Honda CRX track car build (270bhp N/A)
Discussion
I had a non-VTEC CRX in the same shade of pinky-red - used it as a daily for a short time then took it sprinting at Curborough - won my only sprinting trophy with it!
It was fairly handy with 138bhp, so your must be properly mental with double the power - it must be a hoot to drive it hard, although I suspect it won't be much good as a daily driver....

Cant wait to see this thing sing on track.
Ben you using the EP3 plate at all?
I'd love to, but it's an E-reg car, so I can't put an R-plate on it Ben you using the EP3 plate at all?

You're absolutely right, it's far too harsh. Even hitting a catseye is a major event. Like hitting a deep pothole in a normal car. It's brutal. Far too loud as well, much more than expected!It was fairly handy with 138bhp, so your must be properly mental with double the power - it must be a hoot to drive it hard, although I suspect it won't be much good as a daily driver....
It's all progress now chaps! I've done about 50 road miles in it without much issue.
I have a second set of wheels, Team Dynamics Pro Race 3's, which I intend to use as dry track tyres. I bought 2x 225/50/15's AR1's and fitted them to a pair of these wheels. I've read nothing but praise for these tyres.
They were too wide for the rear, sadly, but that's what I needed to know to move forward.
They went nicely on the front. The rears are now some scrubbed AR1's in 195/50/15
I've also started replacing the terrible 80's bulbs for LED ones. Here's the dipped beams sorted. The rest are on order.
In my first round of road testing I also did a quick decibel check... Oh dear!
That's going to need another exhaust box fitting.
Next up:
- 150 mile roadtrip in it
- More uprated bulbs
- GoPro mounting
- 2x Cadwell trips
- Santa Pod

I made the trip once more to MIJ exhausts, who'd seen pictures of the system they made and told me it could be made quieter with an additional box. Arriving at MIJ they told me they couldn't fit any more boxes in! Total waste of time!
In frustration I headed home, then on to Cadwell for a professional noise test, to end all doubt on the system one way or another.
Cadwell says NO
116db is beyond any regular UK track day.
I'm going to have to drop down to 2.5" exhaust and lose power

Before you do it has to be worth getting a second opinion on the boxes.
There must be another exhaust expert who can change your boxes to reduce the decibel level.
Hopefully someone on here will be along to advise.
I hope so mate.There must be another exhaust expert who can change your boxes to reduce the decibel level.

I've just ordered a 3" exhaust from Solid Fabrications, they do a 'super silent' system, how 'silent' it is I am yet to find out but worth an enquiry to see if they can help you?
If that's for an EP3 I had the same system, it's still too loud for many tracks. I got kicked off Donnington with it!Today saw a Frustrating session at Santa Pod... it started leaking clutch fluid and coolant. Managed a 13.2 @ 118mph.
Drag racing front wheel drive is like playing football with your shoelaces tied. And in the case of naturally aspirated, with your pants rounds your ankles too.
I'm on a bit of a downer with this car tbh!

Who’s doing the exhaust for you mate?
Maybe it’s time to think FI? My car is a hoot with 350bhp, that in your car would be phenomenal.
Flux Fabrication will be doing it within the next month.Maybe it’s time to think FI? My car is a hoot with 350bhp, that in your car would be phenomenal.
I'm not a fan of FI, it's an added layer of complexity, and space is an issue on the CRX. I'd prefer to tune a bit more in N/A, I reckon 320-330bhp is attainable with a serious head polish, higher compression and some more revs.

Cool build tho. Great shape car and can’t be many left.

At what stage does it become an issue getting power down with the FWD? Surely you must be near that point already?

Thanks mate. 1st gear is un-usable, as it's too short. 2nd gear launches give wheelspin, and a little squeak into 3rd. It's not that bad with the LSD and semi slick / wide front tyresCool build tho. Great shape car and can’t be many left.

Every car at the ring last few weekends has had ar1's on they are the go to tyre now it seems
Scene points yo
What a busy week! The CRX has been in at Flux Fabrications for a few days having the new exhaust made.
Here's it is on the bench. Middle section weighing next to nothing!
All finished, with burnt tips. 10.2kg weight saving over the original 3" system. And down from 116db to 92db static. Happy days!
Massive thanks to Jack @ Flux Fabrications. I can't recommend his skill, hospitality and expertise enough.
Cadwell Park trackday coming soon, after a couple of repairs!
