i had an opcon that had internal compression, far more efficient than the eaton with much lower discharge temps
New eatons including the HVT1900 have a twisted lobe design (140deg iirc) so they build boost internally and do not suffer the same heat problems as earlier models.
They are close to twin screw now. |

The TVS rotors still push air around the outside of the housing and don't have internal compression like a twin screw.
They are still a roots blower, just a 30% more efficient version of the M90.
According to a thread on LS1 forums there is reported a situation where the TVS was more optimal over a twin screw.
Either way this is a fantastic result. |

All eaton superchargers including M90's are positive displacement supercharges.
My bad Damian, letting my fingers do the talking before my brain had engaged first gear.
Even though the old Eatons aren't that efficient the new TVS one's are a huge improvement
Excellent results for Nathan |

G'day all,
thanks for all the positive comments.

Hey Damian, I am not familiar with this thread myself, though I may have mentioned this before, Bullet did back to back testing with the Whipple 2300 and the HTV2300 for their Hemi kit, and the HTV produced 70 rwhp more than the Whipple under the same conditions.
As for what I will do now, I think the 300rwkw mile stone is too close to pass up, so water/meth and 14psi should be done in the upcoming weeks.
Stay tuned,
Cheers. |

This is a huge difference and somewhat a suprise but not impossible.
One of the problems with twin screws type blowers is there peak efficiency range is very limited and they have to be very well matched to the application, where as the roots efficiency is very similar over a wide range of air flow rates and pressure differential.
For low boost applications below 10-12psi the TVS blowers do appear to be more efficient but from what I have seen at high boost the twin screw is still the better option. |

Nathan,
Great results well done.
What diameter pulley are you running on the SC?
Do you have a print out of the torque curve? |

Hey Damian, I think you might be on the money. Those results were on 8psi I believe.

Thanks for the comment Andy. From memory it is fitted with a 65mm pulley. It was originally a 70mm which gave 12psi with standard heads and cams. After the heads and cams were fitted, the boost dropped to 8psi. So 5mm difference, equates to 3psi and 25rwkw on my setup.
Here is the Torque curve.
The peak is not what I expected, however this may be due to the fact that this was with the auto diff. I think that if the final drive was suited to the W58, that the figure might be more respectable.
Either way, I am quite happy with how flat the curve is, I think this is more beneficial than a torque curve that peaks high, then drops off rapidly. |

Thanks Nathan,
Just trying to get a feel for where my engine sits and if it is worth pulling the heads off, porting and fitting cams.
How many extra kw's would you estimate the 32 set up takes to drive? To me it looks very power hungry.
Chris managed 272 kw on a sock engine in his hilux running an 80 mm pulley at 9psi.
My set up is a completely stock engine with a ported Richwood manifold, TVS 1900 and a 75mm pulley (11 psi). I don't have a dyno print out as it has only been street tuned at this stage with an Adaptronic ecu. |

Thanks Vinny,
Yeah I am very happy with the result. I was going to get Bullet to continue working on the engine, but I have decided to get it transported up to Darwin so I can get some use out of the old girl and rebuild the suspension along with some other bits and pieces that need to be done. Once it gets up here you should come and check it out if you want.
I think that late 2010 I will take it back to them to rebuild the engine and try and crack the 400rwkw mark.
Cheers, Nath. |

G'day all,
Well just to let you guys know, the Soarer turned up on Friday. Unfortunately it arrived with the drivers side door hinge stuffed, so the door wouldn't open without unbolting the guard and pushing it in.
I haven't been able to open it up too much yet, but a quick run around the block and I'm quite happy with the results.
Aaron and Vinny, PM sent.
Off the line it's a little bit sluggish (without dropping the clutch), I put this down to the cams and the fact that it still weighs 1700+kgs. But at about 3500rpm it really comes to life! But then I've had to slow down again, so I'm looking forward to really winding out.
The exhaust note is really different now above 3000rpm, has quite a bark to it. I'll have to get someone to have a listen and see what they think. The short drive I went on it kind of reminded me of one of my mate's V6 Commodore which had stainless extractors and 2.5 exhaust.
Hopefully someone can reassure me that it doesn't.
Well the plan now is to get it back on the road, rebuild the suspension, struts, bushes the works. Upgrade the exhaust to a 2.5 mandrel bent system, get the 14psi pulley from Bullet and water/meth injection. This should hopefully put me well into the 300's.
I'd like to thank Bullet Cars, Greg Markham in particular for all their help getting this together. If anyone has any questions regarding the setup let me know, hopefully I can be of help.
Cheers,
Nath. |

