Rear Mount Radiator - STREET CAR!

[@Itsme-mx5tl]

I am so glad you guys are down to earth and reply to questions/emails. Keep up the great work!!

[@jimmydanc]

Just a tid bit, for a rear mount radiator you need at least a 50 gpm water pump (or stock LS) and roughly 4,000 cfm of fan depending on radiator size

[@demikpre]

Really appreciate the video. I've always been curious about this set up for front mount turbos. I have a question, how about running a smaller radiator along side a front mount. What's the simple way to go about picking a efficient radiator or is rear mount the best way for front mount?

[@darthzman]

+demikpre Your welcome! Hope it helps alot of people that are trying to do something like this. Yes, we have did setups with a smaller radiator beside a front mount, as well as setups with a standard size radiator tilted under the hotside piping up front. We have ran single pass and dual pass radiators as well. The dual pass makes it easier on you with the inlet and outlet both being on the same side for stock water pump stuff in a normal setup. We prefer the rear mount radiator mainly because of all the extra room you get in the engine bay and easier engine swaps when they blow up haha! Some cars I have seen running 2 smaller radiators up front with the turbo in the middle as well.

[@coreyg9]

Bringing it back from the dead one more time, so the only 2 things going to the expansion tank is the steam vent from the heads and the -12 going to the top of the radiator? Or do you have the over flow line from the original waterneck on the radiator going up there as well?

nice set up luv the car man. was wondering how loud is the 55g water pump thanks for your video. building a 1940 chevy coupe front mount ls turbo. trying to figure my room out I don't have much room to work with and rear mount radiator would help out a lot. thanks again. nice

[@darthzman]

Thanks! The water pump is very quiet, it can barely be heard.

[@michaelwhitfield5431]

Which all star radiator is that?

[@g-rodcustoms2448]

thanks for the quick reply. very helpful luv the vids.

[@waybad]

you guys rock!!

[@GrumpysGarage1978]

thks that will make things easy!!!!

[@matsbacklund9034]

Is the radiator a dual pass radiator? Is it working with a meziere wp 319S pump also?

[@blownhatch1]

Nice video, how far do you guys mount the radiator off the trunk floor? or how much clearance does it need?

[@darthzman]

The top of the radiator is close, maybe 1" or so. The bottom just give it as much angle as possible without looking terrible. I'd say that's a good base to go by. There's no certain specific angle or clearance.

[@danielbrealey2924]

How low does it sit when it's mounted??? It certainly frees up some valuable space, doesn't it! Damn, might have to look at doing that when we turbo my V8 VH Commodore shortly

[@darthzman]

Try and tuck it as high as you can while still giving it some angle.

[@danielbluegt]

Do you have a video that shows the radiator mounted? I'm about to do this project on my 89gt. Just wanted to get some ideas on how to mount the radiator. Thanks

[@darthzman]

No i don't, but if I remember ill try and make a quick video on it tomorrow.

[@RecklessRegal]

When the radiator is mounted is it horizontal or does it have some angle in it, if so what's the angle?

[@darthzman]

+RecklessRegal It gets mounted almost exactly how it looks in the video except up high near the trunk floor. No specific angle. Maybe a little less then what's shown here to keep it from hanging down too much.

[@1quikz28]

i get asked constantly about mine

[@joseiturbide4175]

Any year radiator or theres an specific one thanks

[@rdub79lx]

What did you guys do with the steam vent holes from the heads? Are you routing the vent lines back into the coolant system somehow?

[@darthzman]

Yes, on Lil red we run a line from the steam vent back to the expansion tank in the trunk that drains back into the radiator. We have since found an easier way is to buy the Moroso filler neck with 3/8" npt ports already on it ready to go "Moroso 63461" and just go from the steam vent right over to the filler neck and that's it.

[@jg89s10]

Thinking about a similar setup wondering if you ever have any problem wth the tech guys I was told it might be frowned upon at nhra tracks.

[@darthzman]

jg89s10 we run at NHRA tracks all the time. No problems. Main thing is to get a NHRA liscense if your 9.99 or faster.

[@jg89s10]

Thanks for the info. I wanted to make sure I showed up in a legal car for my license passes. I run mostly Indy, Kilkare, and Muncie. Hope to see you there.

[@ky_gearhead]

how do you mount alternator?

[@darthzman]

+Aaron Holt AEI makes a trick setup. www.aeicnc.com/lsx-super-mini-denso-alternator-kit-rh.html

[@BotelloPerformance]

how u mounting it?

[@darthzman]

If the radiator is pretty bare like this one then we just weld some tabs to the sides. Make brackets that attach to the rear floor and bolt it in place.

[@24dll]

How much does your car weigh?

[@darthzman]

+24dll Depending on what we are doing it's usually somewhere between #3150 - #3250

[@24dll]

+darthzman where are you guys located? I saw that you went to a Chicago event and one in Indianapolis.

[@darthzman]

+24dll We're right outside of Evansville, IN. We go to the NMRA vs NMCA Superbowl race in Chicago and we go to Indy a lot.

[@24dll]

+darthzman Sweet. I live 2 hours south of Chicago drag way. Let us know when your coming up here I won't mind coming to see you race. You should race at king of the streets chi town. It's a awsome race to go to. It's at Great Lakes drag way.
