A few tweeks later gives me +50 ft/lb

Upped the boost to 1.7Bar still with an Air temp of 72C

It's a completely different engine now.

Before:


After:

so what is the spec and what did you do to get the extra torque?

Good result

But why are your intake temps still high

Ben

Spec is:
Fully Balanced
Forged Rods
Forged Pistons
Very Light Headwork
Standard Cams
GT2871R 0.64
H&S Downpipe
3" System
630cc @ 3.8Bar
Walbro Fuel Pump
FMIC
SIP with RamAir
OMEX 710 ECU

To get the extra torque, I played with some settings on the boost controller, fixed a slight leak from the exhaust manifold and put a stronger dump valve on. My real problem is the high air temps which I cannot cure as I refuse to cut away my bumper or run water injection. There maybe some more top end power to chase if open up the head further or get some cams but for now I gonna stop fiddling and enjoy.

Jason, could,nt you just RRd your car with out your front bumper on to see the difference

Ben

Yes that will be my next test, I'm sure it will reduce the temps as very little of my intercooler is in the air stream but even if it does I'm not going to change anything as I want to enjoy my car for a while

72 degrees intake temps!!!!!! I would be very worried about det with them that high when the engine is pushed hard.

You are also going to be loosing a great deal of power - you want them to be in the 20's or early 30's.

It was 72C with an intake of 36C and still 72C with an intake of 25C. Det isn't a problem because when the temps rises the ECU pulls out timing and I loose power . I don't really want to run WI but I think I have no choice as I NOT going to cut away my bumper. Squid runs WI for safety (not mapped with the WI) and his temps have dropped to around 28C-36C in the summer.

I dont see the point in water injection, but dont want to open up a can of worms, as I'm sure that you know the pitfalls and drawbacks of using it.

at least you have the omex to pull back the timing - but it can only pull it back so much!

It's bumper hacking time!

I'm not sure on WI either.

Nice torque figure though J. Are you not slightly worried about the box? And when are you getting yourself back to the pod to get that 12 second run?

The temps will not rise that much that I will run out of timing to pull out, it’s also set to richen up AFR if it goes past a certain point. I am safe from det.

WI isn't that bad it you have an OMEX 710. It links to the ECU and you can setup parameters. For example I can set it so that the WI only activates when the air temps rises above 45C and a boost of 1Bar+ etc. If an error in the WI is detected e.g blockage or out of water it can switch to a different engine map. I'm not a fan of WI either but it’s looking like it might be the only solution for me. NO bumper hacking

I wasn’t going to post this up until the pod on the 1st of Nov but that day was a wash out so now I have to wait till March to set a time As for the box, if it breaks it breaks.

Charge cooler? http://www.pwr-performance.com/cooler.htm

Not a fan of them either. It would be better for me to relocate to Sweden

I tried to host these in my first post but they went out of sync, you have to download these mp4 to watch. If somebody could host these properly that would be great



Hosted on you tube see below, Cheers B

Hi Jason, interesting figures. What prompted you to go to TOTD again?

Do you fancy popping down to Perfect touch one Saturday to test the figures.

I'm not a great fan of WI, but it does drop the intake temps down by 6-7 degrees instantly, and that was with 100% water. Add 50% Methanol and it should be nearer 10 degrees and reduce chance of knocking.

Yes we should put ours back 2 back on the Dastek and see what that spits out. Anytime you like Squid.

Goods results and I love how aggressive the torque curve comes in, it's practically vertical

but you need to do something with the charge temps, maybe some inconspicuous mods to the bumper

it's hiding to true potential of your setup

Nice rsults Jason. Hopefully you'll unleash some more horses out of the engine after you sort/reduce the intake temperatures

What intercooler do you have?

I really think that you need to add water/methanol injection. It is the quickest and most effective way to reduce charge temps.

nice results jason. you do realy need to get them temps down but im sure you know what your doing. oh and by the way you've go the title wrong on youtube it says 347bhp when its 374bhp.

I losses power through transmission losses via you tube I didn't put the link up .

no such thing

why are dead against using water injection

you thought of making up an intercooler water spray system?or a cry02 system?

Can't use it as the pod or track days. Water injection is hassle and unreliable i'm not dead against it just not a fan.

Interesting that both yourself and Squid are making a lot more torque than most similar spec 20v turbos i.e. 40-50lbs/ft. Have you adjusted the inlet cam vernier? What about the cam variator, at what rpm have you set this to switch? You were running 1.7bar before, must be 2bar or more now?

Peak power at 5500rpm is very low for a 2871R too, the power nose dives at 6000rpm, sure you haven't put a turbo diesel in there

J haven't you got meth injection?

I could say the same about your recent string of cars being 30-50BHP more than the norm & over the compressor maps rated by Garrett. I prefer more torque as that’s the rpm range I drive in. How often do you drive above 5500?

I'm not sure as to why mine nose dives at 5500 rpm I should investigate it but at the moment I’m loving the torque and its getting even more stronger with the winter coming

I used to run 1.8Hold & 2Bar overboost with PT map but since I switched to the Omex and changed some of the engine spec I run 1.7Bar, Squid runs 2Bar. His BHP is 415 as it don't nose dive, guess the 0.86 helps up there.

I have a water injection system but the pump knackered over two years ago and haven't touched it since.

I just wondered if you had done anything mechanically to achieve this.

Not really I just built mine up to how I felt was best. What about you, have you done anything extra electronically to achieve your gains?

Lots

I'm at the opposite end of the scale, I quite like my power at the top end. When I'm driving normally I don't want a big thump of power. If I want to drive fast I shift down and drive accordingly.