I like it !!! A very tidy install,
especially the intake plenum being straight !! But the best is the colour of the car !!! (Spotted the extra injector real quick)Very nice !! Recon it would have to be up there with the best for looking like it was ment to be there !! |

Good to hear Nathan!
Regarding the exhaust you are planning:
For the love of GOD, do NOT go to D&T exhausts for ANYTHING that involves your car!
Im just concerned you might have seen one of the ads on telly and thought about going there.... 
I got them to make up a dump pipe. They bolted it to my gearbox. The end. |

For chassis stuff: Custom Fabrication, Toupein Road, Palmerston/Yarrawonga. They are always busy unfortunately
For performance, Dave at Hi Tech Tuning in Marlow Road, Berrimah. Performance is a bit hit and miss though in NT. DIY is longer, and harder but at least you kinow its done right
PS: Looked like you were doing well in the wet on Sunday. That VE GTS has some straight line stonk huh? |

Dave used to do the tuning on my Rx-7. I am told he is back in his old place again. Thanks for confirming it.
Sunday was a lesson in car control. I had no problems staying alert! Man it was slippery. I think I did a 1:36 in the wet- I'm waiting for the results from Natsoft. |

Hey Ben, it would appear so. Seeing as though you were the last to post on my thread! Hahahaha...
It was good to meet you too Mate, what are you up to this weekend? If you are keen to stand around an open bonnet, drink a beer or two and talk shop, I'm in

So just saw it's been almost 12 months to the day. Where has my life gone?!?!
So as some of you may know I have been tied up with the suspension rebuild along with work and trying to find motivation, things are really dragging out!
So I have made the goal to get everything done and the UZZ32 on the road (and even registered!) before the wet season.
So during this time a family of rats decided to nest under the intake manifold!
So whilst that was being dealt with, I ordered a new top plate as Bullet Cars had made an updated to their production which includes an O-ring seal rather than sealant.
You can see there was probably some blow by at the rear of the supercharger mount. I doubt it would have been significant but deffinately there.
Other items in this area have been individual water injection setup, still not complete as it is proving to be a bit of a headache to get how I want it.
A new supercharger intake larger in diameter and will take 2 throttle bodies.
Plus larger intake piping connected to 2 Apexi filters.
All of which are taking up the spare room with other car stuff just to impress the missus!
I'll try and get more pics up over the next few days.
Cheers. |

Definitely get water injector or an intercooler if you plan more than 8psi (ish)
No sure what boost you are planning on running, but without help, at 11psi the intake temps will be around 70degC, on a cool day, so getting up there. |

Hey Andrew,
Have you read the rest of this thread? As such I am not sure what you are getting at. Whatever my intake temps are I believe water/meth on my setup might see up to about 40rwkw. And if you can find me an intercooler setup to suit be my guest!
Anyway, I have been trying to find my data logs to check intake temps and the injector duty cycle but they must have been lost when my hard drive fell over.
But I can say that I have no ignition modification at all and fuel modification up to 190degC for intake temp.
I'll get some figures in these areas before and after fitting the 15psi pulley and the water/meth.
Cheers. |

Sorry Nathan, should have re-read the thread to jog the memory.
I'd be interested to know the intake temps at 12psi? (or was that the 190degC you were hinting at?)
As for the intercooler, Bullet do a bolt on WTA setup, goes between the manifold and the HTV1900
40mm thick.

Hey Andrew,
All good mate. I'm trying to jog my memory also. I think you might not be too far off though with 70deg. I can remember that Bullets WTA intercooler will bring intake temps back to ambient at somewhere around 10psi.
They have a new design now where the cooler sits inside the manifold by 10mm I think. It would still require about 15-20mm bulge in the bonnet to fit though as I only have about 15mm clearance at the moment with the current pulley.
The 190deg is the max temp on the Wolf, not the temps that are reached. I would take a guess of about 60deg as when talking to Greg, I think he said there was about a 30deg temp drop with the intercooler. Even after heat soak into the water. Mind you I believe there is allot of plumbing involved including efficient heat exchangers etc.
I wanted to fit the water/meth as is to crack the 300rwkw mark but a 15psi pulley was allot cheaper but now it will probably all happen at the same time, although I will use the second MAP for loss of water, so I'll be able to get an idea of the gains from the injection.
Well I'll keep you all posted.
Cheers. |

I'm surprised you had the balls to push 15psi without intercooler and water meth! respect!
Will be watching this as you get it all running again. |
