My single turbo pics and results!

[rajvr497]

Just tought i would share some pics and the results of the single turbo setup i did for a friend.
380HP ATW @ 392 FT-LBS TQ @ 20psi boost

Garrett t3/t4 journal bearing turbo
Tial 44mm wastegate
2 rear stock manifolds ported
2'' runners.
aem water/meth kit
evo 7 injectors

Had to stop @ 380whp due to spark plug blowout.
did a re-gap now its on 22psi so hopefully we are on the 400whp mark!!

I can't see the pics what ecu are you running?

[Nick Mann]

At the wheels? Strewth!

[MarkSanne]

Wow!!! Awesome!!!

[Davezj]

they are some great results, 380hp at the wheels, which meas the engine is makeing about 430-450hp at the fly.

i do have a couple of questions though.

did you have any issue with the position of the MAF, with a cone filter directly on the input. do you get a reliable air flow mass measurement.

how are you monitoring the engine?
are you measuring AFR, EGT, coolant temp, oil temp, or just using the AFR.


i would like to see some print outs of the dyno run just to see what the power and torque deliviry is accross the rev range this type of single turbo conversion gives.
i would presume it is all top end 5000rpm plus. so a print out would be good to see.

I second @Davezj - I wanna see graphs to see turbo response

First thought is, if there's notable lag, could a sequential system be built to use a single (or perhaps both) TD03 just to get the car moving?

(Brain is already racing thinking about control valves to help build boost like the sequential systems in Subaru's)

[Davezj]

it will be interesting to know if this setup with filter on the front of the MAF works well at low air supply as well as high air supply. being able to remove the air box will give me a lot more scope for the TD04 conversion inlet pipework to the turbos.

here is the dyno printout guys.....
AFR/KNOCK/COOLANT TEMP ETC was monitored trough evoscan.
At this point we started getting spark plug blowout as shown on the dyno graph at about 5500rpm upwards....
did not have enough time to gap plugs and go again.The car now runs 22psi after gapping the plugs the other day smooth.
Everything was done by me including the tuning!

Will visit the dyno soon again after some more mods!

Not bad at all

A few questions please:-

Why are you still using the MAF ?

What size compressor trim option are you using ?

Is the engine internals standard ?

Any head work done ?

What plugs are you using ?

Are they standard coil packs ?

Any plans for modified plenum ?

Could you not use a bigger wastegate ?

[rajvr497]

Sure Steve,in order to run the system without a MAF would require a full management and we just didn't have enough cash so we stayed with the stock ecu.The turbo is a 60 trim stage 3 garrett t3/t4,the engine is stock nothing was done to the internals,stock coils and wires range 7 NGK iridiums.Went with the 44mm wastegate just in case we decide to use a bigger turbo.
Modified plenum in the making but for another single turbo setup this one is remaining as is.....here is a pic of the modified plenum for the next build.

Thank for the pic of the dyno run.

It makes power lower on the rev range than I would have thought, and holds it well. Very nice.
Is the graph definitely the at the wheels figure? Because if it is that would be really really nice.
Is the car running stock cams?
did you open the gap or close the gap on the plugs, i presume you colsed the gap up, what did you gap them to 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm?
I presume the blips in the power curve is the spark blow out you were talking about.
I presume the water methanol injection helped a lot to keep the knocking under control.
What fuel are you using, I presume petrol, and not E85, and what octane rating is the petrol if you are using petrol. I know in some countries you can only get 93 or 95 octane where as in the UK 98-99 is available.
So a setup like yours would run even better in the uk.

The dynos we have in trinidad can only read WHP Dave.Stock cams but plans are being made to install some regrinds from adam soon,
Car made that 380whp on 95 octane gas and water meth which helped a lot to keep knock under control.
Plug gap was reduced from 0.8mm to 0.6mm which cleared up the spark plug blowout.The aim was to make 400 WHP on a stock head/block,coils,wires etc.
Didn't expect to make that amount of HP due to the stock manifolds we used but i guess porting the outlet flange to 2'' helped alot....

just a short clip running on the dyno....

Raj, what you've achieved is great, it's just got that feeling of being too good to be true, I base this feeling on;

* Running it on 95 RON, I realise you have meth but... 95??
* Looking at the speedo in that dyno video, it looks like he's doing a run in 1st gear
* The video doesn't show the actual dyno readouts

Also, where was the IT sensor and what was its readout? I presume the temp on the sheet is the AT. Where the IT is placed could wildly skew the results.

If you have truly achieved this, I tip my hat to you

[SAF68]

Only 380 Awhp @ 20 psi with T3 turbo ?? You have a big problem Sir ....

Saf

[rajvr497]

Speedo is not working Jason that's malfunctioning.....lol
and yes 95 octane and water meth.
will be visiting the dyno again soon hoping to cross the 400whp mark will make a proper video this time showing the dyno results this time lolz......
