Thanks for the response btw, very lengthy and adds more insight to those that are curious on this upgrade. I don’t think the price is crazy or anything, and the quality of the turbo is definitely there. Not for one second do I doubt Chinese production quality in recent years, I think the negative stigma surrounding Chinese produced products is definitely over-exaggerated. Their production quality and quality control is definitely impressive as of late. The support from IPOS can be better but no business and brand are 10/10, there are definitely shortcomings. I’m just here to try and provide a unbiased review. I’ve said what needed to be said based on my experience with my purchase, and that’s all there is to it. |

Let me address your comments when it comes to my car. There is some debate around when you go with a bigger turbo, if the electric motor actually adds anything. Most well-known tuners I have communicated with believe the electric motor is mainly used at lower rpm ranges, once you go with a bigger turbo and start pushing, they think it adds actual load. Please stop making up numbers about my car, there are videos online which shows exactly what it made with the BBT and nitrous as well as a stock baseline. A 125hp shot of nitrous dyno was never showed. I did 499whp with BBT on e40 mix with around 30psi boost (NO NITROUS). This was without PI. The turbo is rated by BBT to flow 50 lbs/min. This is pretty much aligned with what BBT made on his regular b48 non-hybrid with ethanol. Which shows that the Electric Motor does not add anything. When I added a 50hp wet shot of nitrous, the car made 561whp as it was limited on fuel. With additional fuel (PI), this turbo can make around 34psi. At 20psi on very low grade fuel 91 octane, this turbo makes 390whp on a 330e. Another factor, look at the BBT size. Its equivalent to a g25-550 similar to IM450 but slightly bigger. The AR housing and manifold is larger, hence should have less restrictions. IM450 I believe did 470-480whp on a B48TU engine (a more efficient engine). BBT is laggier as it’s a single scroll design. BBT is much more complex and requires modifications to install as you can see from my videos online. Here is another piece of data for you which shows the electric motor adds nothing: LCP did 505whp with their China version of IM500 without PI and around same ethanol content I did with BBT on 330e hybrid at 499whp. Both aligned to maxing out the DI system at around same power level. Turbo kit prices: BBT 600 kit - $3650 (I actually paid $3,054.10 a couple years ago for my kit which was on a sale which came with the BOV) IM500 - $3150+ depending on options IM450 - $2650+ depending on options. China IM500 - $1600 you can get the same sized IM500 turbo which is manufactured in China g25-660 sized. The LCP guys from China just made 505whp on this turbo. The smaller IM450 (G25-550) is slightly lower priced. These hybrid turbos have been out for quite some time. The smaller hybrid turbos spool faster. With stock turbo, stock engine low grade pump gas and meth, I did 100-200 time of 10.98s and 1/4mile time of 12.83s (full weight with methanol kit). With BBT e40, I did a 100-200 time of 8.04s and a 1/4mile time of 11.91s with full weight+ (nitrous kit, meth kit, did some custom work in trunk for fitment which adds some weight). NOTE: I NEVER timed the car using nitrous. I have seen another 330e with IM450 doing 100-200 time of 9.65s and a 1/4mile time of 12.71s. I have no other data on what boost but heard it makes around 350+whp. Currently my car is on a top mount turbo kit that I developed and it makes 550whp hitting some new limitations even with PI - this is with only boost & fuel adjustments, no timing, no valve timing, not a completed tune. Could have made more but already planned to upgrade the other component. Based on the rating of the turbo and how much it makes on 6 cylinders, this contributes to the electric motor not adding any power on top and possibly creating additional load. Everyone is unique, trying new things, sharing information, helping out each other is what makes a great community. Last edited by SRHosein; 12-07-2023 at 05:20 AM.. |

