I've heard some good things about the AndyF hybrid TD04 turbo, including a current post in this section and it's something I'll look at when I change my TD04 later this year.

Can anyone tell me a bit more about it - what's changed from the standard TD04, is it still a reliable unit, what are the power/boost gains, what's the advantage benefits over a VFxx unit, etc?

Thanks.

 

Might be best to ask the man that makes em....

As my Sti has destroyed 2 VF's in 9 months I wouldn't advise one of them, they seem a bit fragile to me....

Now running a TD05-16g from AndyF and no complaints yet (except for the overboost) but it's not been remapped yet, which should resolve that.

 

Thanks Ron, I've read the following info on Andy's website and it sounds like it might be the way to go. I want to achieve ~300bhp and more importantly, 300lb/ft+ and the TD04 hybrid is more than capable of that, (I intend remove my remaining cats as well).

AFP4H – is based on a TD04 this is available new or fully re-manufactured on an exchange basis. It is fitted with a new high efficiency, high flow rate compressor wheel and compressor housing which is capable of maintaining the fast spool up rate typically associated with the TD04 but with the ability to run higher boost efficiently over a wider rpm band. This turbo has been tested to levels in excess of 320lbft and 320bhp. With full boost still coming in as low as 2500rpm on a 2.0

£400 exchange or £670 new outright (includes 12 months warranty)

 

The VF turbo's work very well, and it's very rare for one to fail, unless it has an oil supply problem, is run beyond it's limitations, or has a naff air fitler !

If you keep breaking turbo's, I suggest you look at what's causing it, because it's not the fault of the VF turbo.

Had my VF23 hybrid on for 10000 miles after a 2.5 conversion running 1.3bar max. Still going strong...Think it would produce the sort of figures you are looking for.....best asking the experts.

 

What about lag with the VF's, I like the fact the TD04 spools up early and there is boost available a <3k rpm's?

 

andys hybrids are quality turbos, im on my 2nd one now and thats by choice

 

when i had my 20g turbo i was talking to andy and he told me his newage car with hybrid TD04 would give my classic shape a run for its money my 20g would only outperform it on the straights where it would invlove lots of waving

 

Thanks for the info, sounding better all the time. Anyone else got anything on these?

 

Rich I'm starting to get worried about you

 

I like the thought of 300/300 (plus), that's all. No need to worry Kev

 

AFAIK Andy might be on his hols for a few days so he might not reply tonight !!

Midlife.....

 

hes already back..................

 

Rich -

This is the route i'm thinking of, £400 can't be knocked for that kinda performance!! Def don't want something that doesn't kick until 3500rpms and anywhere around the 300 mark suits me fine!

De-cat this year, turbo and re-map next (thats the plan!)

Don't suppose the £400 includes fitting (prolly pushing it i know!)

 

Have an AndyF 20g on my tweeked Sti v3. Raced hard without mercy to 8000 rpm/rev limiter..Andy garanteed it under those conditions.
It is running brilliantly, delivers well especially if you keep things buzzing over 4000 rpm.
Tight fit into the space available, full installation details on my engine thread in Projects, read the first 5 pages or so.

For a road spec car with mid range torque and low rev spool you might want to try the 18g(based only on what i've read), but always talk to Andy about your application.

He truly is a Wizzard on this stuff.

I will be getting my own taylored 20g for my 2.5 soon from Andy

 

Would this turbo be good for 350 / 380 bhp???

chrissy

 

For that level of power, the TD05 18g would be ideal. They are readily available, and can be setup for your specific requirements from a number of traders in the UK. It can make full boost before 3500rpm, some cars as low as 3000rpm (depending on cams, exhaust, inlet etc) and can make 380hp on optimax fuel (no octane booster).

Andy97:
Your car was under wraps at API!
Hope you have a GOOD gearbox for that 2.5!

Graham

 

Nope, but I think I'll need to start looking for one after its run in. Fancy a ppg gearset, but I'll need to listen and have a ride in a car with one fitted to convince myself that they arent too noisy. Car will be a dual purpose for maybe a year or two.

Question - Paul @ Zen will a ppg helical set take 400*400 all day every day in a 752 case?
Andy

 

Graham

Was the new block in the car? This is terrible, Its like being 5 years old again and waiting for your long awaited birthday present.

Andy

 

Yes the helical ppg set will take 400x400 all day long in a 752 case.

 

Hi mate the cars a 53 plate UK STI was just thinking that spool up at 2500rpm would be just right but 3000rpm dos'nt seem bad either cheers mate

chrissy

 

That depends on what you call "spoolup". A standard 53 plate uk sti makes full boost around 3500rpm. An 18g will spool as quick as the standard VF35 turbo, will make more midrange and peak power and when combined with a decat full boost can come in some 3-500rpm sooner (which will be the case for a standard turbo). I recently fitted an 18g to a UK sti, which had a number of supporting mods and it made 390hp and 380ft-lb. it was every bit as driveable as the standard turbo, and made that power at a paultry very reasonable 1.4 bar (although it ran more boost in the midrange), although I would say this is at the "good" end of the scale.

Paul

 

Andy, I think the block was in although i wasn't told that.

I would think a Zen box with synchro change would be plenty for the car.
Graham

 

Thanks for the feedback guys

If anyone PM's, emails or phones you offering you a cheap "Andy F" turbo, let me know will you

cheers

Andy

 

By the sound of your post Andy you've had one stolen (or maybe more)

 

Not stolen in the physical sense

 

Sorry mate took it the wrong way
