hough39 Posted May 23, 2012 Share Posted May 23, 2012 I dont know alot about turbos so just after abit of info on a vf28 turbo, such as how do they compare to a td04/05 power wise, lag etc? Cheers Quote Link to post Share on other sites
Taggy Posted May 23, 2012 Share Posted May 23, 2012 (edited) Pritty much any of the VF series turbos are better than the TD series, the TD series i.e TD04/TD05 are the older generation turbos which were first released when Scoobies started coming on the scene.They were later replaced with the VF series which provided much better spool times and peak power. Although the TD series for this reason are much cheaper from about £50-£90 as opposed to about £250+ for teh VF series turbos.Have a read here/>http://www.scoobytuner.com/tuning/?tSfID1=4&tuningID=43If you can afford it get your self a VF24 if not go for a TD04, a TD04 on a 4e engine will perform great at 1 bar, lag is about 4000rpm, TD05 will be nearer to 5000rpm Edited May 23, 2012 by Taggy Quote Link to post Share on other sites
hough39 Posted May 23, 2012 Author Share Posted May 23, 2012 Ah Right cheers for the info mate, well I'm currently running a td04 on a forged n cammed 4e 281bhp at 1.4bar! Plans are to get a custom inlet Mani and bigger turbo to try get 300+bhp but without turning it in to a lag monster so which turbo do u think would be the best for this?

Burny Posted May 23, 2012 Share Posted May 23, 2012 VF series would deffo be an improvement on TD04 however the ultimate turbo would be a garreth GT28 or GT30 as u may be aware, you'll make well over 300bhp its just the cost lol *Garret Quote Link to post Share on other sites
mattyD Posted May 23, 2012 Share Posted May 23, 2012 *garrett ;) Quote Link to post Share on other sites
hough39 Posted May 23, 2012 Author Share Posted May 23, 2012 i know mate but looking for a turbo that will fit my current set-up really Quote Link to post Share on other sites
Burny Posted May 23, 2012 Share Posted May 23, 2012 *garrett ;)My bad lol cant spell it because i cant afford it !i know mate but looking for a turbo that will fit my current set-up reallyThen look into VF's. I lo Quote Link to post Share on other sites
Burny Posted May 23, 2012 Share Posted May 23, 2012 I loOked into it myself theres a good range out there such as VF22/28/34/35. In the end i just picked up a cheap TD05 for my 5E if i het bord in the future im going to save for a GT30 and add an inlet and 3" exhaust Quote Link to post Share on other sites
AdamB Posted May 23, 2012 Share Posted May 23, 2012 VF35 will see you over 300bhp Quote Link to post Share on other sites
Azz Posted May 23, 2012 Share Posted May 23, 2012 If your running a standard engine at 1bar with td04 and you swap to a vf 22/28 would it be as safe ??are the vf series more powerfull so it would blow something ????? Quote Link to post Share on other sites
AdamB Posted May 23, 2012 Share Posted May 23, 2012 well I'm currently running a td04 on a forged n cammed 4e 281bhp at 1.4bar! The VF series are just ballbearing versions of the TD series with a few minor differences. The VF series will flow more than the TD series. Quote Link to post Share on other sites
Amjad Posted May 23, 2012 Share Posted May 23, 2012 I'd have thought at the same boost pressure it would be safe as long as it's fuelled properly. Eg CT9 at one bar puts out a lot more heat than TD04 at 1 bar so TD04 is safer? Quote Link to post Share on other sites
AdamB Posted May 23, 2012 Share Posted May 23, 2012 Not really Amjad, because the TD04 will flow more air (CFM) than a ct9 at 1 bar. So to add to the extra air, extra fuel will need to be added to compensate for the change. Quote Link to post Share on other sites
Azz Posted May 23, 2012 Share Posted May 23, 2012 Soooo the vf and td will be just the same safewise??? but vf will have less lag Quote Link to post Share on other sites
daniel_g Posted May 23, 2012 Share Posted May 23, 2012 ^ I think so mate, but i reckon vf35 is more laggy than td04? Quote Link to post Share on other sites
Azz Posted May 23, 2012 Share Posted May 23, 2012 ^ I think so mate, but i reckon vf35 is more laggy than td04?ye im just thinking would it be ok to swap my td04 for a vf 22/28 and weather it would increase/decrese hp and safety. Quote Link to post Share on other sites
AdamB Posted May 23, 2012 Share Posted May 23, 2012 No matter what you do it needs to be remapped to be safe, you can't just bolt on items and expect them to work to their full potential. Yes it will be safe but I wouldn't advise going balls out until its been checked/remapped.The VF35 will be more laggy than a td04, but you have to trade off spool for power. You can't have one without the other or you'll have a really unbalanced turbo, which is why the garrett GT2860 is such a good turbo, has a great size turbine coupled with the perfect compressor.

Amjad Posted May 23, 2012 Share Posted May 23, 2012 I know it flows more air, but as long as the fuelling is spot on isn't a TD04 safer on your engine long term? Sorry for the hijack! Quote Link to post Share on other sites

mattyD Posted May 23, 2012 Share Posted May 23, 2012 My bad lol cant spell it because i cant afford it !are you sure with the amount of funds your spending on her? ;)back on topic, if you can get a decent one the vf34 is the one to go for Quote Link to post Share on other sites
AdamB Posted May 24, 2012 Share Posted May 24, 2012 Yeah it will be safe on a stock engine if the fuelling is setup correctly But the more boost you run the more likely it is going to cause failed ringlands, because most stock engines are rather old and done a fair few miles, the ring's won't seal as good as what they did when the engine came out the factory. So there will be more gas passing under the piston rings. Quote Link to post Share on other sites
Bean Posted May 25, 2012 Share Posted May 25, 2012 The VF series are just ballbearing versions of the TD series with a few minor differences. The VF series will flow more than the TD series.not all vf turbos are bb.my mate has a vf28 on his stock 4e with a race tech inlet it makes 252bhp at 1.09 bar. its a good turbo and just pulls harder and harder. you really need to rev it out and bounch of the limiter a bit to help keep it going though.a vf35 will spool slightly later than a td04l but make a good bit more top end. mines making 324bhp at 1.55 bar on a 5e. theres loads of info and builds, dyno graphs for different vf turbos about on the forum now.

Browner Posted May 25, 2012 Share Posted May 25, 2012 Mate research a VF30 turbo I ran one on my car. It spooled up like an animal as it has the same size back housing as a td04 but plenty of power up top. It will pull like a train! Quote Link to post Share on other sites
