I am not sure if I understood correctly what you posted, but if you say that the stock VQ35 engine is good for 430-460 hp I must strongly disagree and ask you where you got that idea from? US forums...?

We can tell you first hand that you should not push it past 400 hp on a stock engine or you will have serious demage soon. We are talking German Autobahn conditions, not USA...! The real "weak spots" are the connecting rods in the VQ35 and the cooling in very first line.

The only supercharger kit that comes with a realy good out-of-the-box programming ist the STILLEN kit that we offer as only authorised dealer in Europe.

Installing a turbo kit (420++ hp) without modifing the engine internals etc pp will bring you back to the garage VERY SOON - so why not do it right the first time?

I am also talking about crank hp but if you are comfortable with what you are TOLD by the US guys... OK, it's your engine! We have build forced induction Z ourselves. It surely depends on the conditions but a car build for US highways or short quarter mile runs will not hold up to Autobahn conditions.

pour etre tranquil il faut tous ce qu as dit hotrider a une chose pres si vous voulez vraiment des grosses watts c forgé le moteur c pas donné mais qu en on fait laz prepa on es plus a 3000 euros pres!
Mais le plus chiant reste la carto c claire!!!

ba voila c pas parck on est en france que c impossible fo juste avoir les bons contacts(de confiance surtout!)
par contre hotrider au nivo des cartos que peuvent fournir les sociétés que tu as citer fo pas oublierqu au etats unis c pas le meme climat qu en france et ca y jou sur les prepas turbo maintenant sur l aspect mecanique si c bien fait c fiable c juste la carto ki peut tout péter!
ps: les videos ricaines des prepas avec turbo sont rarements forgées(bizar vu leurs budget) et ca donne deja pas mal alors une fois renforcé j vous laisse imaginnés la gouache!
le stroker jun viens surment du dernier streamz dans le dernier addx!? violent hein?!

[midnight pro-ject]

c pareil pour les prepas"supercharger" compresseur en french!lol
il existe chez stillen des poulies reduites qui procur une plus forte compression apres fo juste ajuster ce qu il fo!
perso j prefere vortech mais bon les gouts et les couleurs ca ne ce discute pas!

Yes, you can change the pulley to get more boost and power out of the STILLEN. We prefer the STILLEN (srew type, like used by Mercedes, Jaguar, etc) over the centrifugal types (ATI etc) because it makes more low end torque and it is much quieter, altough the ATI can produce more peak power. However, we believe the STILLEN matches the VQ35 engine characteristic much better:



This is the result on our own test car when it was completely stock and plus STILLEN. Notice the almost 1:1 shifted torque curve! 400Nm from 2000 rpm!

Meanwhile we have added a custom QAS true dual exhaust (2x63,5mm) and QAS metalic catalyzers (200 cpsi), stage 3 pulley, intake, oil cooler, ECU flash etc. We will soon head back to the dyno to see if we cracked the 400 hp!

There is a misunderstanding in the octane ratings of USA. They use an averaged value of "RON+MON/2" which indicates a lower number but in fact their "93" rated fuel equals our 98 RON!

I did not understand what you mean about 400hp impossible, can you please explain?

[Hotrider]

Here is an octane conversion table for your information:

RON= Europe
R+M/2 = USA

RON--MON--R+M/2
90.......83......86.6
92.......85......88.5
95.......87......91
96.......88......92
98.......90......94
100.....91.5...95.8
105.....95......100
110.....99......104.5

The whole secret is a good remap. You can even get 420 hp out of this engine but nobody knows for how long. Each engine , even if it's the same can be different and react different...like there are differences of 10 hp between two stock cars...
What kind of ecu's can you remap at QAS?
