Hybrid or Big Turbo

[kelford1988]

I'm looking to increase the power of my TDi Ibiza and the only option left is upgrading the turbo. I have currently being looking at three choices:
1) CR turbos or TD hybrid
2) Allard VT5
3) Darkside developments BT kit.

Are the big turbos worth the extra £1k+ (plus the more expensive clutches, etc.)over the hybrids? As I imagine the Ibiza would seriously struggle to but the power down of the BT even with a LSD.

What realistically on the road is the better choice? As I'm not looking for bragging rights, if I can't actually use all the power and just light my tyres up.

Anyone's experience and knowledge would be appreciated. Especially those who have upgraded from hybrid to BT.

no one?

i personally haven't gone big turbo/hybrid route under the thought of the power in an everyday situation (ie rush hour traffic) it's rather pointless as your never going to use it all, but having been in the passenger seat of a couple of 220bhp hybrid's both with LSD's i can see the point as a fun/weekend car, the performance is mental and more than enough for anybody really

the one time i was in a big turbo'd car it was really laggy, probably due to a crap map, but the hybrid was great with all the added bells and whistles.

have you already upgraded you clutch, intercooler and exhausts etc from standard?

With a hybrid you'll only ever see max figures of around 240bhp, with a BT you'll be able to achieve 300 BT is considerably more expensive obviously!

 

[kelford1988]

cheers guys.
the car has:

Suspension
weitec coilovers
whiteline front arb
whiteline rear arb
rear upper strut brace
poly bushes all round
rear spacers

Brakes
312mm discs and ate calipers
braided front lines
braided rear lines

Engine
Fmic
Green panel filter
Stage 1 remap.

So as you can see turbo, clutch and diff is the next step. Need to decide which turbo and power I'm going to have and for to pick the clutch though.

The cost of bt and the fact that on the road I dunno if I would be able to put down 270+ is my main reservation about it.

What were the performance figures for the hybrids Philosopher? I've heard people say hybrids can match old m3s for pace which would suit me if I actually could believe it.

Haven't seen the 1/4 mile times but the one I was in was pinned to the back end of a boxster s on a rolling start and that had 245bhp with water meth quoted on the rolling road. From the line it's the same problem as with most dervs and bt is launching the car and getting the turbo spooling. The in gear power is the selling point the pull once the car is rolling was well worth it.

about time we had another quality ibiza on the streets of scunny, theres only mine that iv seen post a pic up on here or get a reader ride thread up and running mate and i'll keep my eye out for ya

A hybrid, with a diff and decent driver will do 5.0 to 60 and mid 13s 1/4 miles

A BT car prob won;t do any better to 60, but should be low 13s, high 12s for the 1/4

I'm not sure which M3 your talking about but my BT car would destroy an E36

 

[kelford1988]

@flegz not much to look at mate as its just a PD130 sport on the outside. Should maybe start RR thread for it though just to get some more ideas.

@vroomtshh Thought a BT would destroy the e92 m3 never mind the e36. Was thinking more about a hybrid derv, but based on the numbers you give I'd have thought it would easily keep with a e43 till the top end.

Might just have to get to some meets and see how the hybrid and bt setups run, as they both have pros and cons.

 

[vroomtshh]

I can only compare with an e36 as I've driven one.

I can say that the only car ever to be quicker on the road than my Ibiza is a gtr. I'm sure there are plenty other cars that are quicker, but I've never had a play with them

 

[kelford1988]

Haha if your telling me the only time you've been left was by a GTR then i'd say that's not too shaby.

Whats the performance figures for your Ibiza?

Yeh I got completely destroyed by a gtr before I knew what kind of performance they have.

Current spec is 286bhp/475ish lb/ft.

I'd love to see the spec list for this car

 

[kelford1988]

Jesus that torque is insane. You'd be pulling the tarmac up with that. Putting that down must be interesting especially first and second.

That is a mad torque figure (i would say that car would sit with an Evo FQ400 to 130mph) i thought u would have had more bhp though!!

Explain to me this then - a standard BMW 335d has your 286bhp & 427 ft/lbs Torque, but you have 286bhp & 475 ft/lbs Torque??
So how do you have same bhp figures but almost 50ft/lbs Torque?
I heard before a fella bought a 335d, got a full service etc then paid £400 for an induction kit & top remap.... next day he got it rolling roaded and it read 341bhp & 529ft/lbs Torque - WOW

Its because those are max figures and they wont happen exactly at the same RPM on each car. I didn;t kow a 335d had the exact same power. Learn something new every day.

Basically HP = (torquexrpm)/5252

So by altering RPM in that equation, its easy to see how different torque figures can produce the same power figures, or different power figures could equate to the same torque figure.

I also believe that my car is mapped to produce less power than could ultimately be produced, but I don;t think torque was held back. I'm not 100% sure on this. I know for definite thats not the max power it could have had, but something tells me that was around max torque.

Well fair play to ya lad, that torque must launch ya back into your seat! Has any other diesel ever came close to ya in a race?

I don;t think I've ever had a real play with another diesel TBH.

Other than another highly tuned VAG car, I can;t see it though.

Unless I'm seriously underestimating the 335d

 

[Hyypia]

Well a good going remapped BMW 335d would be around 340bhp & 530ft/lbs Torque with a top speed of about 175mph so im sure it would give you a good race.. Id like to see that 1/4 & 1/2 mile race actually
