I have finally got my Hypergear TR44 High Flowed installed. I have had problems with a leak from the back of the intake housing. The turbo took a trip back to Melbourne (under warranty) and now all is good 
Next on the list is to do the cam belt, tensioner, Adjustable cam gears, water pump & serpentine belt. As she is up for her second 100,00km service. Hopefully all the gear should arrive in two weeks from a group buy. Then its time to tune

you'll find that you need heat shield for the rear housing.
Nice engine bay. |

Yeah took it for a belt yesterday afternoon. It was 34 degrees in Bris. Popped the bonnet when I got home and the area behind the rear housing was very very hot. One of the rubber hoses was smoking a little. |

Shouldn't use those hose clamps. They may look nice, but they are so inferior compared to the cheaper looking hose clamps. Basically those clamps can leak under high boost.
I agree with danny, get a heat sheild/turbo blanket asap.
Other than that looks good, now get down the track after it's tuned  |

Any proof of that, T-bolts provide more even pressure and you can tighten them further. Not trying to rag on you just curious if something happened to you with Tbolts? |

A workshop who builds turbo and supercharger kits for a living. They are just not flexible enough. |

Hmmm ok well May have to look at some new clamps. Just the standard screwup type the best? |

i have had no heat shield for 1.5 years now..
i dont have any heat issues in my engine bay. mind you im not running very aggressive timing map and i dont think my exhaust housing gets that hot.
my car is consistent run after run.
also looking at those pics, the t-bolts are only on the intake of the turbo.. who cares if there is a leak there? also cant see why they would leak when so many high power cars / drag teams use them.
nice work grant.. this car has come along way since i first saw you at willowbank almost 2 years ago. |

They are on the other side mate. Umm no high power cars/drag teams use them. They use something that looks like it, but costs 20x the price. I can't find exact details at the moment, don't have time, but they have to be specially fitted to suit the vehicles pipe work. They are NOT t-bolts. |

Never had any problems with my T-bolt clamps, I'd be interested to know more about all this |

i suppose i should go down and tell craig dyson to take them off his 7 sec car and change them back to garden hose style clams then hey..
your opinion anyway, i just changed to these clamps and yeah they were expensive. If they were 20 times the price they would have been about $170 per clamp. but it didnt ask for any specific thing for my pipe work. You go by the measurements that are specified on the clamps. eg. 82-90mm etc.
Since my tune i have had my cooler pipes blow off twice in 2 days. I went and got these clamps and have not had a problem since. |

170 per clamp is on the cheap side. I've heard depending on size, from 400-600 per clamp to fit them. They hold massive amounts of boost. If you can find a picture of HKS's drag v8 engine, it has them, so does rotormasters 2jz, and any high end 2jz engine. They look similar to t-bolts, but they are far from a t-bolt. T-bolts are cheap •••• that looks nice. |

I agree, to the extent that Ben is referring to Wiggins connectors. Yes, they are significantly better than T-bolts. Yes, they are significantly more expensive. Yes, they are worth it in the drag racing/phenomenal boost setting. I also agree that unless they're seated properly, T-bolts are (IMHO) more prone to leaking than standard jubilee type clamps, and I suspect this has something to do with flexibility. However, get the T-bolts seated right - that is to say, no angles, seemingly even tension across the clamped area - and one shouldn't have a problem. |

I am going to have to stick up for the T-Bolt ones. I have been running 17-20psi on my car for the past 18 months with all different types of standard screw type clamps and had nothing but problems, no matter what I did I would be constantly popping cooler pipes with constant boost leaks  I tried the T-Bolt ones got them on super tight / even and now run 20psi and haven't had a single leak in months, they kick ass.
Rowan, you will easily hear a boost leak, just leave it and see how they go. |

point being, unless your going for a 6 second pass, and running 50+psi of boost, the t-bolts should be fine. |

no point was jubilee hose clamps are 1/2 the price, easier to fit and don't have sealing problems on angles. You confused wiggins clamps for t-bolts. |

those clamps are ok providing there have the rolled edges and are the "constant" tension type...i.e integral spring...
After working on new trucks that run 2 bar day in and day out you soon find out whats crap and whats not.... |

Engine bay looks good Grant. VERY interested to hear how you go on the dyno at track Might be some spots for boostcruising drag day still. Oct 28th Trent & I are racing on that day also
BTW my T-bolt clamps have been fine up to 23psi. Just get cooler pipes lipped anyway and no problems |

Hopefully I will have the cam gears installed and have it tuned by the 28th.
I have given it a few blasts at 19psi and have not noticed any boost leaks as yet. But I will keep an eye on it. |
