I was just reading in the current "Excellence" (page 30 in Tech Notes, September issue) that starting in '99 C4 cars fitted with Bosch Motronic 7.2 received 300hp but I've never seen that documented anywhere else.

It basically states that starting with the '99 C4 they used E-Gas and Motronic 7.2 which in turned equated to 300hp.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

7 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

I was just reading in the current "Excellence" (page 30 in Tech Notes, September issue) that starting in '99 C4 cars fitted with Bosch Motronic 7.2 received 300hp but I've never seen that documented anywhere else. Has anyone else heard of this and is it true? Thanks, Nazz

POST 2Original post

I think the 99 comes stock with 296 HP doesn't it. 4HP increase is pretty small. Probably not worth the effort.

POST 3 / ORIGINAL POSTEROriginal post

I'm not suggesting an upgrade, I was just asking if what "Excellence" quoted was true. They claim that when the car when to E-Gas throttle control which increased the hp to 300hp. Can anyone confirm this? Thanks, Nazz

POST 4Original post

I got a gain of 11hp from a new cat back exhaust on my G35 and couldn't really tell. Sounds nice though. Dynos are so fickle. Maybe the day they tested the C4 that's what they got. I don't put much credence in any of these numbers. Just go by feel. That's what matters most right. How it feels to YOU. Well that's what I go by... The feel I really like is the feel of my C4s slick surface after a few coats of Rejex. HE HE

POST 6 / ORIGINAL POSTEROriginal post

That's what the article implies. It basically states that starting with the '99 C4 they used E-Gas and Motronic 7.2 which in turned equated to 300hp. Apparently that excluded the '99 Carrera 2.

POST 7Original post

e-gas was added in the begining of the 2000 MY to c-2 cars I think ALL c-4 cars regardless of year have e-gas.

This is a source reference. Confirm exact model applicability in the original material.
