Whats the most anyone has got out of a Scoobyclinic TD05 20g? anyone got 400bhp or anywhere near?

 

A std TD05 20G should be good for 400 so i would expect a hybrid or worked upon 20G to either move a bit more air or spool quicker/lower down, or both.

I have no idea what makes the SC 20G different over the std offering. There must be somebody on SN that's using one.

Perhaps if Andy F was about he might know or tell us what makes his 20G different to the std jobby.

 

I know one that made 401bhp on a Newage Wrx wagon at Surrey rolling road mapped by JGM

 

i was wondering would or could it make 400bhp on a 2.5l?

 

If you can afford i'd spend that bit more and get a MD321T and run it at lower boost to make 400bhp

 

your not the 1st person to mention a MD321T i will start having a look someone will have one for sale somewhere

 

also try the sc series of turbos

 

And plenty of others who have struggled to get anywhere near that.

You may get close, but it depends on the supporting mods, esp. a forged bottom end/ new head gaskets and also fuelling.

 

You will always struggle to get over 400 from a 20G on pump fuel. MD series etc is the way to go.

 

 

mine made me 370 on a forged 2.0 with simtec, was hoping for nearer 400 (is an andy f one tho)

was thinking of maybe sending in for an exchange or saving again for a bigger one, expensive either way!!

 

im running at 370 on a 2.5l with a 20g but in the next few week its going to hopefully have 400 but ive been told that many different things. when scoobyclinic fitted it they said it will go to 400 but not much more, then ive been told that it defiantly not go above 380 so a little confused

if was to sell the turbo what is it worth? its done 2000mile

 

how much is the sc tubby??

i bought mine used for 500, was told it had done 8k-ish

 

it cost me £900 when i had it fitted, ive looked on ebay there are some at 250ish but i think these are just cheap crap there was a thread on here about them collapsing inside

 

don't go for those!!!!! cheap for a reason!!!

i only bought used when iwas happy with it's condition/history/originality etc, some people will say never buy used but i'm fine with it.

 

as long as you know what your looking at i cant see a problem, its like saying i wouldnt buy a second hand car

my turbo is near enough brand new still

 

What would you be looking to sell it for? Could be interested at the right price.

 

td05's seem to be a total variable as far as results go, some cars max at 360 some max over 400.

just sems to depend on how lucky you are.

 

the td range i do like, but give good torque levels
for higher bhp levels the md321t is better, i wouldn't say its how lucky you are to get the lower figures, id say its down to the mapper & the other mods on the car. nothing in the car would is luck

if you want the really high bhp levels. the the gt range id be checking out

 

i dont think thats always the case, why does two identicle cars make different figures when mapped even with same mods? in motorsport where every part is checked down to the micron then you should get the same results. there may be internal differences, as far as tollerances etc, but without stripping down to check your won't know, so you have to hope your on the luck side.

 

not really, if you have 2 identical cars. they may be out by the odd couple of horses, not 20/30bhp.

no names here at all, my car was mapped this time last year. made under 300bhp, 287 to be exact, then was mapped by another mapper. exactly the same set up. just a different mapper. then made 317bhp???

that was nothing to do with luck.
that was down to the mapper

but at the same time, the mapper can only map what he has.
but back to the thread, the bigger the turbo. the more ponys you can get

 

think your situation is slightly different, there are known engine issues. also depends where the map origionates, if its a flash and tweeked map or if its a full custom and also how far the mapper is willing to push it.

by saying 20 bhp difference were talking extreams, not just taking two cars for comparison, mine for example ran 259bhp but 280ftlb when it was first mapped thast about on the mark bhp wise, but about 20 up on torque.

so as said its a bit pot luck as to what you get, different cars results vary so theres no gaurenties, if there were tuners would say you get x bhp for x amount of money, but they dont and always come with a message saying 'results vary from car to car'

 

i partly agrea with that one. but the map i had was a custom map

but yes, did get told id get this that & the other.
when you do get whats is exspected, you get a buzz from it.
but when you get under, or alot under, the smile turns to a what the hell!!!

you need to go in there with an open mind, & what a mapper says is kind of hear say till the final result.

these 20g turbos. i dont see the point really for the price

the 16g 330/345ish
the 18g 350/360ish
the 20g 360/390ish

theres nothing really in them
get the td07 for aboth.

wonder what that chager would give?
but, its still down to the mods done. forged bottom end, bigger injectors fueling
headers for the gas flow.

also keeping the engine heat down.
but the turbocharger plays a big part still

 

Any lightly modded scoob will make more power in the winter than it does in the Summer unless you start using exotic fuels and your cooling is properly well sorted in which case you can almost guarantee similar power levels across the year. If your car was mapped in the summer or on a hot day and then remapped again in the winter on a cold day that could more than add 20/30bhp/ftlb.

Conversely the more miles the engine has done the more likely it is to be down a bit on compression from when it was mapped 30K/40K miles ago plus if you've used some bad fuel in the meantime the ECU will have compensated for that, or the MAF may be dirty, Lambda sensor on the way out, the ECU hasn't been reset in a long time etc ect...and you'll be down on power and could easily account for -20 or 30 bhp/ftlb difference.

It's always swings and roundabouts.

 

There was a post/s by Pat Herborn some time ago explaining that two sepearte car running EXACTLY the same engine spec/mods can vary wildly in their held boost/power/torque! (he was speaking from 1st hand experience).

And to add to the confusion, the flat-4 EJ engine seems to be even more susceptible to this than most others!...

 

does any1 know if a tdo5 16g off an sti type ra will fit on my 2002 wrx uk saloon? cheers

 

it will fit but needs modifying to a front entry housing to fit the under inlet manifold inlet tract, after fitted it will need mapping to suit.

 

what you think its worth?

 

so i will need to buy new housing for it or can it be modified? ive already bought it after being told it would fit and now im stuck with it. what would be mu best option now? thanks

 

you can get the housing modified that would be the best option, unless it has already been done? is the inlet straight or 90degree angle.