it's just make me went insane how could a custom tune run way much slower and more "conservative" and much worse than an ots map when my log on ots map both on 98 and e30 simply just ran perfect without any slight of timing correction , throttle closure ,knock , etc how could other tuner that he called "do not care about 4cyl bmw" simply tune much better than him? here's some dyno numbers to throw note: this is a crank measured dyno based on my own car: stock tune:200hp/290nm (320i , fbo) 98 ots bm3 stg2 : 290hp / 400nm E30 ots bm3 stg2 : 330hp / 440nm navardi tuned 98 : 270hp / 360nm (lol , not only the number is very bad the driving experience was very shit as well , the fact that i need 50% of throttle input just to keep up with 60mph highway is ridiculous , car felt slugish AF even stock tune felt much more responsive than his tune , you realy need to wot in order to realese that shitty 270hp lmaooo) e30 navardi tuned: idk i just gave up midway LMAO , we had 10 revision without any improvement and as OP said and experienced , i dont want to blow up my engine by doin way too much pull with a very shit tune without any improvement from the previous revison it seems that he got confused by software limitation or other things but he refuse to acknowledge his confusion other tuner custom tune on 98 : 320hp / 445nm (5 revisions) other tuner custom tune on E50 350hp/490nm ( 6 revisions) the closest n20's power on this dyno in my country is like 340 hp / 470nm i know that every dyno is difference and measuring numbers in a different way but all of this ran was done on the exact same dyno so be careful out there i believe some might have a good experience with navardi but for me it's always been terrible for both 98 / E mix tuned big shout out to harry/navardi to create this bmw wiki but i hope they can make their customers service better as i need to wait almost 1 week betwen revision ,tuning wise idk , maybe i just have a bad luck with him again i don't want to bash him as others might have a very nice experience with him this is just my personal experience the rest is up to readers to decide |

I have also had issues with Navardi tuned and IPOS motorsports. their Attitude is terrible and part quality is shit. They have trouble accepting that they made a mistake and rather defer the blame on you.
I have a thread in the n20 forum about it and they make every excuse in the world rather than just making it right. Then he has his influencers posting trying to also defend him saying nonsense. |

Curious If you can run im450 with the stock tune to complete drive cycle to pass the smog test. I'm living in Cali hellhole. Cannot escape the eventual smog test. I'm not quite worried about the visual inspection as the im450 looks pretty stock and will be mounted deep in the engine bay. The only concern would be the ecu tune test.

Hello
My name is Didier, I live in France, I ordered an IM450 at the end delivery date is February and the deadline is the end of April but I also placed orders with other suppliers (valve kit and ATI pulley) that I had delivered to him to have a single shipment... For the moment I have to say that communication is rather complicated, the delay to our email exchanges is very long... Last edited by minicooper31; 04-04-2024 at 07:30 AM.. |

Hello
Thanks for your message, I've received all the parts for the cylinder head, bought directly from Supertech, as well as the ATI pulley, the turbo is missing. The 200 cell catalytic converter is really nice, I can't wait The engine is waiting patiently, I'll give you the power bench and hope that we'll be able to exceed 390 hp. |

If yes, then you would want to upgrade to M340i HPFP, would help the tuning aspect drastically. OEM injectors are good. Which model and year do you own? |

Hello
Thank you for your answers I will buy the pump . The project is quite important because apart from the motor the outside part will also accommodate a complete jcw kit from 2021. Concerning the chassis, it is entirely made of powerflex. There's a large-section stabilizer bar (25mm and 27mm) and a bilstein pss16 kit. The tires are semi-slick. Braking will also be reviewed. a bigger master cylinder, aviation hoses and, above all, grooved discs, Hawks rear pads and ferrodo circuit front pads. We've installed the differential. The line will be a 3" and the catalytic converter will be a 200-cell (the one pictured). We will also install a pulley for the ATI crankshaft. I hope the power will be over 390 hp. I'll take pictures of the cylinder head. I'm happy to share with you. In France, there is little preparation because the laws are quite strict. Last edited by minicooper31; 04-23-2024 at 11:09 PM.. |
