Uh oh

I must owe Todd a shitload by now

In that case I'm sure a lot of people owe him money. Pay you for emailing questions, I've heard it all.

I kinda think Todd was kidding %)

[QUOTE="Vento9"]In that case I'm sure a lot of people owe him money. Pay you for emailing questions, I've heard it all.[/QUOTE]

I think you have missed the point. You seem to think that everyone here owes you answers. We don't owe you anything. If you demand to know than you should be willing to pay. Otherwise, read every post in this category and you'll find the answers. I have already typed a book about your questions in response to another post.

In the meantime try having a little respect for those of us who can help you. Show your ass more than once and nobody will help you.

When did I say anyone owes me anything? What is the primary purpose of this forum, or hell any forum at that? A place to ask questions and reply to questions posted, right? Obviously I'm having trouble finding the exact answers I'm looking for. So maybe you could have a little respect for someone not as knowlogable on the subject as yourself and help out instead of pushing someone aside.

Everyones gotta have a chip on there shoulder as it's crazy to ask such questions. My questions were legit so if you don't feel like answering them then thanks Anyway.

Something that no one said is,

Not only is TCD a company but a homegrown company from here that came with 2 great guys,Todd and John,
well John anyway.......atleast he would stop when he was in town.....

But You get what you pay for and from what I have seen....if you piece it together you end up with pieces ......besides lost $$$.....

Do it once and do it right....

plus TCD kits crank out a shitload of power compared to stock E23 stuff, updated and pretty sweetttt.....

All this is coming from a stubborn NA guy too.....

Hey I thought about coming by but I actually wanted to see my family more. I'll be down in July too.

This has nothing to do with TCD vs 745i stuff. There is no doubt that the 745i stuff will work adequately and for a reasonable amount of money if you get lucky.

I'm sure they're a great company, but the simple fact is I'm not looking to drop $4200 on an 19 yr old car. Bottom line, just not worth it in my opinion. From other forums I've seen there are people out there that have gone the 745i route using a variety of factory and some aftermarket parts. I know I'm going to have to go through TCD for the RRFPR, injectors and who knows what else.

I really do wish I had the money to drop on a new kit to make my life so much easier but this is my beater. I have enough money tied up in my vw, as it is. I really don't mean to come off like a prick to anyone, and I've seriously been searching through a ton of bimmer forums for more answers on this subject.

So thanks for all that have contributed, I don't want to get this locked. Just want help

John,

It's all here already. I have written the book once already. You just need to find it.

For enough, Thanks Todd

hello! a lot of you have turbo kits on your 535 and many of you have it with stock internals and everything.but i was thinking that most of you have the 136kw (8.0 compression ratio),but i have a 160kw (10.0 compression ratio) engine and the pistons on this engine are with high dome and i think not very suitable for turbo.so i would like to know if anybody has the 160kw engine with turbo and how much power can you get from this engine with stock internals,and on what psi you can drive daily so that it wouldnt do any harm to the engine.i dynod my car today and the engine had 200 hp and 150 from the rear wheels and 290 nm of torque and its just not enough .

well i have the 9.0:1 compression motor. right now i have 5 psi, but will be boosting it to 15 psi intercooled and with standalone management.

it would be interestig to know what TCD thinks about it. is it very neccesery to change the pistons?and how much psi you can run

With 10:1 static compression you could run upwards of 12 psi boost. This would be pushing the limits on pump gas and running on the edge of detonation. This is a rough estimate.
Running at 0.5 bar (7.5psi) you would realize roughly a 50% increase in power... again this is a rough estimate... lots of variables.
We have run all of our cars on stock internal components. Of course, the more power you make, the higher the stress on everything.

so if i run 6 or 7 psi with the high dome pistons and 10.0 compression ratio it wouldnt be much of a problem? %) have you turbod an euro 535 (218hp) and what dyno results can you get.and as i understand intercooling will be a problem

Wasn't there JUST a thread on compression vs. boost? Maybe I'm hallucinating. At least I hope so...

We have not turboed a euro yet, but, as I stated, a rough estimate for power would be a 50% increase if you ran 0.5 bar boost. There are, of course, variables like the cam shaft, actual health (compression) of the engine, etc. There are turbo calculators on the net that allow you to plug in the specs of your engine and get, again, a rough estimate of power output.


[Edit by Sweeney on [TIME]1119805566[/TIME]]

comression is 12 in all6 cylinders.i have a schrick 284 degree cam.

[QUOTE="E28"]it would be interestig to know what TCD thinks about it. is it very neccesery to change the pistons?and how much psi you can run[/QUOTE]

i have not read any articles specific to our cars but i have heard (from word of mouth) that the rods are strong as hell and can take almost anything you can throw at them. i have also heard that the pistons are the actual weak link. i have also heard this about other bmw motors such as the m50 motors, the rods are strong as hell but i can't speak about their pistons. i have also heard that bmw's in general have weaker fasteners on the hg. can anyone speak to the validity of this. maybe sweeney since you do seem to posses the greatest knowledge here about our motors.

As I see it, the M30 engines are really good to ~375 crank hp. If your going to use power above that level on a consistant basis, your engine longevity will be suspect. It may have some type of failure in 5k miles or 50k miles, but somthing will fail, a head gasket, crank beraing, somthing. Unless you build a special engine, I'd stay ~350hp, and save the big power runs for dyno runs and special fun runs

russ, is what i have said true for the most part? also, my car is going to be boosted to 15 psi, intercooled and tec3 tuned for everyday driving. of course, come winter time, i will probably drive this thing twice a month and not boosting real hard. shouldnt put more than 5-7k miles on it this coming year. and i plan on saving now incase i plan on a rebuild or other upgrades next summer.

My experience on boosted M30s is head gasket first, crank bearings, then pistons. Your probably right on the rods, good and strong. I've not heard about pistons being the weakest link. The only time I've heard of them failing in boosted engines when they completely melt down from catastrophic failure.

RussC

I know of a couple that broke pistons.

ok, now that i think about it i hear a lot of failed head gaskets as well.......TODD and DUKE!


[Edit by gol10dr1 on [TIME]1119895300[/TIME]]

Yellow 1x, Tjn 1x, Head gaskets are usually the first to go. Then the bearings when they turn themselves inside out and send a rod through the b lock, then a piston meltdown. Its gotta be pretty hot in there.

Running ARP studs, pistons failed (collapsed ring lands on #2 and #5) with a sealed head gasket. Happened somewhere north of 20 psi though, using pump gas (wastegate had more spring in it than thought...ouch!)
