big power vr4

[kevin ap motors]

The car is almost there spent over 30 hours the weekend putting it all back togather looking realy good.
Having to change the a\c fan to slimm line as std is rubbing on new manafolds.
Had bid probs getting engine back in due to new manafolds and turbo set up
Droped car to exhaust shop to have downpipes,intakepipes and intercooler pipes made up today should be ready tomorrow pm .
Then i can put on the kad set up for the front and sort out the rest of the wiring then time to start the beast up :inquisiti :inquisiti
hopfully all will go well
Will let you know the outcome
I think spirit might pop down to hear it running:evilgrin:

[Spirit]

Good to hear some positive progess after Friday mate :2thumbsup

You can be sure I will be popping down.........very soon :evilgrin:

[bradc]

Great news. When will the pictures and dyno sheets be up?

[Paul Beazer]

Oooh cool, be interested to find out what its putting out.

[BraindG]

GJ Kev!.. can't wait for this one! :iloveyou:

[Dan_G]

brilliant!... hoping for great things... :2thumbsup

[The Vee]

Great to hear its nearly there. :2thumbsup

[Spirit]

Will try and get down later today, oh and bring the cam if I remember :2thumbsup

[Kalle]

How is it going?

[BraindG]

/Hyper /Hyper /Hyper /Hyper

Ohoooohohoho,, do tell :beerbang:

[Nutter_John]

I sure I read a post from Spirit where he aluded to the fact he'd done 120 in third gear <- wtf is fifth going to be able to do ?

Need more info Kev :D

[Louis]

I can get to 90 ish in third, at about 7k revs, surely you must be doing over 8k revs to be at 120mph??which is cool, ( I am hoping to hear that with the mods you can rev up to ? with out damage)

[Spirit]

I have since been reliable informed that the VR4 box cannot do 120mph in 3rd, so maybe Kev can enlighten us ?

[White Lightning]

I was just thinking that couldn't be possible. If 90mph is 7000rpm then 120mph would have been around 9300rpm :thinking:

[Wodjno]

This is true ! But has the Gearing been changed ?

[Nutter_John]

From the video's the gearbox did look very very new - EVOone ?

[Wodjno]

What Video ??:speechles

[Nutter_John]

spirit posted 2 videos off the car running and being set up

[Spirit]

As far as I know its a standard VR4 manual box

[Wodjno]

As far as I know its a standard VR4 manual box

Then the only way that speed is possible :inquisiti Is if te Ehngine has been extremely well balanced and other parts lightened (eg.. Fly wheel etc)

[Spirit]

Well it will be a lightened flywheel, and the engine is definately well balanced.....guess it's time I made a visit to AP and gather more info

[Nutter_John]

need more info -= NEED MORE INFO

please Pete give us more info /lol

[Nick Mann]

I agree - 120 in third means altered gear ratios or a very high rev limit.

Either way, I am looking forward to an update - this has to be the most interesting project in the UK at the moment!

[zentac]

I sure I read a post from Spirit where he aluded to the fact he'd done 120 in third gear <- wtf is fifth going to be able to do ?

Need more info Kev :D

hehehe... on a manual box with standard ratios the car would have to be hitting 10,000rpm to get a speed of 120.848 MPH

[White Lightning]

And this one still has the tiptronic doesn't it Pete?

[SGHOM]

And this one still has the tiptronic doesn't it Pete?

nope !! converted to a silly gearbox. /Elmo :undecided

[Spirit]

Correctomundo sir :evilgrin:

[ciderisgr8]

I was down at AP on Friday and Kev had his motor on the dyno.
The first run had him with 360 bhp at about 5000 rpm, with still abit of mapping to go then it would be interesting to hear what its pushing out now.
Sounded sweet when it was running on the rollers.
Good luck Kev

i presume that was at the flywheel

[bradc]

It had better be at the wheels! 360hp at the flywheel would only be about 200kw at the wheels, Uc's car has that much and he is still on stock internals and turbos.

[richy rich]

yes but changing the internals and flywheel don't add power but with this done you can start increasing as you wish, i don't now if he is doing it gradually or going all out.

[bradc]

Upgraded turbos should push it way past 200kw at the wheels though.

[valmes]

360 hp at what boost? Does anybody have pictures of his setup? What turbos did he finally settled on?

[Spirit]

Spoke to Kev briefly earlier. The 360hp was with standard injectors so that's what is restricting him, plus only 0.9 boost (and he thinks he can get 1.9 boost) and still got a lot of mapping to go.

He is still confiident of a figure around 600hp once complete.

i thought he would do it like that.

a little at a time

[scoobyDAZZA]

shame he don't know how to drive


i've tried teaching him but he keeps shutting his eyes pmsl

[bradc]

Seems strange to me he built it up with the stock injectors. What size is he going to go for?

[Spirit]

Not if you knew the money that's been ploughed into this. Maybe he decided he could run it in with standards, then save some more cash to pay for injectors/mapping etc once it was all up and running.

[bradc]

Dunno, I've just spent 10k on mine, and almost everything needed for turbos has been, other than the injectors, manifolds, downpipes and the turbos themselves.

If I was upgrading my turbos, the first thing I would do would be to remove the stock ecu and MAF and change the injectors, so it seems strange he has done it this way.

[Spirit]

The stock ecu has been replaced, the maf is gone, and I assume the injectors will be ordered soon.

[bradc]

Right I get it now, I remember he had it running on the stock ecu at one point as well.

So he has done the turbos and internals, then slowly adding things to it like the ecu, injectors, etc to check it all as he goes along. That makes more sense. :)

as ive been saying brad

[zentac]

So what ECU is he running.

[Spirit]

So what ECU is he running.

Map ECU I think

[zentac]

Map ECU I think

Cant believe hes using a MAP ECU, that doesnt give you any ignition options, just fueling.... going to all the work he has he would want to be able to advance the timing.

[Eurospec]

Timing control is certainly something very useful to have. The more control, the better in my book.

A Map ECU is a very good piggy back controller, ( i would say that, because we sell them, but i really believe in it) but that is what it is. ECU's are horses for courses and whether or not you NEED timing adjust depends surely on what you intend for the car.

I just ran an 11.7 1/4 mile at 21psi of boost with no timing adjust and no knock. And that was in my 1.8 tonne tank!

Its a common beliefe that many mitsu engines 'love timing' by which people mean they respond well to ign advance. In my experiance this is true to a point, but when running bigger injectors on a piggyback with the std ecu in place the reduction applied to the airflow signal will trick the ecu into believing the engine is under lighter load than it is. This will cause the std ecu to select more aggresive timing, effectively giving you advance through the back door.

In the turbo applications though, you might not want that because if you are using big injectors and high boost on our lovely 98 or 99 ron fuel you may end up with too much advance through the back door and so run in to knock. If that happens you would need to increase octane or retard timing.

Cheers,

Ben.

I've got an Ultimate if he changes his mind ;)

[bradc]

I'll keep my autronic thanks!

[zentac]

I'll keep my autronic thanks!

If you ever get it ;)

[bradc]

Well technically the ECU is in the car, I just don't have the car. :)
