We're nearing the physical completion of our turbo kit for the E90. The car will be driveable this Wednesday. The turbo kit required a lot of special fabrication which will make the end result very very nice. However, it took a lot of work and ingenuity to pull it off.

My requirements for this particular turbo kit are:
1) No cutting or welding on existing components so that the car can be returned to stock if necessary.
2) Complete bolt on with no tuning necessary.
3) No check engine lights period!
4) Safe and reliable.
5) All hot parts must be heat shieded or ceramic coated.

We only had to violate #1 in one particular location. The car has a unique front air duct that also holds the radiator in place. There were two options, one, make a cutout in this air duct to provide perfect fitment for the intercooler or use a water/air intercooler. Water/air intercoolers have the unique problem that if they fail, they can hydro-lock a motor. That violates rule 4. So this kit will have an option that includes a new complete front air duct with the hole already cut out of it not violating any of my initial rules.

Here's a sneak peak at the front of the 330i nearly ready to roll. Here's a video of the kit in pre-production testing. www.horsepowerfreaks.com/videos/330iTurboKit.wmv

Take care,

put the tag around the image url

and id say throw this in the FI forum, more people will see it there

You don't have enough posts to post pics. . . .If you want I can host em for you . . .

what numbers are you guys hoping for?

Chris,

Please email advertise@bimmerforums.com to get signed up to become a supporting vendor or else we will have to ask that you not continue to market you products to our audience as it is unfair to our other vendors who contribute to help make this site what it is...

now what kind of numbers?

saw your post on e90post! can't wait to see the finished product!

quite interested...

saw your post on e90post! can't wait to see the finished product!

Thanks. I'll have some video of the car in action later this week. I'll post it up here.

Take care,
Chris.

You guys make stuff for the Mazda Proteges also right ?
im and ex-MSP owner

I just drove my turbo'd 330i about 20 miles today. It drives awesome. I didn't get into much boost but I sure wanted to. Here's a video of the completed kit installed along with my exciting narrative. :)

Here you go. http://www.horsepowerfreaks.com/videos/330iTurboKit.wmv

holy crap!
got any dyno numbers?
B

def wanna see more....as in HEAR it rip and see it on a dyno...gt32, dont think you are gonna blow anything?

all i can say is "damn".

HPF is a well known and respected company in the supra community

Now if only you guys would make a E46 M3 turbo kit!

Thanks guys.

We are expecting approximately 100hp increase over stock on the 330i.

Speaking of the E46 M3, We will have the E46 turbo kit completed shortly and plan to debut it at Bimmerfest in California. The electronics and tuning will be done by Technik.

So I'll have video of the E46 turbo kit as well in about one month.

Take care,
Chris.

sounds good def will be waitin for this...

2) Complete bolt on with no tuning necessary.
3) No check engine lights period!
4) Safe and reliable.

I think you have a lot to learn about proper operation of the torque-based ETC strategy if you plan to meet these goals. C'mon over the the forced induction forum here and start a new thread where this kit can be discussed better...

Eww...he called it a beamer :P

howabout an e30 325 kit? :D yeah not gunna hapen :P

Awesome news!

i tried giving them a call to check out the setup. They seemed very tight lip about it. I dont blame them to be the 1st in the market to produce this kit for the E90.

If you have any questions you can private message me, I'll be happy to answer them. Most of my staff isn't privy to the contents and specifications of this kit, so if you call ask them to transfer you to me and I'll be glad to answer any questions you might have.

Take care,
Chris.

Making WOT power using a standalone ECU is literally childs' play compared to performing proper calibration of BMW's torque-based E-GAS strategy. I'd love to see the source for the software if he has legitimate control of the ETC safety strategy in the DME. Any proper street calibration should have something other just a trick to disable the safety checks if they don't wantto risk being sued for negligence if a car has a "runaway condition" at part throttle. Like I said, WOT is e_a_s_y.

any idea of how much?

Anymore on this?

We ran the E90 yesterday up to 8psi. The turbo definitely makes boost and it comes on fast. We are in the final developmental phases right now and there are a few more things we are working on to complete this project. We're hoping to have the car completely dialed in before Bimmerfest.

In regard to pricing... I'm hoping to release it with a price tag of $8900 and begin selling the kits in May. You can always email me at chris@horsepowerfreaks.com if you have any comments or suggestions and I will continue to report the progress on this thread.

Take care,
Chris.

Would this turbo kit fit in an E60 as well since they use the same engine?

The E60 was going to be the next turbo kit we were going to develop, which is why I bought one of those cars. However, the demand for the E46 turbo kit was so strong that we decided to put the E46 in front of the E60.

Now I'm not sure if I'm going to make the 325 kit next or the 530 because there's considerable demand for the 325 kit. Any thoughts?

Chris.

Seeing as I own a 530, I'd vote for the 530 next... I just thought that since its the same engine it'd be relatively easy to adapt it to the 530.

Id say you'd probably have more sales success with a 325 kit.

I think the 325 kit would be a better bet, and wouldn't be a whole lot of work either.

Looks great:thumbup: do you have a kit that will fit the 325i or will this one also fit the car?

S

I'm thinking of doing the 325i next since it is so close to the 330i that we just finished. If there's anyone that wants to donate their car for the 325i development, let me know. I don't really feel like buying another new car, and you'll get the kit for our cost plus free installation.

We've made considerable progress on our E90 in the past few weeks and are nearing the end of our tuning process. Flawless driveability, absolutely smooth transition of power, and the car just keeps on pulling. We've been gradually turning up the boost and are now at 6.5psi. We're going to turn the boost up a bit more tomorrow and take some vids. Shortly we will strap it down to the dyno and see what it puts out. It is definitely a LOT faster than it was. I'll keep you all posted.

Take care,
Chris.

Awesome update. Care to share what your using for software/fuel management?

E90 Turbo Kit Release Delayed (with no eta)

Tuning the E90 has been more difficult than expected. The computer immediately overrides any changes we make to the A:F mixture under boost. The computer in this vehicle is always in closed loop and always monitoring the A:F via several factory wide-bands. Any changes made to the factory fuel pressure are compensated for by the ECU. The stock fuel pressure is 70psi. We've gone so far as to increase it to 120psi which takes the computer only 1 second to drop the injector duty cycle to compensate for the increased fuel pressure. It is quite amazing, however, it makes it so we cannot get the A:F ratio down to a safe 11:1 under boost. It will go there for a brief second, then will rise back up to 14:1. In a few cases the car has stayed at 11:1 up to around 8psi of boost and it pulled very hard. However, it appears that once the car gets warmed up, it tries to compensate for this fuel pressure increase.

Samir from Technik will be tuning our M3 E46 turbo kit (shown in the picture below) shortly, and we hope that over time he will be able to crack the E90 ECU, so we can sell the E90 turbo kit. If anyone has any ideas to help us, we'd be happy to hear them.

Here is a teaser pick of our M3 turbo kit which will be released shortly.

Take care,
Chris.

I'd try contacting Nick G. at Technique Tuning or Jim Conforti @ Eurosport High Performance. They are the only 2 indviduals who have the knowledge(in my opinion) to remap the E90 ECU.

i'll donate my 325ci for the turbo install, whoops i guess only for e90s
