S1 R33 gtst 3" full x force exhaust with high flow cat GFB bleed valve set at 11 psi SAFC2 highflow ball bearing turbo apexi FPR FMIC walbro 550 hp fuel pump stock injectors stock internals 307rwhp

didn't get torque figures but here is my dyno sheet

very nice, they look so much nicer with tint

307 rwhp at 11 psi, very happy

give you a close up of the driver, a close up of the plate and a pic of the whole car. got done for 11 over in my jackaroo last year

when did you check your plugs last?

ok, 2 1/4 with no bleed gave me 10 psi. re fitted bleed valve(set at 12 psi) and went to 12.5 @ 7000 in 2nd. my problem looks like too much flow through exhaust. booking in to get full tune next week and hopefully around the 300 rwhp figure?

ok, just fitted a 2" restriction plate between front pipe and cat. took the car for a blast and sat rock solid on 7 psi (have taken bleed valve out and gone from standard tapping point to waste gate). waiting for car to cool down and will fit a 2 1/4" and see what that does. will keep updated!

very nice mitchy. just keep an eye on the rear veiw mirror. how will it go going over the pits?

no, just a bleed valve. whats the price of the ebc you got?

i,ve been reading this thread very closely, and have just about done everything here. bought a high flowed turbo(same as the pics last page) had no problems with boost on my stock turbo, set at 12 and dropped to 10 as all bleed valves do. thought id chuck on the high flow and set it to 12 to 13 psi as i still had stock injectors. went for a tune and went to 12, leveled and slowly climbed to 17 at the end of the rev range. since then i have remover the turbo and machine out the waste gate hole from 24 to 28 mm giving me a 36% increase in surface area, didn't work. had a 2 1/2 " split pulse dump pipe that i modded to a bell mouth, didn't work. got rid of the dump pipe and put a 3" bell mouth front/dump pipe on, didn't work. swapped actuators, didn't work. removed the bleed valve completely and put it directly onto the standard tapping point, didnt work. i am now about to go the other way and put a 2" restriction plate in my exhaust to see if that rectifies the problem. the car has been detuned to 230hp at the moment so i dont pop anything. i am running a safc2, full 3" exhaust (only restriction is the cat).

so does not enough restriction = loss of control of boost from 12 up to 17 by 6500rpm (highflow turbo)

might want to put this in the want to buy section in the WA area mate.

theres no dyno figures in the members section, only 1/4 mile times Bubba

had a quick look in the book and the only numbers i can see amongst all the jibber is 0000. unless the workshop that tuned it locked it with another number

anyone know how much more power you can get out of a stock turbo with VQ30DET rear housing. i got 290rwhp with stock. have got a high flow on at moment but having problems with controlling boost

cant sense boost but can sense airflow, if you get to much air flow the computer will change timing and theres your boost cut (as such). are you running any after market computer or piggy back. this will help if not

sorry its created motorsports, think they quoted me like 700 bux to get done

i asked about doing this to my tuner, he slapped me and told me to get real ones, still saving. i think dirtgarage does them in sydney

difference between running a rb25 at 12-14 and a rb20 at 12-14. think you are unlucky. i've been running mine at 12 for the last 4 years with no problems and it was fine when i pulled it out

go get a second hand one, plenty around, (i've got a s1 for sale). be around 300 to 350 for a good one, not to hard to change. give yourself a day and that will be plenty

stock is 5 and 7 psi. go get yourself at minimum a SAFC2 fuel controller and get it tuned with that

they will let you mod your car, but if it causes the accident, eg too dark a tint and you pull out in front of a car, you will not get paid out. with just car too 3 cars, house and contents. very good

watch those kerbs
