Just an update guys, after a couple of weeks of diagnostics to eliminate any other possible issues and another mapping session by Mark Shead. The car was dynoed again yesterday and only made 512bhp at 2bar. This was exactly the same reading at 1.3bar and it seemed to be loosing performance as the boost was raised. The turbo was working at full capacity so obviously the turbo was only rayted for this type of power. Everything has been eliminated and we are now certain that the manufacturer of the turbo sent the wrong turbo when it was ordered. I am been speaking to the provider for the last couple of weeks and he has been awaiting our results. I am hoping this issue will now be resolved asap so I can enjoy the car before the little summer we have left goes.

£30 mate and I will take it

Not the scariest as it wasnt planned but definitely the unluckiest at the time Blown up in N.Ireland in 1992 whilst on patrol Funny thing I swapped sides of the road with a mate just prior to the alleyway, i walked past the alley way and took the blast, the mate was safe on the other side of the road in my original spot.

Hi Alex Hopefully have some answers today or tomorrow on exactly what is going on. The turbo does not seem to be making the power stated, hopefully as suggested, a shipping mistake that is easily and simply rectified.
-
Simon My housing is 0.70 so larger than yours and I am making alot less power. This is puzzeling, maybe the compressor wheel on the inducer side is not T67. I am hoping to have some answeres today either way, the car is going on a dyno at 2bar to see what the top end power is, if it does not make or get near to the quoted bhp from the manufacturer especially as all others areas have been exhausted, the problem has got to be the turbo.
-
Nic The turbo seems fine with regards to damage but once confirmed that the turbo is not making the power they quoted, we will be contacting the supplier reference specs to ascertain whether they sent the wrong turbo.

Hi Ian The info you have mentioned regarding possible causes, I will try and get this from the mapper and builder. The people involved in the build and mapping are very competent and well regarded. I am sure all the possible faults you mentioned have been checked and are correct. Out of interest you run a T67 what is the exhaust housing size as you are making 600bhp. Nic, the 520 is at the flywheel, I would be happy if it was at the wheels:)

Hi Alex The car is operating 272 cams intake and exhaust, veilside intake, hi stall torque converter. In terms of the build I would of expected 600bhp at 1.4bar based on other members cars achieving that on a similar or lesser spec. Presently my car is making 520bhp at 1.4bar and will not increase above this at 1.8bar. All supporting electronics such as EBC have been checked with no problems. Everything is pointing to the turbo. Presently i do not want to name the turbo but it is from a reputable dealer and do not want to start bad mouthing anyone until they share the exact spec of the turbo with me so I know who is at fault.

Hi Alex I hav'ent drove it yet on boost, the mapper and builder have and they said its fast but definitely not right. The engine has been built to take 2bar, the turbo is making no more power at 1.8bar than it is at 1.4bar, the sage continues Hi Jamie I trust the builder and mapper and I would hope the supplier would not/has not made an error.

hI folks, i am hoping someone can help me with this, I know there maybe small differences but on a T67 what would be the standard exhaust housing A/R size based on a turbo rated to 650+ bhp. My T67 is not making anywhere near the power it should and all aspects of the car have been looked over so there are no boost leaks, faulty wastegates etc. Supporting mods suggest I should be looking at 600+bhp at 1.4 bar but am way off this. A uk specialist has had a look at the turbo and has said the A/R is way to small causing the turbo to choke. The guys with T67 making 600+bhp, what size is your A/R on the exhaust housing?

I thought with the AA, the member has the cover, does'nt matter what car, if your a passenger etc. I have the top cover, I had a flat battery on my drive, they came out and recharged the Supe, no probs

Hi everyone I am hoping will have the answer to this question. I have a Greddy Profec E01 Boost controller, does anyone one know what the boost solenoid is rated to. Is it a dual solenoid capable of 2bar+? I am searched on here + greddy site but cannot find the answer anywhere. Thanks Mark

Ah the originator of the thread, I suppose I owe you a big thank you for providing th eproduct to Gaz1 so he could then sell them to me. For that your car gets my vote for "Best Supra on the Forum";) - seriously though your car is definitely up their with a few others
-
Cheers Gaz The seats and the wheels were the buys of the century, your seats look great mate and have finished the car off. How is your car going mate, I have been reading some of your recent posts, car looks great and has very impressive figures. I am hoping mine will be similar! Hopefully I will be able to drive the car this week as final mapping to be completed asap. Missus is grieving me, she wants rid of the car - NIGHTMARE

link changed, cheers

How about this one mate, I would be looking for more than £15k though but the engine has just finished being run in, final mapping this week, should be 600bhp+ Not sure what the price would be, missus is hasseling me to sell:rolleyes: http://www.mkivsupra.net/vbb/vbpicgallery.php?do=view&g=1991

Interior changed now (thanks Gaz1) so looking abit better from the inside, I also have some new wheels. There are some wicked supras on here so God knows which is best, however I am in agreement, overall manuals score higher than autos which is a bugger as mine is an auto.

Topman, got my new card - member now until 25/08/27 - I wander if the Supra will last that long:)

Thanks mate, 35 now, not sure where the years have gone but things could be worse.
