Caltex E70 And No Intercooler?

[Super Drager]

Hey guys, just a thought but how would an ethanol powered car go with no intercooler and mild boost say around 14psi?. Just something that i'd be interested in knowing.

Drag car?

From what I gather ethanol cools nowhere near as much as methanol

[Super Drager]

Nope weekend cruiser, i'm going to fit intercoolers to mine but just wanted to know about the above.

[zebra]

Fair enough

But given you can pick up new inter coolers for 100 bucks you would be silly not too IMO

If space is an issue than WMI is an option

[AngryRB]

i would be suprised if it didnt cope, me and my tuner are amazed how good this stuff is, im running no more than 20knock on the power fc... its sweet as

but you'd be silly not to do a GTR intercooler atleast... my intercooler was only $400 and $300 to fit up so dont try and be cheap with it or you'll end up getting a crap result..

wow.. just saw you got 3L twin... man that has massive potential with some decent turbo's and E85... happy times ahead if that is done right.. a 300zx was my second choice of car if i didnt get the r33...

lol... interesting way to gauge the effectiveness of a fuel???

Lol

Well my less than 5 knock on my old pfc makes 98ron look even better

[AngryRB]

well, judge me all you like, im just saying 20psi 320kw and very very little knock with 6degrees of extra timing ...

im confident that this fuel would do ok with only 14psi and conservative timing and still make some decent numbers, but i did say put an intercooler on it didnt i??

ill say again.. its very good fuel and you can achieve above and beyond 98 ,, my tuner will vouch for that too

[AngryRB]

less than 5knock just means your soft cock lol

[zebra]

Any knock means youre eating away at pistons and bearings

Besides you could be seeing readings of 200 on the pfc but the engine isn't pinking

They just read noise

I'm still pondering whether i should go the WMI route or the E70 route. A water/meth kit is cheaper than new injectors and a pump. Not 100% sold either way due to my setup not being that "hard core" but needing one or the other to put any useable boost in. The Base Map i'm using for it has 15 degree's removed from peak torque and 5 degrees removed up top and was used in a similar setup on only 7psi.

[zebra]

I'm in the same boat, I won't be knock limited on 98 so I have nothing to gain either way

But I like the WMI to keep iat's down as I suffer from heats oak bad, as would a 300 I guess

[AngryRB]

dunno what you guys are on about really.. do you actually run flex fuel or are you guessing about it, cause i watched my car on the dyno and being tuned by Gavin Woods whom i fully have confidence and respect for... does an awesome job and absolutely safe tunes... when you go get a job as a tuner and succeed like he has then come back and preach your knowledge with results like he has and then ill agree with you..MAYBE

just trying to help with some constructive comments.. GL with it the 300ZX should love it.. ive drove a 300ZX non turbo and turbo and even the non turbo had balls so will be interesting whatever you do

Ethanol is just like methanol. It would work well without an intercooler. Obviously E70 isn't as good as methanol so the cooling effect isn't going to be as good.

I'd still run one, not worth the disadvantage

Well considering the RON (research octane number) value is measured via knock feedback on a variable compression engine I would suggest that you would be able to make some fairly valuable results from monitoring knock levels with 98 vs e85.

To the original poster if you are knock limited than you obviously need higher octane fuel to achieve a better result/higher knock resistance. An intercooled will help cool the charge making it less prone to det but will not aid in octane. Wmi will do both these things. If it were my car I would make the intercooled fit and run e70 - this is obviously the best solution..

From what I've seen e85 vs methanol - it is nowhere as good at keeping temps down. We had no cooling issues with a methanol injected 350chev - swap to e85 bam, not enough coolant capacity/radiator and we had heating issues. This was a drag car with small radiator.

You only need to look at the extra volume of fuel required compared to e85 to see where the cooling comes from.

[The Dan]

Yes but comparatively run M85 and see if it's the same

Thier point was the fact your tune does not knock has little to do with the fuel and more about the state of the tune. And basically overall your intercooled results are irrelevant for this thread. So more-to the point, no-one is sure what you are on about!

To the OP - VL's were running what, 5psi through a small T3 and were ok and you could get upto around 8-10psi IIRC. This is back in the 80s

That said - it's not just about the amount of boost.

14psi through a t04Z or 14psi through a stock GTS-t turbo? Two very different ends of the field and resulting heat. saying "14psi" isn't relevant in it's current context really without knowing the entire setup. Your setup will also be quite sensitive for sustained use as well as heat increases.

You'd need to get a few sensors going IMO and monitor it carefully and work your way up. It might be fine now in cooler months, and all of a sudden one warm day, 1hr drive and all of a sudden you've got stones under the bonnet

[Dan_J]

now ethanol has a higher octane level then ULP although i thought its cooling of intake temps is worse then ULP, correct me if i'm wrong?

so ethanol does lower intake temps more then ULP ?
