cadguy77 0 Posted April 10, 2008 Report Share Posted April 10, 2008 great job on the setup, hats off.How do you find the power delivery from the rotrex? is it smooth like the vortech, or does the power kick in alot later? Link to post Share on other sites
VWC 0 Posted April 10, 2008 Author Report Share Posted April 10, 2008 Kalv - yeah pop down bro anytimeSetup does cost some £££ but then not as much for the power i got, started with the engine/transmission around 2 years back and built it up from thereThe schimmel intake/cooler/cams make a big difference but with the vortech even though it got 337hp with 12.5psi it then struggled to boost above 10psi with belt slip and it had limits... the difference in torque is 260vs330 so the rotrex is lethal and delivers alot stronger throughout the rev range...but its the whole setup which i dont think anyone else has thats got the results in the end - I will get a spec list up soon Link to post Share on other sites
Matt W 4 Posted April 10, 2008 Report Share Posted April 10, 2008 Thats just awesome, must be a real wolf in sheeps clothing when out and about! How does the car handle the power can you put all of it down or does the car struggle occasionally? Link to post Share on other sites
VWC 0 Posted April 11, 2008 Author Report Share Posted April 11, 2008 Is that the highest boost pully?its a 85mm pulley but you can go higher someone had over 20psi on the rotrex here beforeThats just awesome' date=' must be a real wolf in sheeps clothing when out and about! How does the car handle the power can you put all of it down or does the car struggle occasionally?[/quote']Its not too bad the peloquin diff helps a little and its not like a sudden lump of torque like a turbo, so you can have fun but with some control too Link to post Share on other sites
VWC 0 Posted April 12, 2008 Author Report Share Posted April 12, 2008 Dyno Plots below – torque is a lot better nowBHP: 402.4@6676rpm (Hot Run)Torque: 330.5@5960rpmPulls hard through all gears… from 2k it starts to boost, by 5.5k I’m seeing 10psi… that’s pretty good for a charger… but after 5k it goes mental I cant even look at the boost gauge just hold on and keep eyes on the road…revs up to 7250rpmYeah 400 hp is a lot but its not about that number it just delivers the power so it can be controlled as theres no torque spike just balanced Link to post Share on other sites
Radostormvr6 2 Posted April 13, 2008 Report Share Posted April 13, 2008 Nice dyno plots bobby, Your rite about the schimmel parts, they all work well together . There not cheap but well worth it. Link to post Share on other sites

[/quote']cheers shaun that run was after the car had been running for 40mins of mapping, the chargecooler is quality with the intake, the cams did the job 2 picked up an extra 23hp & 25lb-ft... but the rotrex is lethal no belt slip and rips through from 5psi to 15psi+ no problem Link to post Share on other sites
Radostormvr6 2 Posted April 14, 2008 Report Share Posted April 14, 2008 Great work mate, 400bhp must be mad. I will be there soon Think it will be the long turbo road. Link to post Share on other sites

Phat VR6 3 Posted April 21, 2008 Report Share Posted April 21, 2008 Looks nice in there. Ive always wondered what they look like lol.Can you spin the charger upside down if you where using a front mounted intercooler? Keep the pipe work shourt. Or is it fixed like that Link to post Share on other sites

VWC 0 Posted February 19, 2009 Author Report Share Posted February 19, 2009 Update.Needed to sort a few things like tired valve springs (7500 limiter), better exhaust and dodgy alternator but ended up doing all this…Slowly did all the work over the last few months myself as there was no rush and saved some cashIt’s now back up and running checked everything over and its all good so happy I gave it a go Link to post Share on other sites

supersix 0 Posted February 20, 2009 Report Share Posted February 20, 2009 Hi mate, Cars looking sleek dude!I have the c30-94 stage 2 on mine with almost identical mods but i have the standard inlet manifold for the 24v, how come you have chosen to go with a short runner? I have one in the garage but was warned i could loose torque? Link to post Share on other sites

john555 0 Posted June 15, 2009 Report Share Posted June 15, 2009 thats cany impressive im only looking at around 300 with my v9 almost maxed out think i mite go for one of them my comp is alredy 9:1 off a spacer plate so would be rude not to what sort of power would you expect with a 70mm pully?cheer john Link to post Share on other sites
