Registered Nutter Posted January 17, 2002 Share Posted January 17, 2002 My Sup is going to go away for some more work to be done on it and was wondering what intercooler i should go for bearing in mind that i will probably not ever be going for big twins (or at least i keep telling myself that). But i do want to push the hybrids as far as they can take me. This is my current spec: Hybrid Turbos HKS Super Dragger Exhaust Intercooler Hard Pipes High flow front pipe Blitz SUS Power Induction Blitz BOV Racelogic adjustable traction control and launch control 18" Blitz Z2 wheels Eibach Springs Bomex Sideskirts and Front Lip Big Brembo cross-drilled 356mm brakes Top Speed Delimiter Upper Glovebox/airbag Pannel Housing EVC-4 Electronic boost controller with Scramble Boost Button Oil Pressure Guage Boost Guage Exhaust Gas Temperature Guage Quote Link to comment Share on other sites More sharing options...
GavinL Posted January 17, 2002 Share Posted January 17, 2002 Hi... I reckon the "S" type would be fine. I know that I am not going big twins or single because of lag so an easy decision for me However if you are in any doubt go for the "R" type. I'm sure that if you should make the wrong decision their would be plenty of people on this BBS who would be interested in it secondhand.

Lee Burley Posted January 17, 2002 Share Posted January 17, 2002 Or have a look at the "Intercooler Throughput" thread started by Chris Wilson... looks very promising. You could have an intercooler and rad stacked on top of one another.... very sexy! I went for an S-Type from Justin, and fitted it myself. I am very happy with the lower EGTs and looks. If I ever went for anything bigger than hybrids the cost of the resulting work would probably be so much that swapping the intercooler for an R-type or bigger would be a drop in the ocean!

Alex Posted January 17, 2002 Share Posted January 17, 2002 R is the top spec rated at upto 800hp I believe. S upto about 5-600hp. The S is thinner (by at least 30mm) and so easier to fit in the space. But also consider the GReddy, Blitz and Apex'i units. Worth doing some checking on the web.

Registered Nutter Posted January 17, 2002 Author Share Posted January 17, 2002 while the car is away she will be having a new fuel pump and oil & water temp guages fitted and should i see any temperatures getting to high she will go back for oil cooler & water injection etc so ill probably go for the s-type. what sort of boost levels do you think ill be able to run?

I would suggest you are at the point already that an oil cooler would be very desirable. I personally would rather have cooled oil than an oil temp gauge anyday. As for boost levels, all depends on the Hybrids. They come in different specs from different suppliers you might need to refer to your tuner for that answer.

I guess around 50-100 degrees, although that is not from any scientific measurements, and there are so many other variables such as air temperature, humidity etc so it is difficult to compare like for like. All I know is my EGT warning used to come on at full throttle in third/top gear before the FMIC, and doing a similar thing with the FMIC fitted I am running 50 degrees or so below the threshold.

Alex Posted January 18, 2002 Share Posted January 18, 2002 Martin, and all, The GT spec isn't an option as the question was about a car on Hybrids....so I would go for the R spec but I know Apex'i make intercoolers which are also of an appropriate size.

Adam W Posted January 18, 2002 Share Posted January 18, 2002 So is the GT-Spec better than the other two IC's, or worse? If better, is it bigger, or just more efficient? I'm not sure I've ever heard of one before. Quote Link to comment Share on other sites More sharing options...
Guest Martin F Posted January 19, 2002 Share Posted January 19, 2002 It is bigger, and i have a feeling it is more efficient through a different fin design but would need to confirm. Quote Link to comment Share on other sites More sharing options...
Ring Master Posted January 19, 2002 Share Posted January 19, 2002 GT type does use a more efficient core; unfortunately HKS dont do one for the JZA80. S Type is £750+v core size 600x301x65 r type is £1385+v core size 600x302x97 Oh, pipe work on the R type is the lovely mirror polished stuff that makes my knees go wobbly.... Forget about power ratings, just buy the most expensive FMIC you can afford (an R type would be a worthwhile mod on a stock supra). Quote Link to comment Share on other sites More sharing options...
Alex Posted January 19, 2002 Share Posted January 19, 2002 The bigger the intercooler the more lag you will suffer unless you do other mods at the same time. Why induce more lag than strictly necessary if your only going to need the efficiency of a R type. Quote Link to comment Share on other sites More sharing options...
Adam W Posted January 19, 2002 Share Posted January 19, 2002 Not saying you're wrong Alex, but I thought that big intercooler=big lag was one of those tuning myths? I'm sure I remember hearing that from someone . . . Quote Link to comment Share on other sites More sharing options...
Guest Martin F Posted January 19, 2002 Share Posted January 19, 2002 I think what your saying is correct Adam, that additional lag due to a larger intercooler is a bit of a myth. Yes it's proven that a larger intercooler will add to lag, but the amount is so minimal that you are unlikely to notice anything. Now if only i can remember where i saw those tests.

Steve Cargill Posted January 19, 2002 Share Posted January 19, 2002 It will a little beacuse there is more space in between the compressor and the cylinder to bring up to pressure. Here's a bit of maths, as I understand it.... 3 Litre car - 1.5L air per rev at 1ATM. At 3000RPM that is 75 litres of air per second 'consumed'. Adding a few litres of extra space is only going to make a fraction of a second difference to pressurise. Quote Link to comment Share on other sites More sharing options...
Paul Whiffin Posted January 19, 2002 Share Posted January 19, 2002 Greddy 3 row I/C is regarded as one of the best in the US, most of the big power Supra's seem to use this. I think thats what Leon has got in his beast. With regards to going Single or Twins, in my view going the twin HKS route to me seems a bit of a waste of time unless you are drag racing your car, from what I've been told lag is a major problem. Single seems to be better, apparently an Sound Performance SP57 kit will spool quicker than the stock twins in sequential mode and still able to produce huge amounts of power.

Syed Shah Posted January 19, 2002 Share Posted January 19, 2002 Er..but thats American. Look on their Supraforums ard you'll see a SP-74 will a 85mm compressor wheel that they claim to be able to gain full boost by 4000rpm. Most of their stuff is a load of bs, like 550rwhp on stock twins etc Quote Link to comment Share on other sites More sharing options...
Paul Whiffin Posted January 19, 2002 Share Posted January 19, 2002 I don't think it is, I have spoken and personally met a few owners of single turbo'd cars and they seem to know what they are talking about to me. May be the HP figures seem a bit unrealistic but qtr mile times don't lie. Anyway I'll be able to tell you all soon..... Quote Link to comment Share on other sites More sharing options...
Alex Posted January 20, 2002 Share Posted January 20, 2002 Quote: from Syed Shah on 10:59 pm on Jan. 19, 2002[br]Er..but thats American. So? They have much hotter weather to deal with, so they probably are pretty good at cooling the car. Also an American car holds the 1/4mile record for a Supra.... They do have a different rating for HP but who cares! Big single is the route I'd rather take.....but possibly mid-twins...and a GReddy, Blitz or HKS intercooler will be supplying the cooling. Buy the one that you like and can afford. They all work, "pays your money takes your choice" Quote Link to comment Share on other sites More sharing options...
