Hey guys just wonder what's a good OTR to get and what's some bads ones too stay away from. For a Vy ss ute auto

duspeed otrs are excellent or a ramjet

ive got a VCM alloy otr that i got a mate to paint. good quality and looks alrite Stay away from the PT copy ebay plastic shi t. Some original photos have not been recovered yet.

Nice otr brawlr, and yeh as brawlr said bud stay well away from eBay sh1t a mate bought one for his ve, bad move the thing crumbled and all the **** got in the motor

Make sure it's alloy because those plastic ones concave in.(collapse)

yep my mates got a fibreglass one off ebay(the more expensive of the ones on there) and when u give it a rev it sucks itself in a fair bit, also theres a fair bit of loose fibreglass on the inside that i wouldnt want anywhere near my engine..

ive orderd a duspeed one for my vz maloo seen a few in person was very happy with the quality

ive used/sold like 10+ of the cappa ones and they work a treat just add a k&n filter and your way

those vcm one look the goods now wheres the cheaps place to buy them, tuning shops from this area want 500-600 for them or is the the going money

yeh for an alloy thats bout the prise yella terra have an alloy 1 also looks the same as the vcm for 600 odd bucks but a lot of performance joint use fibre glass ones and if its good quality u wnt have an isue with it at my mechanic they use a real good fibre glass 1 and alot of the cars comen out of there a pumpn out well ova 300 at the treads and there has neva been a issue with em. but like brawlr said stay away from the ebay shi t

I just had a GM alloy one for years. It worked I guess. Destroys the IAT's when stationary due to heatsoak but drive for 3 mins and it back down to ambient. The new breed of Dus and VCM are generations ahead though in terms of fit and finish. As for performance probably a couple of kW's.

Alloy OTR VCM style is 495.00. At idle air temps are high but a quick stab on the throttle brings them down real quick. I have done a lot of road logging and found that at cruise around 80km/h air temps are around 2 degrees above ambient. The VCM OTR is made by a guy called John, He originally designed them for another company many years ago.

So FLASHD whats the best value for money one on the market?

I sold mine not the long ago because I am going turbo. If I bought another one I would HPC, Ceramic coat it. The VCM/ Yella Terra/ HPF/ G&D/ Johny's OTR is very well made. Another thing with the fibre glass ones is the crappy finish on the inside.

i like the the look of the ramjet otr specially in red, there suppose to be made from a good plastic and perform fairly well from wat ive read, vcm seem to br popular choice to and good price

Ramjets certainly work.. had one sitting on the dyno with the fan on while the car was idling watching the STFT LTFT head all over the place.

The one from HPF are suppose to be good. http://hp-f.com.au/catalog/power-pac...power-package/ (http://hp-f.com.au/catalog/power-packages/holden-vt-vz-lsx-v8/g4s310-power-package/) Some original photos have not been recovered yet.

^^thats steedsys car on ls1. pretty sure the hpf otr's are ident to the vcm one

i got a ramjet, cant go wrong. sits perfecting in the girll and no problems in shutting the bonnet.

yer the vcm one looks like the one im gunna go for, that and full exhaust will do for a little while then cam ect and work on the gearbox. whats some mods for the gear box worth doing????????? i know the tune changes line pressure and shift points but i wouldnt mind gettin a hi stall down the track
