Seems like the vent would work best if it was located above the exhaust manifold, that way the heat gets pulled out quickly. Air going through the rad would immediately get sucked out through the vent if it was located forwards more

It's hard to say mainly due to airflow characteristics at varying speeds. As pressure deltas change, so will the effects. But from what I gather, his goal is more for idle than while driving. Like I said before, in that case, hood spacers will work fine, but could cause cruising speed issues. The only real way without calculations AND testing would be to have equipment to be able to just do the testing. Albeit expensive considering you would need a few, but something like it would work:

GCDC B1100-2 Barometric Pressure Data Logger

Most vents or louvers you will find vent towards the back of the car to make use of pressure deltas while hopefully limiting drag. A good example of using the stock hood and cutting it down for evacuation is this car shown below. Making the lip higher on the hood could have negative effects on the car overall. Then again, I am no engineer - just some hillbilly with the Internet.

Yesss

Thats exactly what i was thinking of doing next. Since this hood never been on my car i didnt know how much room i had before i hit the motor or manifold.

I did some cruising last night and got some more numbers.

Going to drive it a bit after work in the sun and record that then swap hoods and see what happens

But you could be JDM as hell like me with simple hood spacers haha jk. The spacers seem to work pretty well for my **** box setup. I'm not really a fan of the tilted hood look, but it does make a positive difference with heat soak.

ok did another log. This was after messing with my accel fuel. lots of stop and go and idle time.


under hood temps peaked 146 while cruising

Tomorrow well see if the little hood scoop makes any changes

I put the hood on so I can log temps on the way home from work and decided to do a quick drive


So far the temps drop a hell of a lot faster when the rad fan kicks
on and off. Temps are 20-30 degrees cooler too. I can feel a lot of heat rising from the scoop when the fan turns on also.

I should put my junk hood back on my car and do some testing too like you are.

Yeah man. This heat soak is no joke lol


Ok so today on the way home from work in traffic my iat temps stayed pretty stable. Barely dipped above 100 degrees but I think that's when I pulled up to my house

Sup guys in looking at some new tires I'm making 286 hp on a dyno jet. Stock ls turbo with a gsr trans . I'm looking for something to hook up on the street. So Im looking at some Dunlop direzza dz101 205/50r15 can I get some opinions ? Maybe point me at some other tires that are not to costly

boosted94gsr

Nitto neo gens! That's what I run and they hook really good. I cut 2.0 60ft times and ran mid 12s all day long with them. I got a set of 4 off eBay for under $300 shipped. I have 205/50-15 btw

phaphon

The dunlops Are the same price and are ultra profoance tire wouldn't that be better? I was also thinking of bridge stones re11 but it's about double the price

boosted94gsr

I just looked I paid $282 shipped for all 4. I don't have experience with the others you listed, but I know a lot of people have really good luck with the neo gens.

phaphon

Yeah it's just I searched and on Google a old thread came up and a member brought up to my attention that nitto are all season tires not racing tires . So yeah ? I hear a lot of good things about nittos it's just if I can get some ultra high performance tires I think I want to try those

boosted94gsr

If I ever upgrade from the neo gens I'm going with the r888 in 225/50-15.

m4xwellmurd3r

I have dz102s (update from the 101s) 20psi tire pressure in my car cut like, a 2.40 or 2.50 60ft? Cant remember. Car wanted more revs cause it was bogging slightly launching at 3800rpm. I'm not boosted though

phaphon

Oh okay would you say they grab good m4xwellmurd3r? And boosted gsr i would let to get them too but the Dunlop are way cheaper

m4xwellmurd3r

They grab good for my car, but I'm only putting down around 145whp on a stock head ls. I think 200+ need at least R compound tires to hook up good. Once I get my fun head rebuilt I'll probably have to look into getting some r compounds or slicks for the track

phaphon

Oh okay well I'm on boost by gear 5 psi first 7 in second 14 3rd , I'm sure it would be hard to hook in first. I'm just looking for something to possibly hook in second, I already have a lenso set up for the track

Love my neo gens, best tire for the money

Had to fill up some more e85 last night.

I tried to drive as low on 91 as i could the first time i filled up but only got e60.

This time it went up to e80.

I raised the boost up to 16 pounds and damn does this turbo spool up fast when youre asking for more pressure. Butt dyno thinks it was almost at 280-300

Got a cool sticker too

I was thinking about going the E85 route but what scares me is the fluctuation in octane I hear about E85. Sometimes you will get E85 and sometimes you will get E70 or below. What happens if you tune on E80 and then get a batch of E60?

LightningTeg

Then the car runs rich. Not really an issue unless your making alot of power. I've never had any issues with inconsistency even driving 800 miles across the midwest and filling up in 4 different states.

Real ems with gm flex fuel sensor bro

When this tank runs out i can fill up on 91 without touching a single setting or flipping a switch.

It also tells you the temp of your fuel which is cool too.
