I just can't wait to tinker with megasquirt. and hey, whats better than having a whole car for mock-up? lol. talk about no down time!

Do it man, do it! Having a mockup car is huge. Make the parts them bolt them on like a kit. The next best thing is another car to drive.

hey, can you show or tell where the maf sensor is?

Maf?

There is no MAF sensor with Megasquirt. Its uses a 250kPa built in MAP sensor. I ran vacuum hose through the fire wall into the glove box.

You can run MS with a MAF sensor (as well as alpha-N), but I can't think of a reason why it would be used with forced induction.

Absolutely correct. There is no MAF. MS is speed density (it can also use alpha-n, or even blended alpha-n, if desired).

Just got back from a trip down south & had a chance to ride in this beast. Very solid build, good tune & FAST as $&$! I fear for anything that pulls up next to this sleeper ie; a thorough thrashing is sure to follow. Props man!

That is cool

By the way have you done a dyno run, or race another car to check out how fast is your ride BBR?

Post by **Brad D.** » Aug 18, 2008 5:04 PM

Well, I haven't run the car at the dragstrip yet. I have a few more things to do to the car before I take it out (mostly suspension related). I haven't "officially" run any cars but I do know that I let my friend with a 92 NSX drive my car and he was thoroughly convinced that my car was considerably faster. Hopefully some dyno numbers will be forthcoming in a few months and some dragstrip times in the fall when the weather cools off.

I wish you the best from my heart!

Well will testing Opel Astra 4door 1,6lt turbo (195 at flywheel on a MAHA dyno and 1290kilograms) when my car boosts it feels more strong than the Opel in not only my opinion but my friend's too, he said "Wow It is considerably stronger than mine" he said, the car was at 0,3 overboost, his was 1,3bar

, so i guess my car has climbed over 220 HP at flywheel, (185 stock)
but that is all just theory, until it is ready and road tested with the Opel

It's always nice to have a "neutral party" drive or ride in your car. It is so easy to become jaded with your power level that the car may not seem as fast to you anymore. A new user typically does not have the same issue and will be a clearer judge of how the car feels. With that being said, it's still not a replacement for dyno numbers or track times.

Indeed those 2 things you mentioned are true!

AHA! no MAF. hmm so a super cheesy BOV with duck call attached is totally possible?

Totally doable.

i think i'm being jacked around with the weld-els. I went to columbia pipe and supply co and they wanted $12.50/ elbow. but I think it was because I asked for 4 and their minimum purchase is $50. assholes...

alijonny · Post by **alijonny** » Sep 06, 2008 1:05 AM

by the way, would there be any benefit to getting 45* els? or just cut down the 90* thanks!

Post by **Brad D.** » Sep 06, 2008 1:25 AM

I didn't bother with 45s, I just cut them down. IIRC the 90s were cheaper than 45s. Are you building a full mani or an adapter?

Mildly amusing but damn that would get annoying.

Start by reading the FAQ. And no, the compression isn't too high. It's actually fairly low, at 8:1. My m30b35 is 9:1 which is still not too high for FI. Turboing your car isn't something you want to jump into without first educating yourself as best you can on the subject.

Just thought I'd throw up a little update on the car. About a month ago I upgraded my brakes to the 540i F/R setup. The stock brakes were in desperate need of replacing and just weren't up to the task of slowing down the car with all the new power. Front calipers were reman TRW units and the rears were used pulled off of a 740il. They were painted with Duplicolor caliper spray paint. I also addes a set of Speedbleeders. These are highly recommended! I upgraded to SS lines all around. Pads are Centric Posi-Quiet semi-mets (for those that don't know, Centric is owned by Stoptech) Rotors are drilled and slotted units from R1 Concepts. Very nice pieces, maybe not quite Brembo quality but nice nonetheless. They have a nice anti rust coating and over a month later not a lick of rust in site on the hat or vanes.
All I can say is that I am amazed by the performance of the brakes. Initial bite is fantastic and the pedal has a nice firm feel. Modulation is now much easier. I feel that the SS lines also contribute and are a great upgrade, even to a stock system. Overall stopping power is excellent, but I have no quantitative testing to report. The Centric pads are very nice and are very low dusting. The dust they do make is more of a silvery grey and is less noticealbe than "black" dust. I will give some more long term feedback on them as time passes.

The next upgrade was to the suspension. Having ridden in LJ's (Nebraska_e28) car with Spax springs and Bilstein sports, I knew that was the setup I wanted to go with. The ride is very firm but composed and easy to live with on a daily basis. I replaced the front swaybar endlinks and reinforced the sway bar mounting tabs on the strut tubes to prevent them from failing when I upgrade bars. I also repalced the rear dogbones. The car now handles the way I feel it should. It's more fitting to the rest of the performance of the car. I only have some pics of the components but will be getting so fresh full body shots of the car, hopefully this weekend.

Here are the plates I made to weld to the strut tube.

And here is current engine bay shot for good measure.

These new candy looks great

i hope you enjoy them a lot m8

Looking good man!!! Keep it up, hopefully you can bring that beast out to 5erFest next year.

well, thanks to big bronze rim, I am doing what I claimed I wouldnt do. I am building my manifold. karma is great, and an employee from columbia pipe stopped by a couple days ago for exhaust and we worked something out for trade for 8 weld els. yeah!
