best engine for high power/weight ratio? AKA Ben's Cab

What Compression ratio is yours running at Highline, is it standard VR6?

 

Its 8.5-1 !

 

Is that standard?

 

Are all engine internals standard ! YES THEY ARE

So what it has a spacer plate it no big engine mod is it !

 

Post dyno plots or it didn't happen.

 

didnt think it would be long for tsc to pop in lmfao

 

b0ll0cks to dyno's you can cut and paste those from vortex....show us engine bay gyno shots!!

 

This banter is a little boring now, here are the facts.

You stated 750bhp was "Easy" to get from a VR6 Turbo....it is most certainly not "Easy".

Now the discussion point:-

Is a standard 1.8t a better base unit than a standard VR6 for a Turbocharged "Fast Road" motor....I have to say I dont know, theoretically there is no replacement for displacement so the VR6 motor should have more potential, however, the VR6 in 12v form only made 200bhp from standard whereas the 1.8t made 250bhp in standard form should be more robust, particularly in the top end where the exhaust valves should be a lot better suited to the temperatures associated with turbochargers, and the port design is very good in the 1.8t. I would guess at the pistons being better suited to high temperature applications aswell.

There is also the added bonus of not having to rebuild the base unit if you get hold of a low mileage one, infact Jabba's Ibiza in its first guize was a 100k miler with a big turbo bolted on and made 350bhp reliably....whereas the VR6 will always need to have the head removed for the spacer plate.

I dont know the answer but I would say for the same level of modification the 1.8t should generate almost as much power, is lighter, and packages better in most cars....that is until the budget gets silly, then the VR has more potential.

 

Without dyno plots, or 1/4 mile times, this debate is rather theoretical anyway. Fact is, a number of us do run our cars on the strip, and are happy enough to detail the engine specs alongside the times ran, or bhp figures. So HIGHLINE, over to you...scans with banana next to them please.

 

Will post a pic of my dyno results tomorrow with pics of my engine bay !
dyno results even have a run file with what boost it was running and that was after being on the dyno for over an hour when everything is red hot .
Had to stop runs at 1.3bar as plugleads where breaking down

0.6bar 325.6hp 438nm
0.8bar 339.3hp 425nm
1.2bar 387.4hp 495nm
1.3bar 407.4hp 553nm

will show graph tomorrow

If any of you where at GTI INTERS on the sunday you will of seen my car
smoking its tyres for the full quarter !

 

Do a search for Brian Kirchberger's Jetta , then go on youtube and search for vr6 turbo then tell every body you where wrong ok !

 

Out of curiousity, what times were you running at Inters?

 

It was the first time out in the car really and boost controller was not limiting boost .

I only did two runs first was a 1.2bar could not stop it spinning did a 14.8 and did my next run at 0.8bar but did not get a time !

 

1.8t engine is a much later design regardless of its heritage than the vr6 block.
no VR6 block turbo factory units that I am aware of, so whilst the vr6 may make more bhp for a turbo unit I would always choose the youngest design possible for a forced modified engine.

 

Heres what an almost stock engined vr6 can do

9.69 @ 145mph and 9.71 @ 146mph

All this with stock VR6 12v 2.8L engine, efficient turbo system, a good driver
and DTAfast P8PRO Engine Management

640 BHP at the wheels at 34 psi boost

Power train specs.

SP Turbo System consisting of :

SP Turbo Intake and Fuel Rail

Schimmel Performance Tuned DTA P8PRO Management

ATP/Garrett GT40 Turbo, ATP exhaust manifold SP Piping, SP 3" down pipe, Air to water intercooler.

Stock 12v VR6 engine
(50k miles with thicker head gasket, ARP head and rods bolts, hd valve springs)

Quaife 6 speed trans, Drive shaft Shop Stage 5 axels

- and don't forget, a skilled driver!

This car is over 700whp now BUT ITS NOT EASY TO GET 750bhp

 

I guess this is the search you are talking about....

"ATP turbo kit with C2 software. Brian Kirchburger is my neighbor and has put down 820hp to the wheels on a GT4202R, So did Steve Oliveira (yes, portuguese too)

For a daily driver i'd keep the boost pressure down around 10-12psi and run C2 software with a bigger MAF housing and 440cc injectors as well as a copper spacer. Then throw a T04E 60-1 and you got yourself a good 325-350whp."


I cant see anything on there saying easy....infact he actually reinforces the fact that it is far from easy by saying that he keeps it down to 10-12psi/325-350bhp, one would presume for reliability

I am not denying big numbers are POSSIBLE, they used to get over 1000bhp from 1.5litre(I think) Formula 1 engines in the early eighties....what I am disputing is your statement saying 750bhp is "EASY".

 

And what car do you drive ?

 

ok you are stating 640 hp at the wheels then over 700 wheel hp so which is it then

 

No thats not the search what car do you know that could do 820whp on 42lb injectors !
Stick to your jag engines
