This was discussed before. Did you read my post, last sentence?

Fair enough. I didn’t know some OEMs used them, albeit in niche applications. |

Now son, don't pull that card out. The majority of OE manufactures, both affordable and premium, use positive displacement units. How many people are driving around in a Koenigsegg? Let alone, driving it enough to know or care if it uses a centrifugal unit.

Back when I had no mid range torque I use to believe this too. Who wouldn't want to shift more and enjoy the peak of the powerband? Torque is for lazy drivers who just want to mash the pedal. There is a certain satisfaction to the way a centrifugal mimics the stock powerband without the torque dip. When I was looking for a SC kit the Edelbrock had just been released. I made sure to test drive both the 1320TVS and the Jackson kit. I recommend everyone take the time do this if possible! I was immediately enamored by the sounds and response of the Rotrex. The TVS on pump gas felt a little flat, with no extra sounds from the blower. My thought process back in 2015 was if I was going to spend the money on boost I wanted to feel and hear the boost. I was so use to driving the stock car for 2 years at that point that I was always keeping the revs above 4K rpm anyway and always had it on boil. Much like any mod you will get use to the extra power and I feel all the SC kits really need ethanol to come to life. If you are concerned with numbers or straight line acceleration and only have access to pump gas I'd definitley opt for a turbo. After having time to look back on the ownership experience of both kits. I think the Jackson wins in a few categories. It has the sound, it mimics the awesome character of the stock engine, it will put the least amount of stress (torque) on the factory internals. It still feels like a momentum car (sort of) which makes it so enjoyable to drive on tight 2nd and 3rd gear canyon roads. Which is what the car was designed for. But unlike the stock engine when you're slicing up a canyon and upshift to 3rd you are met with a delightful amount of power with the rotrex as opposed to an adequate amount of power in stock form. So although the Rotrex or NA wins in terms of canyon driving (my opinion) the TVS shines just about everywhere else unless your main concern is fuel economy which will be marginally lower. I do not have a dislike for centrifugals in general. I found it was well suited for my AP1 S2k and it made nice power from 4K rpm all the way to the 9K redline. They do serve a certain crowd and character of engine. In general I think if a car "needs boost" it is suffering from 1 of 3 problems A) the car is too heavy B) the engine is too small or C) Both A C38 car on ethanol with a 4.55 final drive is a very quick car even if it doesn't put up huge numbers to brag about. I found the shorter final drive to make the car even more fun in the canyons and more lively for daily driving. For AutoX the gearing became less than ideal and I wouldn't recommend it with boost. Going down to a 3.9 would probably be better. As much as I've preached how much better all the SC kits are with E85, at that point you are starting to push the limits on reliability. My recommendation is normally E85 and header for track guys and CARB legal SC for a street car. As much fun as it is to drive momentum cars and push them hard on the street; as I got older and started to do more track driving the less I started enjoying canyons. I still like them and am lucky enough to drive excellent empty roads daily but hardly ever push it past 5/10 's or 6/10's on public roads. It's just not safe or responsible even with only 200hp and prius tires. I'll take torque and lots of it in just about any other driving situation aside from the tight canyons. Everyday driving, freeway, autox, track, you name it I think it's more fun with ample torque. I find I shift way more on the street (not track) with gobs of torque. I'm constantly going up to 6th gear and back down to 3rd. I shift more with a V8 I think than I did with the Rotrex. The only difference being the downshift is optional. The car pulls great in every gear. So yes you can be lazy and not downshift but I don't find myself driving that way. To test this theory I'll be back in a momentum car this Friday at Buttonwillow. I have rented a 2300lbs, 135hp, track prepped, gen1 RX7 for the day. I will report back how it compares to a 2900lbs 500hp NA BRZ. Sorry for the long ramble, just thought I'd share my take having spent a decent amount of time with both kits. Last edited by GrabTheWheel; 05-19-2020 at 08:13 PM. |

I have a dirt driveway and use to do a little 1st gear slide in the dirt every time I came home. With the Jackson kit I felt like there was a little delay on throttle tip in compared to stock, it was much less noticeable after the retune but still there. I'd also think if you're doing a back to back comparison the louder car would "feel" faster. Not sure if they had similar exhaust setups? Although like I said I think the difference between a stock CARB SC'd car and a header E85 car isn't huge. |
