Any news?

any pics off new turbo on the car?

Rod-Tarry

2 days running ive forgotten the camera .

Can report the car is now complete , the undertray going on for the first time in 4.5 years. Didnt do any mapping today as Mark was working on other cars & we now dont have the Monday deadline. Taking the weekend off as I need a rest been a busy week.

jameswrx

Got a lot of respect for you doing this!

At 65 most would be laid back in a green velour recliner, snoring with a glass of brandy in hand and John Wayne blasting out on the TV

Rod-Tarry

Opps!!!
Had a phone call from Mark today he wanted to get some mapping done before a Topspeed run on Thursday (Insurance probs sorted) .
As soon as the run started Mark was taking huge chunks of fuel out & the car was fast but not silly. We were able to map to 2.8bar & also add ignition not possible on the road with the GT42RS. The car was slower at 2.8bar on the Borg Warner than 2.3bar on the GT42.
All we did was change the Turbo so its the Turbo thats the problem.
I had purchased an S400SX with 1.1 exhaust but it now appears thats not what we received . Its 18 months ago so no come back.
Its my fault it was Speced in the States & purchased by me as a direct replacement for a GT42RS & capable of making more Power with better spool. Mark has measured everything & we now know that what we wanted was never possible, lack of knowledge from the States mean we have a brilliant 700+ Turbo but not one that will puff past 800. I asked for a T4 fitting not a T6 & after looking at the website that means a smaller exhaust wheel & it becomes a S400SX/3 not a S400SX.
Haveing driven loads of these cars we both agree the BW is 650 fast at 2.8bar & the GT42 is 730 silly at 2.3bar on pump.

We are glad that the lack of horses was found today & not next Thursday during a Topspeed day.
We are now undecided what to do, we could go back to the GT42 but need the car for ND so it will be after after that as their are a few mods to undo .
The new Garrett billet looks tempting at this point so maybe development is not over yet.

Greg will get fed up polishing his helmet .

What a pain that is Rod. 2.8 bar though ha

Greg is a helmet he's looking forward to smashing the records Rod !! We are going to feed him a good tandori the night before so he gets the urgency

Rod-Tarry

Thursday is deffo off as no point going with 100bhp less on race than we require. It is being looked at over the weekend & a decision made on Monday, heard from him a few times this afternoon so fairly sure i know what he wants to fit .

Its Dave

GT42R and 200 shot of nos and just go for it!!

Jay,

Probably a good thing that I had to cancel Brunters etc yesterday, I'm lead in bed with a temperature of 102, feeling like death, man flu.....

Rod-Tarry

Going with the GTX4202 with 11 blade wheel using GT42R exhaust housing as its far superior to my GT42R. Borg Warner now up for sale.

wozzy

sorry to hear the bw was no good for your application rod. Can i ask though what you/mark thought of the bw turbo itself compared to say a gt40 ( or whatever garrett equivilent is ). ie drivabilty, spool, transient boost recovery etc.

Does extended tip technology live upto its hype or is it better to stick wth the tried and tested garretts???????

warren

Rod-Tarry

We didnt get into spool etc, the lack of grunt was obvious so mapping stopped there. My first impression, if it has better spool its only marginal not night & day.

wozzy

cheers. good luck with the next one!!

Rod-Tarry

Well Turbo is ordered from Australia, no stocks in UK & expensive from the States if you can find one . We live in a crazy world when its mega difficult to buy something thats advertised everywhere. Should be here by Monday so hopefully we will be testing shortly after that.

Relaxed this afternoon with a few hours in the garden. Its then I realise ive given way too much time to my car over the last month or so. Will spend more time in the garden tomorrow before sorting out a wiring problem for Mark on Thursday. RELAX !!! .

Rod-Tarry

The Turbo has arrived from Australia . Not seen it yet as ive Annie's brother over from Canada & thats my priority at the mo.
Below are the maps comparing the old with the new .

Big Will_

Crikey! That compressor map looks phenomenal! What is the target boost to run on this new turbo Rod?

Very best of luck with the end goal, you've certainly done the development and fingers crossed it'll reap the rewards

Mark Shead

As much as it needsbut target is 2.5bar and maybe a bit more.

Mark

you know full well it will be at least 2.8 bar

Rod-Tarry

A pic of the new Turbo.




& how about this baby, Marks new Turbo of choice up to 700bhp.

GaryHurn

iTrader: (1)

nice compressor map

what turbo is marks new favorite??

wozzy

a variation of the bw 400sx i would think for 700bhp??

turbotoaster

doesnt even look like a s400 rod, from that picture i would say its a s300-63 which actually is rated to around 700bhp which makes sense that your maxing it out in the 600bhp range.

didnt you check the compressor wheel sizes when you bought it?

