has anybody achieved 300bhp with a TD04 hybrid on a blobeye wrx?

if so what supporting mods were used?

reason being my turbo is using a lot of oil and smoking so time for a new one, i can get it hybrid for £350.

i would like 300BHP and roughly same torque would make for a cracking quick road car with the fast spool and wouldn't put much stress on other components/engine.

thanks in advance for the replies lads!

Think they're rated at 290-310, IIRC Andy Forrest's website correct. So 300 is slap bang in the middle.

Pretty certain some have attained that figure.

cuprajake has recently had his mapped. But I think he had a road map (no dyno printout). He did say it was much more responsive than his previous VF34 (as you'd expect), and was v. happy with the results.

See the penultimate post, #182, in his thread:

Cheers joz8968 will have a read, going to phone the company up tomorrow and have a word about what is achievable with there hybrid.

also would the standard injectors be fine at that BHP?

obvs will be the usual full decat, fuel pump and a 3 port boost solenoid, no point in wasteing money if not needed.

Yellow 440s are good for about 325-340bhp.

Your car has at least those doesn't it? Or does it have pink 505s? Not clued up on New Ages so much.

jf12345

they are 440cc standard i bought some second hand "pinkies" last week 550cc but if i dont need them i may as well sell them, just had a read at that thread seems like for a normal daily car around town that the hybrid wins, i was originally going to go for a VF35 etc etc but alot of people i have spoke too have said stage 1 and enjoy it for reliability i dont want to spend ridiculous amounts of money.

Yep just done mine, used turbo rebuild, £360 11 wheel impella with machined housing.

Car has harvey up pipe, i ported my headers and wrapped the lot, 3" full decat with a raptor exhaust, then some sti injectors.

When i got the vf34 i was happy with how well it pulled. Vut through town driving found it really laggy, the hybrid is amazing, spools so quick, and up till 6k does exactly what the vf34 was doing.

Interested in this thread. Ran a vf28 with pinks and decat etc mapped at 336bhp on my uk300. Still on td04 on my blob with decat and andrew carr map. Car drives spot on and feels just as good as my uk300 even tho id be lucky if im running 280bhp. Im looking to upgrade to a vf35 and pinks but from this i think a hybrid td04 might be worth looking at as i dont do the traffic light g.p but do like the odd day at curbrough sprint track where a td04 seems well suited.

jf12345

just a quick update, i couldn't get hold of anyone in my local area to hybrid my TD04 so i instead went for a 2nd hand VF35 thats not long been reconitioned done just 40 miles and sat in a guys garage! will be getting it fitted and mapped in a couple of weeks, cheers for the input lads.

Talk to Craig Bellworthy at Central Turbo's in Derby. Been building turbos 20+ years and does a 19T TD04 for around £450 as well as big wheel 16g, 18g, 20g TD05's and billet/rebuild options on VF turbos.

of Bob Rawle I got my afp 04-h hybrid mapped to 310 bhp.

The Afp 04-h is the best turbo I have driven, so responsive low down and just goes on and on pulling. I use it on my 2006 Hawkeye for daily use and no issues after two years of running. It really makes an exciting road car with such flexibility low down and no lag that I can make out.

Only problem is that Andy F no longer supplies them.

Neil.

Neilfrank

torque is 388 lb. Awesome from Bob.

Sc32 is a TD04 hybrid I believe, either way good for up to the 320 mark with the right supporting mods.

Vf 35 isn't really suited to non avcs heads, it's laggy on an STI so it will be even worse on a WRX, think nothing until 4k rpm, which is why STI owners get rid.

neither is the vf34 haha

Out of interest where'd you get your turbo? I'm looking for similar

Turbo rebuild fleetwood way

So you're saying that vf34 and vf35 are quite laggy on a ej205? So at what rpm do you expect full boost?
And how situation looks with td04 hybrid? When do you expect full boost to hit?

SmurfyBhoy

You will never make any real usable power below 3000rpm with these engines,

Can have all the boost you want just nothing will happen as way outside its efficiency zone

Claiming to make X amount @ 3k looking at a dyno graph is totally different from on road @ 3k and plant foot,

From all the graphs I’ve seen and compared, a TD04H makes more torque/power and is more responsive beneath ~3250rpm, at which point a VF34/5 will out perform one throughout the rest of the rev range and continue to pull past 6k.

Port & wrap the exhaust and up-pipe and clean up the wastegate on the VF series and the differences are even less.

If you do a lot of low speed City driving and don’t get much opportunity to WoT, then the TD04H will make for a quicker car.

uxon

What you mean by 'real usable power'? I think that having ~200 ftlb of torque at 2500rpm would be good enough Is it achievable even with stock turbo? There are some misleading info about that. Some say you can reach 1bar of boost below 2500rpm with a good tune and supporting mods, while others say you will not see any noticeable torque below 3200-3500rpm.

TECHNOPUG, I found many posts in which you were wondering about best everyday turbo. Have you finally managed to put td04 hybrid into your car (or any other turbo)?

SmurfyBhoy

Can make all the boost you want but if engine can swallow it will be no use,

With a good tune and some crossed fingers you might just get 200ftlbs by 3 grand if you have floored it from 2500rpm lol,

If you want to make power close to idle buy a diesel,

No not yet. Life keeps getting in the way. I have a TD04 that I have partially stripped and I have all the other supporting parts. What attracted me to the TD04H was in part building it myself and effectively having a new turbo. That's something to consider when comparing TD04H & VF results; the Hybrid turbos will almost certainly be rebuilt and as new, as opposed the second hand VFs which could have any amount of wear and not be performing at optimal.

I doubt very much that you would be disappointed with either turbo if properly set up. I imagine that you'd really need to test them side by side to definitively choose one over the other.

One thing that I've observed is that the vast amount of day to day driving (excluding M-way) is at around 2250rpm. So a turbo that is up and running by 3k would make for a great, flexible daily drive. Much later than 3k (especially on a WRX) would probably require a down shift first which is less than desirable.

You could get over 300bhp with 850cc injectors and bio ethanol at 20%
