i'm thinking about running methanol w/ my setup this year...is 15:1 compression enough?

thanks

 

We are currently runnnning about 12.5 or 13 to 1 on meth. The next motor I build will have much more. Meth loves compression.

 

i dont think there is a needed compression, but since methanol is less volatile you should be able run up in the teens with proper tuning and not worry about those high heats igniting the air fuel mixture and not your sparkplugs.

isnt bisi running meth, and i think his compression is around 15:1, im not sure on that

 

chad barber told me hez running meth and 15.1

 

I talked to Bisi last year at Rockingham, he said he's runnin 18 to something(forgot what he said) compression. Thats freakin crazy!!!!!!!!!!! But I promise thats what he told me and a friend....

that's what i've heard also...

thanks a lot guys for your help...i'll keep you posted on how it works out...i'm running a 2.4L 15:1 h22...just got the motor in the car last week. we're going to see what it makes on gas first then switch to meth...i want 10's badly.

Adam F...congrats on running 10's last weekend! what kind of whp you making and how much does your car weigh with you?

thanks

 

At fontana they said we weighed 1820, but I dont' think they were correct. We are going to try to weigh it this weekend.

...I run petrol/gasoline still. I ran 18.4:1 compression on my D series engine...not my F.

 

wow, thats crazy, whats the compression on the fseries

 

::devilish grin::

 

were at 16+ to 1 were going to be getting new pistons from rlz should be in 18+ comp. look out bisi. good seeing you this last weekend cloyse jr

 

yeah 18 sounds about right Keep in mind meth is only like 100 something octane.

 

18.4:1 is crazy

 

Dimminishing Returns.

 

What kind of gains are you expecting going from 16:1 to over 18:1? Thats diesel.

Some of the quickest cars in the country are 16:1 and under. Norris are you running that damn high also?

Good thread

 

well I can happily say that we ran 10s @ 12.5:1 cr, just imagine what will happen when we go 15+:1

Its still far from you felix, but theres a weigh station up in denton up by UNT... I wanna get a baseline wieght on my integra so we could make the trip together. If I could keep up you know

 

i've run almost 11:1 on boost with meth

 

i would think you would run into a problem of only being abled to have so high of compression. i was thinkin if the whole motor was zero clearence it would be around 15-16:1. how do u get 18:1 compression? how much displacement is involved?
