Administrators hughezee Posted December 24, 2018 Administrators Report Share Posted December 24, 2018 Maybe you would like your J30A1 engine to go a bit faster than it does right now. 😎 You will need the following performance parts: cold air intake system, a J37A throttle body, J30A4 pistons, a J32A2 head, a J32A2 intake and exhaust system. To make such a J30/J32 hybrid work properly, you have to configure the ECU, install headers and a 2.5″performance exhaust system. All these mods will increase the power to 270-280 HP, this is the optimum price-to-quality ratio. You can look for some performance cams, install high compression pistons, or do other upgrades, but it is not worth the money. You may avoid spending your money for what is described above and just purchase a supercharger kit that will give you about the same horsepower. If that’s not enough, then build a J30A/J32A hybrid and install a supercharger kit. This will definitely be enough. It makes no sense to go even higher, you will need forged internals, a turbo kit, and a lot of other components i.e transmission cooler or even a 6-speed swap. 2 Link to comment Share on other sites More sharing options...
Founding Member Retro Rich Posted December 24, 2018 Founding Member Report Share Posted December 24, 2018 I could be tempted now the V6 is no longer my daily driver. On the other hand, the power output is ample as it is. Would you increase Flex’s HP? 1 Link to comment Share on other sites More sharing options...

Unless I had a race track nearby then no point, but I even then I probably would buy the only manual swapped 3.2 in the UK which is currently for sale and give that a good thrashing as part of the weekly routine.😜 2 Link to comment Share on other sites More sharing options...
DeanoCoupe Posted December 26, 2018 Report Share Posted December 26, 2018 Lucky that as the US seems to really cater for the Coupe.... Comptech did the above supercharger kit that literally bolts on without supporting mods 2 Link to comment Share on other sites More sharing options...

Moderators PTR200S Posted December 26, 2018 Moderators Report Share Posted December 26, 2018 Looks pretty simple but although it punts the BHP up about 30 horses (15% ) the torque level remains the same at 264nm or 194ft lb ...... I would like a punch in the gut type torque at mid range rather than up top power..... wonder if the figures have been mis quoted. Might get my lad, in the States, to investigate some more... 3 Link to comment Share on other sites More sharing options...

I have fitted one of these superchargers way before starting the club and I wasn't impressed, think the owner went down the AEM engine management route to actually get some real power benefit. 1 Link to comment Share on other sites More sharing options...
Moderators PTR200S Posted December 26, 2018 Moderators Report Share Posted December 26, 2018 Was it as it appears to be in the spec then, not much improvement mid range? 2 Link to comment Share on other sites More sharing options...

When it was put on the dyno it made an extra 12-15bhp piss poor for the money spent my current coupe was better stock his was 1998 mine 2001 with different stock tuning setups anyway. so he went with a new ECU and was reasonably pleased, that's what I heard anyway? 2 Link to comment Share on other sites More sharing options...

Moderators Laird_Scooby Posted December 28, 2018 Moderators Report Share Posted December 28, 2018 A 70-80bhp increase from bolting on a supercharger? That's 35-40% in one hit. Not many other bolt on goodies can give that sort of instant power hike with no other mods! 1 Link to comment Share on other sites More sharing options...

Sorry for the delay haven't found any realistic prices yet and there are some additional costs to consider, the battery will need moving to the boot, the transmission will need a cooler, new radiator due to age etc etc 1 Link to comment Share on other sites More sharing options...
Moderators Laird_Scooby Posted December 28, 2018 Moderators Report Share Posted December 28, 2018 Not to be ignored though is the fact that the supercharger itself is parasitic so probably eats about another 30-40bhp of the increased engine output, with a similar amount of torque being swallowed in addition. Out of interest, what is the basic power figure for the USA-spec V6 model? Link to comment Share on other sites More sharing options...

I know a supercharger is parasitic, but 30-40 bhp loss on a 200bhp engine pushing 280bhp does seem a little excessive but im no expert. Saying that the blower on the Mercedes SLR needs 150bhp to run it..... 1 Link to comment Share on other sites More sharing options...

Can't transfer it on this device ,Dave , sorry ! It only gives another 30bhp on top of the 200bhp standard motor but worse still is the fact there is no torque increase to be had, hence the comments. 😶 1 Link to comment Share on other sites More sharing options...

But supercharger whine is so cool 😎 Joyful tunes !! I had a Honda VFR 750 and a 400 version that were cam drive rather than belt or chain. The 400 had an addictive whine just like a supercharger and as a consequence drank fuel like the 750.,....... I was always running it up through the rev range 😄 Mate of mine has a V8 supercharged Jag ( well, a Daimler, actually, don't you know ! ) and that is a beautiful sound on cam going for it !!!! 1 Link to comment Share on other sites More sharing options...
Moderators PTR200S Posted December 29, 2018 Moderators Report Share Posted December 29, 2018 Apparently there is a rotrex system for the US Accord V6 but it loses the airconn. The comptech system doesn't seem to have much going for it according to the US boys...more investigating needed. 1 Link to comment Share on other sites More sharing options...

Even taking that into account, a 30bhp gain isn't a lot especially for the cost involved. 1 Link to comment Share on other sites More sharing options...
