Nice going Gunni, and your ex head is perfect on my block.

[ImysE30]

Think i've seen this about

Looking very good, awesome work

[Gunni]

450cc´s at 50% duty@5k and it´s only 0,45bar boost

They will probably max out at about 1-1.1bar.

Drove it around today to do some fuel mapping, it´s spot on now, just need to get "out" where I can really try some higher boost.

EDIT.
Overall this 8.0:1 compression ratio 2.8 is sucking in on average 17% more air then a 2.5 does at same KPA and RPM. So this cheap stroker conversion is well worth it.
No such thing as bad throttle response either

[stembo21]

how much has all this cost you? look ace by the way

[cool_ram_in]

Great work Gunni!

It must be amazing the turbo engine!

Is there any lag on the throttle?

By the way, i love the zinnobar color and the black wheels...

Really spicy!

[Gunni]

how much has all this cost you? look ace by the way

Who knows


There is no lag, but I´ll have more info on the boost threshold(when it comes in rpm wise)

[march109]

Cars like this have me coming back to the zone!

[Gunni]

This is the engine idling.

[stembo21]

well done was the wireing hard to do? am thinking about doing a turbo on a 325

[Gunni]

I´m a fuel injection installation specialist, so no

[stembo21]

o ok lol so if i got all the hard work like puttine the turbo on exhust ect. how much would you charge to do my wireing ?

[Gunni]

Depends on where you live

Here is my "channel"

[Gunni]

Got a tax disc today, so everything is sorted.
took it out, it´s maxed now

450cc´s are at 90% duty at just 1.1bar.
We´ll see what that is on the dyno next week.

It´s a damn monster btw.

[GrindCulture]

Any chance of some "in motion" videos? top work

[Gunni]

there will be very soon

[ImysE30]

Get it debadged

Sounds foooking awesome

Look forward to seeing this tearing up the streets of Derby

[toby]

Any chance of some "in motion" videos? top work

+1

[oakey]

Awesome stuff!!
Santapod Gunni???

[Gunni]

That would be so useless

it´s only got 215/40-16´s and an open diff.
traction is just not there.

My friend works at race technology and he got a video datalogging thing we are going to use today for some video/kmh/rpm/g recording.,

[Gunni]

Here are a couple of vids with the ignition not even tuned yet.

[ImysE30]

Awesome
Where did you do those kind of speeds?

[stembo21]

you have done a good job that is fast lol cant wait to do mine

[e30bmlover]

man thats @ucking fast! good work there!!

[m_jermyn]

show off

[Gunni]

Well I didn´t quite get 400LBS torque like I had hoped, but

466LBS !!! ,, This is SO crazy now.

I took the car to Sal at Evolve and had a bit of fun tuning
This is where the car was before tuning



And this is same boost but after tuning.



3rd gear looses traction now after I tuned the ignition.
And driving this is INSANE!!..


Having a car tuned on a dyno really makes a difference.

[ImysE30]

INSANEEEEE but so

Do you give test drives

[gcs325i]

WOW well done with those figures, must be a fun drive.

[E30BeemerLad]

Missile!

Very impressive

[Simon13]

That is really really impressive, sounds like you have surprised yourself!

[Jhonno]

Jesus that is quick!!

Nice work Gunni

[Bavarian_Autotech]

Awesome
Where did you do those kind of speeds?

on a rolling road

[Gunni]

On an airfield of course.

[Ant]

Nice Gunni NICE dude

I've gotta bring the Gadjit M20B27T to Sal in the next week or so, maybe we can hook up and do back to backs ??
