by **quest** » Mon Jul 12, 2004 11:50 pm

seems like an awful lotta boost for 348 whp. Are you trying to push that thru a small frame T2x turbo ?Aren't the more common dynos u aussie guys run, more like the mustang dynos in the u.s, rather than the typical dynojet that tends to read 15-20% higher ? Quite a diference if thats the case.In any event, you're making solid power and I'm sure that car is fast.

Post by **Nismo1182** » Mon Jul 12, 2004 11:50 pm

Exactly. Built internals, tons of boost and only 348 whp. Im not saying the motor or set up is crap but something is definately wrong. Which is why I asked if it was just a baseline run.

Post by **cortina-mk1** » Mon Jul 12, 2004 11:50 pm

who said anything about running stock rings....certainly not stock rings

i think you may be used to higher readings on your dynos over there... and also it says above new garrett roller internal wastgate turbo certainly not a t25

it strikes me a amusing

why would you think there was something wrong ? nismo 1182?

Post by **cortina-mk1** » Mon Jul 12, 2004 11:50 pm

could any of you tell me what the results of rolling road dyno runs are in the USA? or your own perhaps?

to see what the major differences are maybe and the times they have recorded on the 1/4 mile if available.

Post by **nab911** » Mon Jul 12, 2004 11:50 pm

Yeah im really intersted in finding out if the dyno's we are running are crap here. Also, what fuel did you guys run and what size IC piping do you have?

Post by **quest** » Mon Jul 12, 2004 11:50 pm

Reason for the comments probably because that amount of boost not common with nissan 4s. Whenever you do see 26-29psi, its most likely on an sr or ka with at least 500whp.Typical numbers? sr and ca pretty close;t28, fmic, 3" exhaust, oe ecu usually gets ~280whp @17psi. Same as u posted. 2700 lb street cars run low 13s... consistent with uk guys. If u wanna master your launch/drive technique, run slicks, etc... u run well into 12s.A junkyard 60trim T3 can hit 300whp @18psi on a ca18. Rather than run the boost way up with hard spinning small huffers, run a bigger one.

There is tons of on the net that basically form the way we choose turbos. Take a 3300 pound dsm 2.0L for example.16g turbo, 25psi, race gas, fmic, 3" exh, runs 12.3 well tuned.Switch *only* to a t3/4 50trim, run same et at 17psi on pump gas.Efficiency... works for sr, ca, 4g63... doesn't matter. Turbo stays in its "sweet spot", lasts alot longer, EGTs and inlet temps lower, etcOver this side of the pond, 26-30psi cars are most likely 10sec 3000 pound fire-breathing, 4 cylinder monsters

Post by **Nismo1182** » Mon Jul 12, 2004 11:50 pm

Exactly.

Might be the dyno and what im used to seeing. But when I see 28 psi and only 348 whp I think something is wrong. Im used to seeing 2.0 liter cars putting over 400 whp on 28 psi. Enjukus own car does well over 500 at that boost level.

Post by **fanta** » Mon Jul 12, 2004 11:50 pm

PSI is just a number.

Nice numbers

Post by **Nismo1182** » Mon Jul 12, 2004 11:50 pm

yea its just a number but its a high number. whats the efficiency on that turbo at that psi?

Post by **boost_boy** » Mon Jul 12, 2004 11:50 pm

First of all,

I love the detailed pics and info of your website. I felt it was tastefully done and I totally understood your evolution with your cortina. But back to the topic at hand, I too am curious as to why with all the bling-bling goodies in the motor (which by the way is beautiful;) ) were you only to extract 328whp out of 28psi? That's a lot of boost for so little of an output. I'm with quest on this in that most nissan 4s that are built to party, pumps out around mid to high 400s to the low 500s whp.

Quote »could any of you tell me what the results of rolling road dyno runs are in the USA? or your own perhaps?[/quote] All my dyno runs were done on Dynojet models and they were very near your HP levels with no where near the amount of mods you have. Factory stock bottom end with the addition of T3/T04B stage I (.63 rear and .60 front), HKS camshafts, MSD 50 lb/hr injectors, and an SDS standalone tuned by me in my novice days and I was able to muster-up 299whp on 16psi and then on the final run 312.5whp on 18psi of boost. At 15-16psi on a CA18DET 50 lb/hr injectors are very close to 100% duty cycle with my own injectors seeing 109% duty cycle on 17-18psi and a bigger T3/T04E stage III turbocharger.

And I know for a definite fact that this same car that belongs to my g/f is very well capable of running low 11s, but it does not have the suspension to support such a quest, though I try and improvise. I would probably try another dyno if I were you because realistically, 348whp is pretty low for that amount of boost on a CA18DET. Please don't take this the wrong way friend, but people are giving your accomplishments praise without realizing that with the amount build-up you've done, you should be pumping out bigger #s than that. Congrats on not blowing-up anything though! Says a lot about the way the engine was built.

Very sexy engine you got here humm make me drool

Post by **cortina-mk1** » Mon Jul 12, 2004 11:50 pm

thanx all for the info and comparisons much appreciated

all i can say is that a very very good CA18 here i australia has never gone past 310 rear wheels kws. and that particular one was a stroked tomei version

ca18 powered cars here running mid to high 10 second quarter mile are only in the 230 to 260 rear wheel KW range.

the engine is running fine and i certainly wont be changing dyno tuners

we are very happy with results.

the other thing to notice is the rpm on that graph. we have not yet used any of the rpm capabilities of this engine yet.

also in case some of you dont already know our old engine only made 180 rear wheels KWs and it was able to run a 11.9 @115 MPH quarter.

the weight of the car without driver would be around 1200 Kg. it has a full interior and is not lightened in any way or is it going to be.

we have been to the dyno many times with our own cars even engine dyno with one of our engines. so we are no stranger to them.

we will run on goodrich drag radials as well as our slicks but primarily will be on street tyres.

60mm IC piping

i also dont like comparing apples with oranges. every dyno is different from one tuner with same model/type of dyno gave a 20 KW higher reading on exactly the same day same car within a couple of hours..

if the weather stays ok i will be running it this weekend .

Post by **cortina-mk1** » Mon Jul 12, 2004 11:50 pm

i just realized you may not be familar with metric KWs etcso here is the converted

180 KWs = 241 HP20 KWs = 26 HP230 KWs = 308 HP310 KWs = 402 HP

1200 KGs = 2645 pound

Congrats.. looking forward to hearing some track numbers, these are the ones that really count at the end of the day. Im sure you wont dissapoint

fwiw.. RPM performace centre (AU) has a 180sx non stroked with a 311kw/wheel @ 1.93bar... 11.9 @ 117mph

yes niscort i know of the South Australian car in fact i have posted in another thread the actual engine picturehere it is if others have not seen ithttp://www.rpmperformancecentr....html

yea well was looking good for tonight but seems to be a lot of clouds just come in

arr well always sunday @ heathcote
