my r33 dyno result

[Fly_With_Sky]

hi guys,

i just had an intercooler and electronic boost controller installed on my r33 this week and on friday she went on the dyno to get the mixtures right at the boost setting.

So far the one and only boost setting (atm) is 8psi and the car made 215HP at the wheels. However, i arrived a little later :Oops: ,and they did another power run and we got 210.4 HP. I was happy at this result as it is relatively low boost on an AUTO R33 (93 model) Gts25t.

I will be going back soon and we will boost it to around 10-11psi as that would be the max i would probably want to go with stock turbo and see if i can get around 230HP. Then take her to WSID :aroused:

The mods on her are:

- Greddy v-spl intercooler kit

- blitz dual sbc spec s

- k&n pod filter (need to box it up so it doesnt such hot air)

- custom 3.5 inch exhaust with 4inch dump pipe with a twin 3inch hi flow cat setup

the cosmetic add ons are side skirts and rear pods, GTR front bar, lowered kmac springs, 18inch rims and my boom boom system

my dyno graph had a little dip in it at around 150kph but was overall was a fairly good curve. What you guys think?

sorry, i should also add that me mechanic said that the drop was due to a stutter and suggested that i get the spitfire coilpack to fix the probelm for good. However i probably jsut do the easy thing and gap the sparkies to 0.8mm as its still at the standard gap.

Go to 0.8mm, you could run 1.2bar=16psi for short runs with the mods you have. I was doing that with my stock turbo [not ceramic]. Is the ecu still std???, 180km limiter etc?

twin 3" hi flow cat set up, i thought it would have been just as good to get a 3 or 3.5" turbo back exhaust with a single hi flo cat...

210hp = how many rwkw?

[crack]

210hp = how many rwkw?

156.6rwkw

yeh still a stock ecu

perhaps, but the guy that did the exhaust did the same system for a 32 GTR and the results were fantastic, so he did the same system to mine and i was very happy with the end product.

good work

get some aftermarket management in there and u will be able to straighten the curve

thanks, and some more boost too

[PTR33]

Yeah that dip will be at about 5000rpm where the stock computer dumps in extra fuel you would see it if you had AFR plotted on the printout.

It just gets bigger when you up the boost more. Mine is running 10psi. This run was in 3rd gear.

Speaking of boost, Don't try more than about 10-11psi on a stock ceramic RB25 turbo unless you want an excuse to hi-flo it.

[Fly_With_Sky]

yeh the afr's were like 10.7 10.8 10.9 around that, so were fairly rich. The max boost i would want to run on stock turbo is 10-11psi so wont be running anymore.

Hey mate i have the exact same car i have a blitz front mount ,sbc id 3, 3.5inch exst and a k&n fillter at first i had a apexi safc 2 as well which was pushing 169 rwkw at 11 psi (I still have the safc 2 if interested) then i upgraded that to a uni chip computer now it has 200rwkw at 9.5 psi i have been told i need some new coil packs and injectors before i up the boost cause it can't handle the power but for an auto it goes alright dont get a blow off valve it made mine run like crap idling up and down. i could of put the $500 from the blow of value towards some injectors !!

[Fly_With_Sky]

Yeh i am keeping the standard bov as i dont see any need to change it unless its leaking (which it isn't)

thats an impressive power output you have at that boost level, but i didnt think that there were ecu's from uni chip for the r33...guess i was wrong. How is the gearbox hadnling the power, are the gear changes any different from before the uni chip?

PM sent about the safc II.

[strutto]

Yeah I'd be interested in the answers to those questions too

[2BNVS]

rb25 gear boxes are extremeley strong they can handle massive power...

ben...

[Fly_With_Sky]

2BNVS, we were refferring to the AUTO gearboxes for the r33 not the manual g'box.

[nmcmahon83]

I reckon that dip at around 5000 is probably more likely dodgy coil packs... mine has the same problem... Does it pop at around 5000RPM? If so, there are numerous threads on how to fix that problem (just havent got around to doing it personally)...

Good luck.

[Fly_With_Sky]

yes it stutters sometimes and my mechanic pointed out to me that to eradicate the problem fully he showed my the splitfire coilpack, but to start with il just regap the plugs.

All stock GTS skyline turbos are ceramic(turbine). From the R32 to the R34. The series 2 33's have a composite compressor aswell as a ceramic turbine and give the best response by far but are prone to breaking blades.

[MR R33 GTST]

There is a uni chip for the auto skyline but not all models can have it i got mine done by dyno motive in melbourne it was very good if i can find the dyno run i will post it up on here there is no difference in the gear changing or anything they done a top job all only thing i realy notice is that i need a shift kit now cause if i manualuly change the gears it aint quick enuff but yeah i am very happy with it. if you wanna know prices and stuff pm and i can tell u
