"Reliable" 300hp Type 1, possible?

[villemil]

So the question is. What would around 300hp Type 1 streetable engine need? Is that even possible?

[Schweg]

What’s your definition or reliable?

I would say yes Clone just put down 221 hp on pump gas and drives his all summer. With more displacement or RPM I would say 300hp is achievable.

[buguy]

Of course it is. It's almost easy with a turbo.
A stroker, turbo, intercooler, and 15 psi or so and your there.

[villemil]

On my "to-do" list before the engine is to do full painjob, full rebuild for the chassis, roll cage, good suspension and brake setup to support that power mainly for drag racing and for street use too. After that I was planning on doing EFI with intercooler. No other plans for the engine.
I had a 1641cc turbo engine before running around 21psi of boost. On butt dyno it was somewhere around 150 horses I believe
Could 2110cc with good designing do the job for me? I mean reliable by 1-2 years of use with decent abuse on the streets since I mostly leave the traffic lights on full throttle lol. And I sometimes will be going for drag events too.
Any suggestions what could be the best route to take with best bang for buck. Going to run E85 fuel since that will maybe be the best option for me. Really well available in Finland.

[Schweg]

78x92 thick wall with full flow add EFI and boost run e85. Get a 1.4 ratio cam and rockers aim to make power around 6500-7000 build up all the parts you mentioned transmission, and chassis to handle the power and not shake apart and it will be just fine.


Are you looking to change your cam from the TSC-20? Also how did you like it in your 1641?

[villemil]

It did quite well. Honestly I was suprised how my little 1641 liked that cam everyone told is way too big for such a little engine.
It was ripping really hard on top rpm's. Redline was around 6000 and it was doing really good from around 3500 to that redline point.
I really don't know about any engine specs yet for the new engine. I will propably be building the chassis and transmission etc for the next year or so to get it as good as I can possibly get.

I decided to make it a bit longer project now to be able to put more money to it and create something I was always dreamed of

[buguy]

A 1641 at 21 psi was probably closer to 200 hp.
A 2110 would certainly do the job. That size engine at 6500 rpm and 18 psi would give you 300 hp. Want more power? Just increase the boost or the rpm. Or both! With E85 you can do so much. I ran 25-30 psi on a basically stock engine for a year with no troubles.
Bang for the buck is the tough question. I spent the most money on the ecu. Bang for the buck would probably be microsquirt. That would give you the basics you need. For me, I'd do 82x94 and lower rpms for longevity. Make your own exhaust and intake. Cam in the FK10 area with 1.4 rockers. 9:1 compression with E85. Heads i would get the best you can afford.
Also with that kind of power you probably won't be leaving the lights at full power. You will just smoke the tires every time. Don't forget to save for a trans and axles. My axle broke in the first 15 miles on my stroker and i wasn't even abusing it.

[woodsbuggy1]

Definately EFI, Very good brakes and expensive transaxle along with suspension upgrades, just keep in mind that 50% more power will probably cost at least 4 times as much as what you have now.
Good Luck

Bang for buck ECU will be Speeduino, definetly suggest you checking into that if you don't know what that is
I'm capable of making my own exhaust and intake and most of the required machining for the engine since I'm a machinist.
For transmission and axles I will get something from "Kuplapaja" from Finland if you know what that is, they have made one of the best ones for past 20-30 years or so I believe.
Do you have any knowledge of Mofoco heads? Maybe Mofoco 050? Are they good for the price because those seem pretty "cheap" for what they call they are?

[buguy]

I've never used Mofoco myself.

[villemil]

Yeah basically the thing is that I have always dreamed of drag racing real fast and I want to make that big leap towards that dream now.
Really need some push towards the right direction tho.

[buguy]

Well you are in the right part of the world. There are some fast guys in your region.

[woodsbuggy1]

You might want to seriousy consider building a 2nd car for race, it is very difficult to serve 2 masters. Spend some time finding some race cars that do what you want then copy what they have done, not sure it is possible to build a race car that has good street manners especially when using 50 year old platform. Not trying to discourage you but don't want you to be disappointed either.

Well making this "race car only" is always an option, not really sure tho what I want to do yet. Not even sure if I'm ready to race a 300hp bug yet. All this is only in my dreams but everything is possible since the car is fully disassembled already.

[Clonebug]

Well.... not trying to burst your bubble but seeing how your first engine only lasted 1000 km....which in amerispeak is 620 miles.......you got a lot of learning to do and building something with 300 hp is going to cost you a lot of dough in a short time if you treat it the same.
A 300 hp vw engine is not easy to get and if it is N/A it is near impossible without a very extensive budget.
Even 300 hp from a turboed engine is not going to be cheap. Tune it wrong like your first one and it's going to hurt.
But go ahead and dream.......

My opinion for a build...

78.4 X 92 TW
Good rods.
300 duration cam with .530" lift using 1.4 rockers
6500 rpm
17-20 lbs. boost
Intercooler and/or WI to keep IAT's to 95*F max.
Stage II clutch but will need a darn good disc setup.
Transmission with a lot of goodies in it.