MAD Ade

iTrader: (1)

What picture are you refering to? If it's post 423 that IS the GTX42R202.

Rod-Tarry

Your now confusing even me .

The Turbo that didnt make the Power is a S400S-3 it was sold as a S400SX (gt4202 replacement) & clearly wasnt .
The 1st picture on post 423 is a GTX4202
The 2nd picture is a s300? which Mark will use up to 700bhp it has nothing to do with my car .

macca33

Is the car going to make more power again?

Rod-Tarry

Well it wont make less thats for sure . It could be pushed past 900bhp im sure but Mark wants to remain safe on ignition but at the same Boost it will make more Power than the 838. This Turbo can puff 3bar all day throughout the rev range but im sure 2.8bar will be all it will be asked to produce. We are limiting Power anyway so not too interested to see what it maxxes out at.
Setting a record approaching 215 requires lots of Power so thats what we are aiming for. It has 2 chances it will or it wont .

turbotoaster

the second and third picture is a s300, which is a much smaller turbo, you can tell straight away buy looking at the compressor housing and wheel

this is a s475 turbo



you got the completely wrong turbo, im guessing either the boxes were mixed up buy the seller or you have been conned, if you had got the proper turbo you would have seen the expected results lol.

unless you fitted a turbo to your saff thats not the same as the picture you have there.

for reference a s475 in the uk has already done 703bhp@1.8bar which is the same as 937bhp on a piston engine

Rod-Tarry

I know exactly what Turbos I have . Please read before you say things like you have . Of course the S300 is a smaller Turbo I state clearly its not my Turbo .
I do not want the Turbo you show cos its a real dog, we are following the testing of these in Australia the 300 series work the 400's dont or as are tester said its a 'goat'. All big Turbos make the Power its how it does it that counts. I made the error of believing American bullshit on the 400's.
They are not comparing well with the new Garrett GTX42 series so thats why we have changed direction. Getting the best is about development & thats what we are doing . If mistakes are made we discard those parts & then finds one that actually works.

SiZT

Not sure if you remember what I said to you at Trax about the B/W.

Interesting question, was your s400 an "airwerks" turbo or generic B/W

Rod-Tarry

Airwerks

turbotoaster

ok sorry rod, your saying the picture was not the turbo you tried on the saff?

you mentioned the turbo you bought came with a smaller turbine wheel, the smallest a s400 comes with is a 83mm turbine wheel which flows 100lbs(1000bhp) of air hence im not sure what you have had delivered, a friend fitted one recently with a t4 rear housing and that had a 83mm turbine wheel aswell.

the gtx series is better than the normal ETT, but thats why bw produced the ET-R series wheels to compete.

Im just unsure what you actually have because other uk people are getting the expected results

Rod-Tarry

Your wrong mate ive got one on my car its deffo a S400 be assured.
You dont have all the facts only believing what the internet tells you.
There are two types of T4 flanges one is called the 'full Race' & wont fit a Cosworth its 1" taller, we were sent one to try & indeed it didnt fit. The GT42 'copy' they produce does however fit & that comes with a 74mm wheel .

turbotoaster

he must have the 'full race' one as you call it then, being a rotary he had to have a custom manifold made anyway and the 2 companys that sell that turbo both said it comes with a 83mm turbine wheel, we ordered it and that was the size that came, didnt realised they can fit a tiny turbine wheel to it aswell.

ill be running a 1.1 a/r t6 on mine so wont have that issue, shame you couldnt run the full sized jobby but then its the cost of making a new manifold again!

Rod-Tarry

Shame , bl**dy annoying is the word . Its totally mucked up our Schedule. I was due to run before haveing Annies brother over from Canada & hes here for another week so cant do anything till after that.
Their is a Vmax before the months end that ive entered but that looks a bit tight now .

I wanted to run 'balls out' in a mag for 213 & try to beat 207 off gas at Vmax.
We should now have the Power to do this or get very close.
Will be very annoyed if the weather pushes this into next year, really do want to finish this caper before years end.

turbotoaster

after all your updates recently i was expecting you to get yours run much earlier than mine but wit the issues you have had i might end up being pretty close to you, got my fia approved seats coming next monday and then ill be doing my turbo setup, managed to get it all costed including custom manifold for £1k so pretty happy about that!

It will be interesting to see what the new billet comp wheel does for your car and see if it matches the impressive comp map they have been showing off, i know someone who went from a 4202 to a 4294gtx and gained 30whp so will be good to see your results

crumpet

imo a t3 would make more power than any of the turbos above at 15 bar
